Here is detailed information about flange bearings.
What Is a Flange Bearing?
Flange bearings are the bearings which have a cylindrical shape body at its’ one end attached with a flange.
Flange bearings have the capability to bear both radial and lighter thrust (axial) load. Flange bearings consist of a single flange at one side.
If the axial pressure is given, then the flange of the bearing will try to stop the flange bearing to move in axial direction.
Flange bearing primarily consist of an insert and housing of a ball bearing which is flat in nature.
Flange bearings are designed with two, three and four bores for linkage. Such kinds of bearings are referred as two-hole and three-hole flange bearings as well as four-hole flange bearings.
Central axis of the rotating shaft is perpendicular to the contact surface and it consists of an internal flange ball bearing hoop. In this way, the shaft can support heavy load.
A flange bearing consist of a lip cover on the external hoop that aids in mounting and locating bearing in applications.
Flange bearings have the ability to bear higher pitches, vibrations as well as excessive heat and are more applicable in automotive industries.
How Are Flange Bearings Used?
Flange in these kinds of bearings is used to locate four-bolt bearings. Flange bearings permit the rotating shaft to slide pass perpendicular to the sliding surface. Flange bearings also offer double flanges when required.
These bearings are applied in a locking mechanism of two or four-bolt on the inner side of flange.
Flange bearings are also supplied in a sealed as well as open form and consist of a wide bore. Some flange bearings are used to align the tilted long shaft. Flange bearings and ball bearings are very small in size.
Flange bearings can be applied in applications which have speed up to 1200 revolution per minute (RPMS). Flange bearings are easily fitted in the pulleys as well as in hubs of the wheels and rollers.
Flange bearings with sealing on the inner side of the housing consist of a hoop that can rotate easily in any direction even in the harsh and steady environment.
Flange bearings can reduce vibration issues, bending of the shaft and reduces higher load.
How do you Measure Flange Bearing?
It is vital to measure the bearing to determine which type is the best for use. The dimension of a flange bearing is measured with the help of a caliper. Points to note when measuring the flange bearing are:
- Measure the internal diameter (ID) of the flange bearing
- Determine the outside diameter (OD) of the flange bearing
- Now, determine the total lengthy of the bearing along with the flange
- Determine the width and thickness of the flange.
The size of the flange bearing is determined in such a way:
- Shaft size determines the possible diameter as well as the bore diameter of such bearings.
- Height of the mounting surface is another reason in determining the size of a flange bearing.
What Is the Purpose of Flange Bearing?
Flange in the flange bearings helps to mount and align the bearing during their installation. Flange bearing is designed in such a way to give support and strength to the shaft which is placed vertical to the area of the mounted bearing.
Flange bearing removes the flex of the shaft which is caused by over-speed and overload. Flange bearings are best for all industrial tools and equipment and various fields.
Flange bearings are used to mount ball bearings as they are water-proof and dirt resistant.
What Are the Applications of Flange Bearing?
Flange bearings are widely used in many applications such as:
- Machines of food processing
- Conveyors rollers
- Handling of material
- Medical equipments
- Agricultural machinery
- Power transmission
- Small rotary motors
- Office equipments
- Precision machinery
- Pressure rotors
Which Material Is Used to Prepare Flange Bearing?
Flange bearing consist of an insert and housing. Flange bearing can be manufactured from metal, thermo-plastic material as well as fiber reinforced composite.
Housing of a flange bearing is made of various materials such as:
- Cast iron
- Pressed Steel
Flange bearing housing is made of cast iron with a minute addition of carbon and silicon. Cast iron is a composite substance. Cast iron faces stable and meta-stable period of solidification when exposed to heat.
Plastic material of flange bearing housing is a family of synthetic and organic material which is thermoplastic and setting polymer. While the common forms of plastic are
- Nylon ( it is tough and possess good pressure rating)
- Acetyl ( produces less friction and is chemical resistant)
- PTFE ( it offers zero fatigue and resistant to corrosion)
Plastic Flange Bearing
It is referred as carbon steel with low amount of carbon.
What do you know about Flange Mount Bearing?
Flange mounted bearings are called the unit bearings which is present in the inner part of the housing. The bearing units are given a rigid place by the housing to rotate in the clean environment.
The external ring of the flange mount bearing is fixed in the housing while the internal ring has the capability to rotate. Such bearings are mostly used in the applications which have light duty.
The housing of the flange mount bearing consist of high-precision base surface which lies vertical to the flange bearing central axis and also possess holes for mounting which are marked as two-bolt holes, three-bolt hole and four-bolt hole.
Flange mount bearing can be replaced easily than rotary bearings which are press-fitted. It can withstand heavy load and prevent the deflection of shaft that surely result in damage.
Flange Mount Bearings
What Specifications Are Required for the Performance of Flange Mount Bearings?
Specifications of the bearings are vital in selecting the bearings. Here is a detail about the specifications of flange mount bearings.
- Maximum speed
It is the optimum speed at which the flange bearing can easily operate. Lubrication, temperature and pressure have a great effect on the speed of the flange bearing.
- Service life
It is also marked as a bearing life of a flange mount bearing or a rating life (L₁ₒ). It is a life which the similar flange ball bearings will survive before facing fatigue. It is also about 90% durability of such bearings.
- Load capacity of bearing
Loads applied on the flange mount bearing are of two types such as axial load and thrust load. Axial load is 50% of the radial load. In this case, select the flange mount bearing on the basis of radial force.
When the axial (thrust) load becomes equal to the radial load then select the flange mount bearing on the basis of combination of both the loads. Loads are of:
- Basic dynamic load rating (C)
- Static load rating (Co)
L₁ₒ = (C ⁄ P)*3
- Operating temperature
Flange mount bearing operating temperature rely on the retainers, lids as well as lubricant. When the operating temperature of the flange mount bearing is elevated beyond the required limit, grease deterioration occurs.
Grease stick with the lip cover and the internal ring of such bearings resulting in damage and friction.
What Are the Advantages of Flange Mount Bearings?
The advantage of flange mount bearing is such that it plays a vital role in various electric devices and toys.
Flange mount bearing is the convenient bearing in a way that it can withstand load and makes axial displacement easy. It combines the flange with the bearings.
Flange mount bearing is very economical as it does not need any bearing seat due to combination of flange and bearing.
Hollow shaft of the flange mount bearing make it lighter in weight and provides with low torque and strong rigidity.
Describe the Types of Flange Bearing?
Here are different kinds of flange bearings which totally rely on the housing style and the type of bearing. Here you will encounter various types of flange bearings.
Flange Roller Bearings
Flange roller bearings consist of rollers as a main feature. They have the ability to bear static load in motors and produces less friction.
Flange roller bearings can withstand greater radial forces. Such bearings are available with a cage, internal and external ring in addition with a separator of rollers. The subtypes of flange roller bearings are:
- Flange Cylindrical Roller Bearings
Such types of flange bearings can withstand maximum radial and minimum axial load.
- Flange Spherical Roller Bearings
Such bearings consist of rollers in the external and internal ring raceways which helps to minimize the friction produced.
- Flange Tapered Roller Bearings
Such kind of flange bearing has an inside ring and an outside ring. These bearings have a wider contact surface and capability to carry both thrust and radial loads.
Flange Tapered Roller Bearing
Flange Ball Bearings
Flange ball bearings consist of balls instead of rollers. Such bearings have inside as well as outside rings including cages and separators for balls. Such bearings have the ability to produce low friction coefficient.
Flange Ball Bearings
What Is Four-Bolt Flange Bearing?
Four-bolt flange bearing is the bearing which consists of four holes. This bearing is placed in a radial direction across the axis. This flange bearing has circular or square housings.
Four-bolt flange bearing is a ready to install bearing which has a shaft vertical to the contact surface.
Four-bolt flange bearing has a housing made of cast iron as well as steel bearing unit along with a shaft to carry radial as well as axial load.
Four-bolt flange bearing contain a set screw collar for locking which serves as a safe attachment with the shaft.
Four-bolt flange bearing has a rubber seal to avoid leakage of the lubricant and stop entry of foreign agents.
Four-bolt Flange Bearing
What Are the Ways to Extend the Bearing Life of Flange Bearings?
Bearing life is the 90% reliability of the bearings before any failure of fatigue. Flange bearings can carry radial load but can also withstand combination of both loads.
The measures which are used to extend the bearing life of flange bearings are:
- Make a circular spacing in the bearing lifter and the ring. This will help improve the inner structure of the flange bearings and increases the life.
- There must be use of FEM analysis tool which improves the strength of the cage by modifying the structure and density of the flange bearing. In this way, bearings do not worn out easily or face any damage.
- Use a guided groove in the ring to prevent any damage of the surface which is caused by oil lubrication. This will help increase the bearing life of flange bearings.
Explain the Methods to Installation Flange Bearings?
Flange bearings are the bearings which support the shaft that is placed vertical to the placing area.
Installing of flange bearings is a great challenge because the outer shell is made of thin aluminum.
The methods used to install flange bearings are as follows:
- Machine the housing according to the given inside diameter instead of a press-fit. Add adhesive to the external diameter and let the bearing slide into the housing.
- Adhesive of the bearing must not collide with the liner of the flange bearing and affect the clearance of the flange bearing.
- Freeze the flange bearing for few minutes and after removing bearings place them inside the housing. Temperature increase result in fitting of housing and the flange bearing
- Always use a mallet to install flange bearings because installing a new flange bearing may encounter damage due to hammer force.
What Is the Design of Flange Bearing?
Flange bearing is designed in two ways depending on the load capacity and performance. The design is vertical mounting or horizontal mounting. Former design is called as insert bearing and the later is called as flange mounted bearing.
Insert bearings are mounted on a shaft. Such bearings have a slip-fit feature to mount on the shaft. Internal ring of the insert bearing is extended to give a support to the shaft.
These wide inside ring bearings are used in heavy duty machines.
Insert bearing structure has an advantage that it is designed with a seal or provided open form.
Housing structure is made of famous stainless steel material, zinc plating, nickel plating as well as of chrome steel and pressed steel.
These bearings are designed in a way to can carry heavier loads.
This design of flange bearing consists of locking mechanism in the form of set screw and a squeeze collar.
What Are the Characteristics of Flange Bearings?
The major characteristic of flange bearings is the setting of the flange with the bearing. When no connecting part is available at one side of the shaft then the shaft is placed in a flat surface.
Flange bearings offer easy replacement due to unbolted and bolted housing.
Flange bearings consist of more durable and versatile units. Flange bearings are maintenance-free.
Flange bearings can compensate misalignment. Flange bearings are corrosion resistant
Flange bearings provide greater resistance to wear. Flange bearings are measured in millimeter.
Explain the Housing of Flange Bearing?
The housing of a flange bearing is designed in three forms such two-bolt housing, three-bolt housing and four-bolt housing.
Such type o flange bearings are like a diamond shaped bearings. It consists of two-bolt holes for mounting fixed at both sides of the flange bearing.
A straight line is drawn perpendicular to the central axis of the mounting hole.
Two-bolt flange bearings are used in bearings having standard duty.
Such type of flange bearings’ housing is in three-bolt style. Three-bolt housing consists of three holes for the mounting.
Three-bolt flange bearing is placed at an angle of 120⁰ in a radial direction. It is also mounted on a triangular flange.
Three-bolt holes are placed at equal distance from each other.
Three-bolt flange bearings are used in bearings performing light duty.
Flange bearings are also made in four-bolt form. Four-bolt flange bearing housing has four holes for the mounting.
Four-bolt flange bearings are placed in a radial direction to each other surrounding the central bearing axis load.
Four-bolt flange bearings are in a form of circular (round) and square shaped.
Four-bolt flange bearings are used in bearings performing heavy duty.
What Are Bronze Flange Bearings?
Flanges in the flange bearings provide you with strength and rigidity even in a harsh environment. Such bearings play an important role in mounting. Flanges combined with the bearings carry the loads.
Let me inform you about bronze flange bearings.
Basically, bronze is a combination of tin as well as copper along with the additives such as nickel, zinc and aluminum which are vital for the metallurgical material.
Bronze flange bearings are stiffed in nature. Bronze flange bearings can perform better without regular maintenance.
Bronze flange bearings have a long bearing life and such bearings provide a good resistance to corrosion, shocks, wear and vibrations.
Bronze flange bearings offer a less friction when exposed to metal.

What Is the Importance of Bronze Flange Bearings?
Bronze flange bearings provide a greater wear resistance and are ideal for industrial equipments. Bronze flange bearings need no maintenance like other ordinary flange ball bearings.
Bronze flange bearings can operate well when a greater amount of load is applied and with less speed.
Bronze flange bearings are found in food processing equipments, motor pumps, automotives and in modeling of injections.
How Much Load can Flange Bearings Withstand?
The factor which is noticed when selecting a flange bearing is based on the amount of load applied.
Flange bearings can withstand little amount of thrust or axial load.
Such load for flange bearing is stated as a maximum load or pressure which is given to the shaft in the direction of axis either in parallel or same way.
Radial load of the flange bearing is stated as the maximum amount of load or pressure which is given to the shaft in a radial direction (perpendicular). It is also named as over-hung load.
Flange bearings can carry mostly radial load.
If the axial load is smaller than the radial load, select your bearing on the basis of radial force.
If the radial pressure and thrust load is equal then select your flange bearing on the basis of total of both load magnitude as equivalent to radial load.
What do you know about Maintenance-free Flange ball bearings?
Maintenance-free flange ball bearings consist of balls and are widely used in things which need them to be locked in the bearings. Such maintenance-free flange ball bearings are used in mounting. These bearings are shielded to restrict the contaminant particles from entering.
Types of Maintenance-free Flange Ball Bearings
- Flanged deep-groove shielded ball bearings
This type of flange ball bearing consists of flange and seal on a single or both sides. It is also present in stainless steel or glass balls in them.
- Flanged deep-groove ball bearings (Fixed)
Such type of flange ball bearing consists of housing with two-bolt holes. It has low precision fixtures for handling. Stainless steel balls are required in these bearings.
- Flanged ball bearing (Pivoted)
This kind of flange ball bearing offers a compensation for misalignment of the shaft. It also has two or four-bolt mounting holes.
Is Flange Bearing self-lubricating or Not? Explain.
Flange bearing is a maintenance-free and self-lubricating bearing that is it does not require any external lubrication. Such bearings have a PTFE liner lubricant or a silicon or graphite lubricant.
External ring of the flange bearing is made of polymer plastic, stainless steel, bronze steel or chrome steel.
In self-lubricating flange bearings, polymer sealing of the flange bearings prevent the dirt from settling in the bearing and do not causes friction and wear of the bearings.
