What Is a Bearing Holder?
A bearing holder is used in various machines to support bearings in the correct position to receive the load and the rotation of the rotating shaft.
A bearing holder is attached to the body of a machine and holds the bearings by fitting them. The bearing holder that holds the bearing must be designed to match the size of the load that the bearing is subjected to.
Normally, the size of a bearing determines the amount of load it can support. A bearing holder is also designed to have sufficient rigidity depending on the size of the bearing they can hold.
Uses of Bearing Holders
Bearing holders are mainly used in industrial machinery. The part that holds the bearing must have sufficient rigidity to withstand the load that the rotating shaft receives. In addition, details such as the surface roughness of the bore and the size of the corner radii must also be considered.
The use of bearing holders simplifies the design and manufacturing of the housing portion that holds the bearing. Normally, bearing holders are mounted as a single or double bearing holders when the bearing to be fixed is a deep groove ball bearing.
If the bearing to be fixed is an angular contact bearing, it can be used with a back-mounted double bearing or with an additional deep groove ball bearing mounted in the bearing holders.
Principle of Bearing Holders
Bearing holders have the following functions:
1. Rigidity
Even if the rotating shaft is subjected to load, the rotating shaft must remain in position and maintain smooth rotation. If the rotating shaft has gears, the correct gear meshing cannot be maintained if the rotating shaft is misaligned. If the rotating shaft is not held correctly, it is likely to cause loud noises or, in the worst case, damage the gears.
2. Positional Accuracy
In most cases, bearing holders are screwed to the body part of the machine. If the positional accuracy of the bearing holder's screw holes and bearing holding holes is poor, the rotating shaft cannot be held in the correct position.
The size of the housing hole, which is the part that holds the bearing, is also important. If the housing hole's inner diameter is too large for the outer diameter of the bearing outer ring, there will be rattling between the bearing and the housing. The housing bore of the bearing should be finished to a tolerance grade of about H7 for a clearance fit.
3. Heat Dissipation
Heat dissipation is also important, especially when the rotating shaft is subjected to high loads and high-speed rotation. Bearings may generate a lot of heat due to high load and high-speed rotation. It is an important role of bearing holders to dissipate the heat generated by the bearing to the outside.

How to Use Bearing Holders
Although bearing holders are usually designed so as not to impair the performance of the bearings, they will not fulfill their function if they are not used correctly. One important factor is how the bearings are mounted. There are several ways to mount bearings, such as flange seizures, retaining rings, and free-running bearings, so it is necessary to select one that best suits the application.
- Flange Holder
The flange attached to the bearing holder holds the bearing and fixes it in the axial direction. Use a flange holder for applications where axial movement is not desired. - Retaining Ring
A groove is made in the housing and a ring, called a retaining ring, is attached to the groove to prevent the bearing from coming loose. This ring is used when no force is applied in the axial direction and a slight axial rattling is not a problem. - Free-standing
No restriction is provided in the axial direction, allowing the bearing to move freely. This method is used to support the free end of a ball screw.
