Deep groove ball bearings are among the most widely used rolling element bearings. They are used in numerous applications in machines and gadgets. They consist of an inner and outer ring with balls that complement the rolling between the raceways. The features of the deep groove allow the bearing to take radial and moderate axial loads in both directions. With several types available in the market, the NASR deep groove ball bearings made from carbon steel stand out due to their matchless precision, high load capacity, and low friction.

How Are Deep Groove Ball Bearings Assembled?

For the assembly of deep groove ball bearings, the inner and outer rings are precision machined to tight tolerances, ensuring a perfect fit for the rolling elements. Similarly, the balls that will be the rolling elements are carefully manufactured to the required size and surface finish. The bearing cage, responsible for maintaining the proper spacing and alignment of the balls, is stamped or molded to the precise shape and size needed.
The inner ring is first placed on a specialized fixture, and the balls are then carefully inserted into the inner ring’s raceway. The outer ring is then pressed over the ball complement, enclosing the rolling elements and completing the bearing assembly. The bearing cage is then installed, further ensuring the proper positioning and distribution of the balls within the bearing.
Finally, after performing noise, vibration, torque tests, and dimensional checks, the bearing is carefully packaged and preserved to protect it during shipping and storage. It is ready to be installed in a wide range of applications.

How to Install Deep Groove Ball Bearings?

Here’s how you can install these bearings correctly, ensuring optimal performance and longevity:

1. Clean the housing and the shaft.
2. Take measurements of the components to be fitted to avoid misfitting.
3. Assemble the tools required, such as a bearing puller and a press.
4. Select the right size and deep groove ball bearing for your system.
5. Wipe the shaft and housing lightly with clean oil to make it easy to assemble.
6. In the case of press fits, a bearing press is recommended to apply uniform force on the face of the bearing.
7. For sliding fits, the bearing should be slid carefully onto the shaft.
8. Make sure that the bearing is perpendicular to the shaft and the housing.
9. Make sure that the seat and the backrest are appropriately adjusted.
10. Fit any locks that may be needed, for instance, snap rings or locking nuts.
11. To increase the efficiency of the shaft, it should be rotated appropriately.

Whether you’re a manufacturer assembling these bearings or a technician installing them in machinery, attention to detail is paramount. Proper assembly ensures that each component works harmoniously, while correct installation prevents premature failure and maintains optimal functionality.
