Manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.

Single-Row Deep Groove Ball Bearings


Pressed Steel Cages


Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.


In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.


For big deep groove ball bearings, machined brass cages are used.


Machined cages are also used for high speed applications.


Extra Small Ball Bearings and Miniature Ball Bearings


Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:

Standard type


Flanged outer ring


Extended inner ring


Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.


Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed. 

Maximum-Type Ball Bearings


Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. BL2 and BL3 types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 62 and 63 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.


Magneto Bearings


The inner groove of magneto bearings is a little shallower than that of deep groove bearings. Since the outer ring has a shoulder on only one side, the outer ring may be removed. This is often advantageous for mounting. In general, two such bearings are used in duplex pairs. Magneto bearings are small bearings with a bore diameter of 4 to 20 mm and are mainly used for small magnetos, gyroscopes, instruments, etc. Pressed brass cages are generally used.
