Product Description

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:

1. Standard type

2. Flanged outer ring

3. Extended inner ring

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

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