High-speed design bearings, BTM series
Bearings in the BTM series (fig. 1) consist of two non-separable single row angular contact ball bearings arranged back-to-back. They are designed to accommodate axial loads in both directions. When the inner rings are pressed together, preload within a predetermined range will result.
These high-speed design bearings are available with two different contact angles:
- a 30° contact angle, designation suffix A
- a 40° contact angle, designation suffix B
Bearings with a 30° contact angle can accommodate higher speeds while bearings with a 40° contact angle are more suitable for applications that require a higher degree of axial rigidity.
