High-speed design bearings, BTM series
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.
According to the ISO definition, BTM series bearings are radial bearings because they have a 30° or 40° contact angle. However, since these bearings are only intended to accommodate axial loads, only their basic load rating in the axial direction is listed in the product table.
