NTN Ball Screw Support Bearings

*NTN ball screw bearings are optimaized to support a ball screw.

The 2A-BST type incorporates the maximum possible number of small balls (compared with those of a standard bearing), has thicker inner and outer rings, and a larger contact angle of 60°. Thus, this type of bearing boasts greater axial rigidity. Additionally, since balls are used as the rolling elements, the starting torque of a angular contact thrust ball bearing is less than that of a roller bearing.

Angular contact thrust ball bearings for ball screws 2A-BST series

Side faces of BST type bearings are flush-ground to provide the same face height difference for both the front and back faces. As a result, bearings of the same part number can be freely combined into DB, DBT, DTBT configurations as illustrated in Fig. 13.2, and the adjustment for a relevant preload is no longer necessary.
