Ball screw support bearings are critical to the life and productivity of a ball screw. These end-support bearings, which are found on every axis of almost all CNC machines in the world- should be changed regularly, enhancing production. Offered in a heavy preload, 60 degree contact angle, and stocked as universal flush ground face, making installation easier, no matter what the configuration. This ball screw bearing series is OEM packaged with preservation oil, promoting long life and inhibiting rust. We also cross or carry Barden and NTN ball screw support bearings.
