The BK17 fits the driven end of the ball screw and includes 2 MATCHED angular contact bearings (with C7 rating) to support the ball screw while resisting thrust loads imposed onto the screw The two bearings are clamped into the housing with 4 screws ensuring there is no lateral movement of the ball screw giving the greatest accuracy possible!

Acme Screws

ACME screw products are typically less costly than a ball screw and more tolerant to less-than-optimal operating environments Many ACME screws provide sliding element friction that prevents back driving eliminating the need for a braking device to account for the stored energy within a system
