Ball Screw

The Ball Screw is a high-efficiency method of converting rotary motion to linear motion by using a recirculating ball mechanism between the screw shaft and the nut. Compared with a conventional sliding screw, the ball screw requires driving torque of one-third or less, making it ideal for saving drive motor power.

DIN Standard Compliant Ball Screw

DIN Standard Compliant Ball Screw

 

In the DIN standard compliant Ball Screw, balls under a load roll in the raceway cut between the screw shaft and the nut while receiving the axial load, travel along the groove of a deflector embedded inside the nut to the adjacent raceway, and then circulate back to the loaded area. Thus, the balls perform infinite rolling motion.

Support Unit

Support Unit

 

The Support Units are required to support the ball screw shaft.  They are available to suit any design adopted and are provided in six types.  Models EK, FK, EF, and FF, which are for standard Ball Screw assembly provided with finished shaft ends, and models BK and BF, which are standardised for ball screws in general. The Support Unit on the fixed side contains a JIS Class 5-compliant angular contact ball bearings adjusted to preload.

Lock Nut

Lock Nut

 

The lock nut is required for securing the fixed support unit to the ball screw shaft.  This provides easy fastening to the screw shaft thread. It includes a anti - loosening mechanism comprising a hexagonal socket-head setscrew and a set piece that prevents the lock nut from loosening so ensuring positive clamping.
