It is a traditional method to tighten the fixed shaft at an interval of 90° between the two positioning screws.Since the tip of the screw contacts the shaft, it may cause damage to the shaft or difficulty in installation and removal.

Keyway fixed

This type is the same as the fastening bolt, it is a fixing method, suitable for high torque transmission.In order to prevent axial movement, the fastening bolt type and the clamping type are usually used.

Clamping screw fixed

The tightening force of countersunk bolts shrinks the slits and firmly grasps the shaft, which is easy to fix and disassemble, and will not be damaged by thousands of axles.

Expansion sleeve fixed
