TS7Z series precision lock is suitable for the joint between long shafts and hubs and can transmit bigger torque.They can replace couplings in some mechanical transmission if the shaft diameter and precision are the same.

The working principle of TS7Z is as following:under the pressure of tightening bolts,two tightening rings with inner taper surface press the inner ting with outer taper surface and then make it contract to tighten the hubs and shafts.The emerged radial pressure and friction force make the hubs and shafts join together.

Features:

1.Simple structure,easy to assembly and disassembly

2.Low cost,convenient to use
