Description


Disc coupling is consisted of Hub, spacer and disc packs. Because the material of these is steel, the coupling has robust strength and can transmit heavy torque. And, the disc packs are made of stainless steel, flexible and restoring, and has main characteristics of the coupling.


[Features]

- No backlash and high torsional stiffness

- Ensuring long life

- The assembling and disassembling are availabel without dismantling other connected machinery.

- Safe even accidental

- Usable for high temperature and high speed.
