1.Compact size and small inertia.

 2.The coupling uses engineering plastics as elastic elements , with cushioning ,vibration reduction and wear resistance, the working temperature is -35-+80 and maintenance free.

 3.The elastomer is limited by convex clawblock,which can avoid internal deformation caused by impact and external deformation caused by centrifugal force. The large concave surface of the convex claw makes the surface pressure on the involute tooth very small,even if the tooth bears overload, the tooth will not wear or deform.
