Aluminum flexible jaws or stainless steel DJ coupling with keyway spider shaft coupling

 1.Compact size and small inertia.

 2.The coupling engineering plastics as elements ,with cushioning, vibrationreductionand wear resistence, the working temperature is -35-+80.

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