The higher the hardness of the rubber is, the harder the rubber is, and the higher the hardness is adopted for the shock-absorbing rubber pad, so that the shock-absorbing rubber pad can bear larger load and can give consideration to the shock absorption effect and the load capacity.

Further, the rubber bushing is made of an annular rubber material with the hardness of 50 degrees. The rubber bushing is made of harder rubber material, and has good wear resistance and silence.
