Rubber Couplings  PC40-5 Excavator Centaflex-A coupling 16A

Product Description


1.  Material options for H series and A series Couplings

H series coupling we produced is made of Hytrel. It has elasticity like that of rubber. It is excellent in absorbing vibrations and shocks. It also excels in resistance to heat, low temperature and oil.


Input and output can be connected and disconnected easily merely by moving axially. By using a unique claming mechanism, mounting in a spline shaft is possible. Hub and spline shafts are completely fixed by using a clamping hub of the mechanism. No fretting wear is caused.


“A” Series coupling has two types, bolt mounted type (O0) and bayonet mounted type (S0).

Motive power is transmitted though a high elastic rubber. It is excellent in absorbing vibrations and shocks. Noise of machinery is also reduced. The rubber part is composed of a polygon rubber and aluminum insert inserted at the top, and each part is tightly attached by vulcanizing. Power transmission is accomplished by fixing the rubber body in the hub and flange hub in a radial direction and axial direction respectively by bolts.
