Rubber Joints

Rubber Block for Koppers Joints

Characteristics

Koppers joints are prepared from high quality natural rubber and neoprene. They are used as a coupling in electric motors. Generally it has lower torsional stiffness than a flexible steel disk coupling, and provides additional cushioning. Cushioning limits the dynamic torque when operating near resonance.

– The maintenance and operation costs are low compared to the couplings normally used.

– The needed lubrication is low or almost zero, so the service requirements and test failure are non-existence.

– Resistant to ozone and to most chemical oxidants.

– High deformation resistance.

-Lifetime of 8 months or more.

– Cylindrical rubber block with high resilience to strain to joint type CB: coupling cushioning

Materials

– Mix of high quality neoprene and natural rubber vulcanized according to ASTM standards.
