Dynamic behaviour 

The combined elasticity and damping capacity of the rubber bushes reduces both shock loads and critical speed. Compressed by an increasing torque, the bushes become stiffer due to the scalloping, thereby reducing the resonance effect at critical speeds.

Arrangement PB: with brake drum
This version is made up of two parts: 

• the standard female hub,
• a male hub with a brake drum.

Arrangement PD: with brake disc

This version is made up of four parts:

• the standard female hub,
• an intermediate pin holder,
• a brake hub,
• a solid brake disc clamped between the latter two parts (ventilated brake disk also available on demand).

This State-Of-The-Art design ensures highly reliable braking in harsh conditions.
Our PENCOflex PD couplings meet high demanding security standards for haulage, cranes and elevators
