Rotastep

Features

Rotastep is a pneumatically controlled clutch/brake unit that offers flexible, high output via a simple design giving long operating life.

Its associated range of electronic controls meets market requirements on functions such as counting, sensing, activating, de-clutching and compensating etc. The modular construction enables the customer to select precisely those functions required for his production machinery.

The use of compressed air avoids any undesirable magnetic field effects and gives variable torque control. By adjusting the supply pressure the torque can be varied as necessary within the torque range of each Rotastep unit.
