Self-adjusting motorbases

The Rosta element is incorporated in a motor mounting plate. The motor bearings and belt or chain are relieved by the drive springing along by high starting torques or inertia. The lifetime is significantly prolonged and realizes energy savings of up to 20%.

Fully maintenance-free tension system. No need for periodical compensation of belt elongation.
Less downtime because the belt high inertia is relieved. Replacing the belt is easy by releasing the pretension of the motorbase.

Motorbase available in 5 sizes. Ideal tensioning answer for all belt drives from 0.75 kW up to 250 kW nominal power rating.

The Rosta motorbases are easy to install. Each type has a separate installation manual available in which the ideal position is described.

  • Quick response, short lines
  • Renowned manufacturers
  • Profound product knowledge
  • High reliability

We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.

In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
