RunRight® Motor Base Product Information

RunRight elastomeric tensioning motor bases utilize a rubber suspension unit as a pivot mount. The rubber suspension unit continuously compensates for belt stretching, hopping, fluttering and excessive pull when a drive is started. RunRight tensioning motor bases are the ideal tensioning solution for all belt drives from about 1/2 to 700 HP.

Please do not hesitate to call or ask for help, should you have any question in selecting or installing a RunRight tensioning device. Lovejoy is here to help!

The following are just three classic examples of how RunRight™ motorbases can help a belt drive system run smooth.

Absorbing Peak Loads – Designed specifically for starting and moving a loaded belt, absorbs the impact of material loading and provides stability for proper alignment.

 
Energy and Cost Savings – Maintenance-free tensioning motor base provides constant torque transmission and less energy consumption increasing the life of the drive system.
Quiet Torque Transmission – In a shrouded application, the motor base provides quiet torque transmission while continually tensioning the belt.

The RunRight Motor Base is supplied with its mechanical pretensioning device at the ideal calibration of the relevant belt tension, based on the belt suppliers’ test force recommendations. Common V-belt sizes and the recommended deflection forces can be found in the motor base section of the full RunRight product catalog.
