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.
