RunRight® elastomeric tensioning motorbases 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 motorbases are the ideal tensioning solution for all belt drives from about 1/2 to 700 HP.
RunRight RCM C20 and RCM C30 Motorbases are designed for smaller belt drives using an electric motor with 1/2 to 5 HP. They are used on 90S to 112M IEC frame sizes and 143T to 184T NEMA frame sizes. They are manufactured with all steel components and Tensys™ 30 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
RunRight RCM C38 Motorbases are designed for smaller belt drives using an electric motor with 3 to 20 HP. They are used on 132S to 160L IEC frame sizes and 213T to 256T NEMA frame sizes. They are manufactured with all steel components and Tensys 30 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
RunRight RCM C50 Motorbases are ideal for electric motors from 3 to 75 HP. They are used on 132S to 225M IEC frame sizes and 213T to 365T NEMA frame sizes. They are manufactured with all steel components and Tensys 30 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
RunRight RCM C70 Motorbases are ideal for electric motors from 15 to 200 HP. They are used on 180M to 280M IEC frame sizes and 284T to 445T NEMA frame sizes. They are manufactured with all steel components and Tensys 30 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
RCM C70 designs with a "*" are only recommended for grizzly feeder applications.
RunRight RCM L100 Motorbases are ideal for electric motors from 150 to 700 HP. They are used on 315S and 315M IEC frame sizes and 447T to 5808 NEMA frame sizes. They are manufactured with all steel components and Tensys 30 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.
