Rolling Motion Industries has released two new traction drives: the MAR-17-2-2.1 and the MAR-23-2-2.1.

These highly efficient 2-Way gearless traction drives with only six moving parts use an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12.

The drives have demonstrated an up to 84 percent reduction in motor torque ripple when measured at the output shaft of the motor and then measures at the output shaft of the traction drive. 

The MAR17-2-2.1 is designed for speeds to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-2-2.1 is rated for 3600 rpm with 20 to 30 in/lbs of torque.

  • Generate up to 72% less heat after 24 hours of continuous operation.

  • Create up to 38% lower dB at 3000 rpm than conventional gearboxes.

  • Typically last three times longer than conventional gearboxes.

  • No slippage or lost motion between the input and output shafts.

  • Operating at temperatures that are lower than a motor’s.
