Type DSR 2.5 to 12,000 Nm

Roller type torque limiters transmit high torques in compact dimensions. They suit operation in dry or oil environments and will synchronise input to output on re-engagement. They transmit torque and limit equally well in both directions. Axial movement on overload can be detected with a limit switch to give a warning signal.

In operation torque is transmitted by a number of rollers that sit in grooves and are spring loaded. On overload the rollers rise out of the grooves and transmitted torque falls to a low level. The limiter will try to re-engage once every revolution once the overload is removed.
