An integral part of many Hilliard motion control products is our roller-ramp design. The use of hardened cams and precision-machined rollers maximizes service life. There is almost no wear during freewheeling operations because rollers are free to rotate between the outer member and the inner cam. When the rollers are engaged, the load falls at random positions on the rollers. The result is superior service life and reliability. The Magna Torque is similar to the MT design except the cam surface is reversed allowing it to be used in multi-speed/dual drive applications.
