A torque limiter is a device that cuts off torque transmission when overload is applied. It is also called a safety-clutch. By preventing excessive rotation of the spindle, it prevents damage to the driven shaft and related equipment. TOK manufactures 2 types of torque limiters:
①Spring Type using friction / resistance
・Max. torque : 4kgf・cm
・Max. allowable rotation speed: 400min-1
・Life cycle time : 1 Mio. cycles
TLD4 series TLD7 series
②Magnet Type using magnetic force
・Max. torque : 0.6kgf・cm
・Max. allowable rotation speed: 2,000min-1
・Life cycle time : 10 Mio. cycles
TLEU series TLES series
