What’s Torque Limiter?

Torque limiter is a device that cuts off torque transmission when overload is applied. It is also called safety-clutch. By preventing excessive rotation of the spindle, it prevents damage to the driven shaft and related to equipment.

TOK manufactures 2 types of torque limiters :
l  Spring Type using friction / resistance
Ø  Max. torque : 4kgfcm

Ø  Max. allowable rotation speed : 400min-1
Ø  Life cycle time : 1 Mio. cycles

TLD4 series                                       TLD7 series

l  Magnet Type using magnetic force
Ø  Max. torque : 0.6kgfcm
Ø  Max. allowable rotation speed : 2,000min-1
Ø  Life cycle time : 10 Mio. cycles

TLEU series                                       TLES series

Application example

Sunshade of child seat                     Belt-winch
