Torque Limiters

Torque Limiters

Never wear down with this unique magnetic Torque Limiters
torque

These are mechanism components that interrupt movement with a specified torque

Magnet type: no contact torque limiters based on the hysteresis torque of magnets
Coil type: contact type of torque limiters that generate torque using the frictional resistance between a coil and the outer surface of a sleeve

TOK’s extensive experience using plastic materials in its anti-friction products assisted in the development and production of these torque limiters. Compact, lightweight, and cost-effective, TOK torque limiters are essential components of paper and ribbon feeding mechanisms in today’s printers

Applications
Copy machines, fax machines, printers, and other automated equipment

Features
1. Variable torque selection
2. Compact and lightweight


TLE Series (Magnet type)

FEATURE
・Fluctuations of torque due to rotational speed changes are reduced.
・Fluctuations of torque due to temperature and humidity changes are reduced.
・Fluctuations of torque in CW and CCW are reduced.
・Minimal torque difference between starting torque and dynamic torque.
