Reduce downtime and
protect your drive, with Howdon torque limiters and disc brakes

Designers and manufacturers of torque limiters since 1977

Howdon Power Transmission have been involved in the design and manufacture of torque limiters for over 40 years. We invented the revolutionary Wedgegard Shearpin Torque Limiter in 1977 to address demand for a simple solution to torque overload protection.

A torque limiter is a device that protects mechanical equipment, such as conveyors and pumps, from damage by jamming or overload.

During these challenging times, as countries around the world have shut-down due to COVID19, Howdon Power Transmission have remained operational as an essential supplier to the manufacturing industry. We are following all safety protocols for our staff, some working remotely, to give the best support to your business. There will be, however, some unavoidable disruption from time to time in the standard of service you have come to expect from us but we continue to work hard to meet customers requirements in an evolving situation. Thank you and stay safe.

Putting our torque limiters to the test

We have invested significantly  in custom built static and dynamic test rigs to ensure that the Wedgepins break at their rated torque and within  tolerance.  This gives customers confidence in Howdon Wedgegard products.
