Choose Genuine
Replacement Parts

If quality and safety are important to you, insist on genuine replacement parts for your Industrial Clutch, Wichita Clutch, and Twiflex clutches and brakes. With genuine replacement parts, you get better performance, longer life, safer operation, and peace of mind.
All genuine replacement parts are manufactured in Altra’s U.S. and European production facilities and under the company’s strict guidance and control.

Backstop Rebuild Program

To extend the life of a long-serving backstop, Marland
and Formsprag customers can contact their local Altra or Warner Electric sales office to locate trained and
authorized repair and/or rebuild facilities.

Rebuilt backstops from Altra often cost 30% less than a new unit, and come with the same full warranty as new units. Additionally, only authorized repair facilities can promise 100% genuine replacement parts and ensure the safe operation of your rebuilt backstop.

The difference is not just cosmetic.

All internal components– sprags, energized springs,
retainer, bearings, seal and hardware are refurbished or replaced to new performance standards. The inner and outer races are ground to specifications noted below so that no wear patterns remain.
