About BLM Automatic Clutch

At BLM Automatic Clutch , we produce two main designs. Our Four Block Series clutches (1/4-50 HP) find application in chippers, tampers, concrete pumps, mortar mixers, conveyors, and refrigeration. Our Six Block Series (up to 3,000 HP) are used in large industrial and varied commercial applications such as crushers, fans, pumps, centrifuges, brake drums, and textile machinery.

Whatever your application, if it requires starting assistance and/or overload protection, we can help. We also provide customized pieces for single use products or “one of a kind” specialized applications. We are happy to work with you to develop a prototype for your unique application.

Established in 1932, BLM has been designing custom high-quality products for decades. You can trust in our 85 years of experience in designing and manufacturing centrifugal clutches for applications of all kinds, including Military, Public Works, Chemical and more.
