What Formsprag Clutch does
Formsprag Clutch is a Warren, Michigan-based designer and manufacturer of overrunning clutches, backstops, bi-directional clutches and clutch couplings, founded in 1946 as a spinoff of the Gear Grinding Machine Company. The company specializes in sprag and ramp & roller type clutch technologies protected by six patent families including the Free-Action retainer, PCE sprag profile, Centrifugal Throw-Out sprag profile, Formchrome surface treatment, Reverse-Locking and Form-Lock bi-directional backstop designs. Its 800+ SKU catalog spans general-purpose, special-purpose, backstopping, modular building block, clutch coupling and electromagnetic clutch/brake products supporting torque capacities up to 500,000 lb.ft.
The business sells primarily to industrial OEMs and end users across aerospace & defense (including VTOL/eVTOL propulsion systems, helicopters and satellites), mining & aggregate, material handling, power generation (including nuclear), oil & gas, food & beverage, wastewater, and amusement ride applications. Manufacturing is consolidated at the Warren, Michigan plant, which is also the sole authorized rebuild facility, operating an emergency 24-hour breakdown program for air-freighted units. Go-to-market combines direct field sales with technical sales engineers, an inside sales channel at 1-800-927-3262, the OrderNet B2B e-commerce portal, and authorized literature distribution; pricing is quote-based rather than list-published.
Formsprag operates as a wholly-owned subsidiary of Regal Rexnord (the diversified industrial motion and power transmission conglomerate, formerly Altra Industrial Motion), with sister company Stieber Clutch in Germany providing complementary ramp & roller coverage. The Warren facility holds AS9100D and ISO 9001:2015 certifications (SGS-issued, ANAB-accredited). Sources report no disclosed revenue figures, headcount in the 51-100 range, and an installed-base driven mix of new unit sales, rebuild/overhaul services priced at approximately 30% of new list price, and aftermarket accessories such as axial restraint keys, OSHA covers, torque arms and oil reservoirs.
