Formsprag Clutch introduces new CFB backstops for C-face motors
Formsprag Clutch recently announced the addition of the CFB family of backstops to their line of overrunning and backstopping solutions. The new CFB backstops are designed for use with C-face motors from 56C up to 365TC frames. The backstop input will cleanly interface with standard C-face mounting and the output provides the same pilot diameter, bolt circle and shaft configuration as a C-face motor in the same size.
The CFB’s backstopping torque exceeds more than 250% overload for motors in its frame size. The backstops provide load holding and back drive prevention for applications using C-Face motors. CFB units feature a centrifugal throw out design which enables the sprags to lift at speeds exceeding 665 RPM, eliminating wear and heat at high speeds. The backstops will automatically engage and hold the load at zero speed in the selected rotation.
CFB models require no external power, no adjustment, no control, no internal bearing and very limited maintenance. Eight models are offered with torque ratings from 673 lb.ft.
(915 Nm) to 1,734 lb.ft. (2358 Nm). All units are designed for horizontal or vertical mounting.
For over 50 years, Formsprag Clutch has been the recognized leader in designing, manufacturing, and delivering dependable long-lived overrunning clutches for a wide spectrum of industrial applications including conveyors & conveying equipment, food processing machinery, gear reducers, hoists & cranes, mining machinery, machine tools, paper converting machinery, packaging machinery, pumping equipment, and many other types of specialty machinery… worldwide.
