Stearns 105672105QF Motor Brake

Stearns 105672105QF is a spring-set holding brake (ERS) designed to mount to a motor’s C-face and operate on 230/460 VAC single‑phase power. The unit is compatible with motors in the 143TC/145TC/NEMA 56C family and mounts to the motor’s C-face, using a 5/8 in shaft bore; the brake housing measures 6.88 in outside diameter and 4.91 in overall length, delivering a static torque of 6 ft‑lb at up to 5,000 RPM. The 230/460 VAC coil is listed with automatic reset, providing fail‑safe braking (engages when power is removed) to hold the driven load in place. Typical applications include conveyors, machine tools, and packaging equipment where controlled stopping and load holding are needed with the motor running, or where a load must be held stationary during power loss.
