Spring Engaged Brakes – NEMA Frame

C-Face Mounted Friction Brakes for Power Off Holding

Function: Holding, Failsafe (Non-Cycling Applications)
Drive Arrangement: Motor to Gear Reducer (Gear Box)


  • Spring pressure compresses drive and friction discs to produce a fixed amount of torque.
  • The brake is released when energized with sufficient air pressure (see table below).


  • Brake is designed to mount between a c-face motor and gear reducer.
  • Not suitable for belt or chain drive (pulley or sprocket output) configurations.
  • Brake is designed for horizontal mounting. If vertical mounting is required, consult engineering.


  • Spring engaged brakes are designed for holding applications.
  • Maximum RPM varies by model and is listed on the PDF detail sheet (see table below). Consult engineering┬áif the intended application exceeds the listed maximum RPM.
