MDB modular clutch-brakes are ideal for more demanding applications. They offer more torque and open design offers higher thermal ratings. Flange mounts directly to NEMA C-face motors up to 10 HP and reducers. Offers true neutral position (no clutch or brake engagement). A drip proof sealing kit is available for wet applications. Optional foot mount and input units are available for belt, chain and coupling, drive applications. In high cycle rate applications where the MDB is connected to a reducer that would use the smaller 625 and 875 sizes the FMCBE clutch brake series with the locking key feature should be considered due to potential output shaft key or keyway problems.
