Precise, Compact, and Powerful

FMCBENexen FMCBE Flange Mounted Clutch-Brakes Enclosed are designed for controlled starts and stops in hostile, dirty environments. The totally enclosed design prevents contaminants from interfering with operation of the units while keeping worn friction material from escaping into the environment. Flange mounts directly to C-face motors up to 20 HP and reducers. An optional foot mount is available for belt drive applications, and an optional input unit allows you to incorporate pulleys or couplings into your application.


Stopping, holding, cycling and indexing, jogging and inching, connect/disconnect, accurate positioning, controlled acceleration, controlled deceleration, high inertia start or stop
