Airflex Clutches And Water-Cooled Brakes
Description
Constricting Clutches and Brakes
Drum-style products that when pressurized, expand radially inward
forcing their friction shoes against an outer cylindrical drum surface. Use CB for power transmission applications, CM for marine, and VC for heavy duty equipment. The new High Energy Ventilated Clutch features metallic friction linings to sustain more torque and extend slip times for improved efficiency and extended driveline component life.

Water-Cooled Brakes
There are 3 Water-Cooled brake models: WCB, an air-applied brake; WCS, a spring- applied clutch or brake; and WCSB, a combination water-cooled and air-cooled brake that provides both high energy absorption for tensioning and fail-safe braking for holding and e-stop.

Air-Cooled Disc Clutches and Brakes
Featuring favorable torque-to-size ratios and low-inertia friction disc
assemblies. The DB and FHB brake types are spring-applied, pressure- released multiple disc units. luben@youlongpetro.com www.youlongpetro.com The DC type is a pressure-applied multiple disc unit that can be used as a clutch or brake.

Torque Limiting Couplings
Designed to withstand the torque spikes found in the most demanding applications of Variable Frequency Drives. luben@youlongpetro.com www.youlongpetro.com The TLC is engaged through air pressure at 0 RPM and continuously monitored
by electronic controls. When a system overload is detected, the TLC automatically disengages.
