The Posistop oil shear coupler brake from Force Control Industries is an ideal replacement for electric brakes often found mounted on the back of a special brake motor. Oil Shear Technology is the function of a boundary layer of transmission fluid in shear between the friction disc and drive plate. As the parts come together the fluid under shear will transmit torque between the two parts as well as absorb heat. This heat is then taken away from the friction surface to the housing to be dissipated.
- Mounts to the working end of a standard C-face motor eliminating the need for a special brake motor; the motor can then be used for non-brake applications, reducing motor inventory
- May also allow use of a fan cooled motor
- Teflon liners on all piston sealing areas for smooth response and long service life; eliminates o-ring breakage
- Bearings are oil lubricated
- Solid cast iron or aluminum totally enclosed housings protect the brake from adverse environments including dust, dirt, and moisture
- Unique collet design hub connection eliminates key and keyway failures and ensures easy disassembly
- Air actuated, or hydraulically actuated
- Sizes and torques for motor frame sizes 56 to 320 and torque ranging from 6 to 450 lb.-ft.
- Can be used horizontally or vertically
- Require a small amount of air up to 80 psi
- Available in other configurations such as brake motors, through shaft, and flange mounted
- Can be spring set, air release or air set, spring release
