Hysteresis brakes
PHT-D hysteresis brakes operate by double permanent magnets and have no wear, making them suitable for constant tension applications as well as torque limiting applications.
Features & benefits
Torque ranges from 0 to 62 lb-in. in 9 models
Deliver torque regardless of slip speed
Smaller models have maximum speeds of 3,600 rpm; larger models have maximum speeds of 1,800 rpm
Can be adjusted individually within given torque range

Lift truck brake
LWB hydraulic-actuated, full-circle disc brake uses center hub of wheel rim as a friction surface to eliminate need for bolt-on friction rotors.
Features & benefits
High-strength ductile iron and asbestos-free friction material for reliable stopping and long life
Secondary seals protect piston seals; deflector plate prevents entanglement of foreign objects
Piston seals minimize fluid displacement and come in a variety of materials
Act as a spindle and bearing support for load wheel; minimizes temperatures as wheel's thermal mass absorbs heat
