Spring Applied Electric Brakes

Product Announcement from Hilliard Corporation (The)

Hilliard Spring Applied Electric Brakes provide positive stopping and reliable holding of rotating devices on demand. Every time.


Spring-engaged when current is interrupted and electromagnetically released when voltage is applied, these brakes are designed for maximum flexibility and long, dependable service.

•Each brake features a heavy-duty friction disc for long service life, a fully epoxy-potted coil and durable springs

•Torque is transmitted through hardened dowel pins rather than through bolts

•An easy-to-adjust wear bolt compensates for friction surface wear and extends brake life

•Available in four standard sizes and a wide range of coil voltages and torque ratings

•Most commonly used on escalators, robotics, forklifts and similar equipment

Design Features:

•Conservatively rated helical springs

•Fully epoxy-potted coil

•Solid friction disc

•The number and force of springs can be varied

•Available in 6 to 240 VDC

•Torque ratings from 7.5 to 4,500 lb.-ft
