Warner Electric 5370-170-212 Spring Set Brake

SERIES DESCRIPTION

The Warner Electric SSBM Series (EM/ERS) Spring-Set Brake Modules are NEMA C-face compatible units designed to perform reliable static holding as well as occasional emergency stopping functions. Operating on a power-off, spring-applied engagement principle, internal springs compress the friction disc against the end plate when electrical power is removed. Applying DC voltage energizes the magnet coil, overcoming spring force to electrically release the brake and allow free shaft rotation. Fully assembled and preburnished at the factory, they are easy to install and require no maintenance adjustments.

FEATURES

• Fail-Safe Holding: Spring-set clamping provides positive holding torque in power-off conditions and emergency stops.
• NEMA C-Face Compatible: Direct mounting to standard NEMA C-face motors and gearboxes for seamless retrofits or OEM machinery.
• Preburnished & Factory Assembled: Ready to install right out of the box with zero initial adjustments required.
• Eco-Friendly Friction Material: Features high-torque, lead-free, and asbestos-free friction facings.
• Rapid Response: Delivers crisp apply and release times for precise holding and positioning control.

SELECTION PROCEDURE

1. Step 1: Match NEMA Frame Size—Select module size based on prime mover or reducer frame requirements (Size 180 fits 143TC/145TC frames).
2. Step 2: Verify Holding Torque & Inertia—Select required holding torque (34.0 lb. ft.) and check emergency stop limits against system load inertia and operating RPM.
3. Step 3: Choose Voltage & Control—Select coil voltage (90 VDC) and pair with a compatible Warner Electric non-adjustable power supply or control.
