Zimmer Linear-Guide Braking Element – 35mm Bosch Rail (Air to Release)

The Zimmer Linear-Guide Braking Element (Part #R161934031) is an air-released brake built for 35mm Bosch Rexroth linear guide rails. It delivers precise motion control and secure holding by using spring force to engage the brake and compressed air to release it. Its steel and aluminum construction withstands repeated engagement cycles and heavy operational loads. The brake supports safety-critical applications by providing stable, mechanical holding whenever air pressure drops. Its compact profile, reliable performance, and maintenance-friendly design allow it to integrate cleanly into Rexroth linear guide systems.
