RUKO KEB-HM-26,0mm Electromagnetic Spring-Applied Brake

Industrial machinery often needs a reliable way to stop rotating shafts quickly and hold them securely when power is cut. The RUKO GMBH KEB-HM-26,0mm is an electromagnetically released, spring-applied brake that solves this problem by engaging automatically when voltage is removed, providing fail-safe braking for a 26 mm hollow shaft.

Who is it for

This brake is built for machine builders, retrofitters, and maintenance teams working with conveyors, packaging equipment, hoists, or any drive system where a power loss must result in immediate shaft holding. It suits applications requiring a compact, robust brake with a 100 Nm static friction torque.

Main features

• Spring-applied, electromagnetically released operation for fail-safe holding
• 26.0 mm bore diameter for hollow shaft mounting
• Static friction torque of 100 Nm
• Rated voltage of 205 V DC with 40 W power consumption
• IP54 protection against dust and splashing water
• Insulation class F (155°C) for reliable thermal performance
• Asbestos-free friction lining
• Terminal box electrical connection
