RUKO KEB-HSS-Mod.110-32.0mm Spring-Applied Electromagnetic Brake

Industrial machinery requires reliable holding and emergency stopping without the risk of unintended movement. The RUKO KEB-HSS-Mod.110-32.0mm is a spring-applied electromagnetic brake that engages when power is removed, delivering a static friction torque of 160 Nm to keep shafts securely in place.

Who is it for

This brake is built for machine builders and maintenance teams integrating or servicing flange-mounted braking systems on motors, gearboxes, and other rotating equipment. It suits applications where a dry-running, electrically released brake is needed for holding and emergency stop functions.

Main features

• Spring-applied, electrically released design for fail-safe holding
• 160 Nm static friction torque for demanding loads
• 32.0 mm H7 bore diameter for direct shaft mounting
• Rated for 205 V DC operation with 45 W power consumption
• Dry-running with two friction surfaces for consistent performance
• IP54 protection against dust and splashing water
• Thermal class F insulation for operation up to 155°C
• Fast response: release and engagement times below 50 ms

Tips

Verify the air gap during installation and after break-in to maintain consistent torque. The brake is flange-mounted; ensure alignment with the shaft to avoid uneven wear. For emergency stop applications, confirm that the power supply can interrupt the coil circuit within the required time.
