RUKO KEB-HSS-Mod.55-45,0mm veerdruk-elektromagneetrem, 45 mm boring, 100 Nm, 24 V DC

In industrial machinery, holding and emergency stop functions demand a brake that engages reliably when power is cut. The RUKO GMBH KEB-HSS-Mod.55-45,0mm is a spring-applied, electromagnetically released brake from the COMBISTOP HSS series, engineered for flange mounting and a 45 mm bore diameter.

Who is it for

This brake suits machine builders and maintenance engineers who need a robust holding brake for servomotors, gearboxes, or other rotating equipment where safety and precision are critical.

Main features

• Spring-applied, electromagnetically released design ensures fail-safe braking on power loss.
• Static friction torque of 100 Nm provides strong holding force.
• Rated for 24 V DC operation with 0.8 A current and 19 W power consumption.
• Maximum permissible speed of 4000 rpm accommodates high-speed applications.
• Nominal air gap of 0.2 mm for consistent performance.
• IP54 protection class guards against dust and water splashes.
• Insulation class F allows operation up to 40°C ambient temperature.
• Asbestos-free friction lining and cast iron/steel housing for durability.
