DC Electromagnetic Brakes Model: QBSS-C
DC Electromagnetic Brakes Model: QBSS-C
  • Compliant with JEM1120 Standards
    These products conform to JEM1120 "DC electromagnetic brakes for DC electric motors of auxiliary rolling equipment and cranes".
  • Wide Range of Applications
    These products demonstrate superior reliability even under punishing conditions of use. In addition to use with auxiliary rolling equipment and cranes, they can be used across a range of industries. They are ideal for stopping and holding large capacity electric motors with frequent use.
  • Lubrication Free
    The pin holes in each part of the brake use oil-less bearings (dry metal), eliminating the need to lubricate the pins with grease, and improving maintainability.
  • Reduced Actuation Shock
    A sealed cover is provided around the electromagnet gap, creating an air damper mechanism that uses the negative pressure around the gap when the brake is actuated. As a result, the actuation shock is reduced, and the impact on the rigidity of devices used in tandem (namely, shafts of motors and machines) is ameliorated.
  • High Reliability
    Even under punishing conditions, such as continuous or highly frequent use (actuation frequency of 600 times/h, utilization ratio of 40%), these products can be used.
  • Environmental Measures
    Asbestos-free linings are equipped as a standard feature.
