Product Description

Since 1953, Magtrol has created literally thousands of special and modified brake and clutch designs to help solve specific application problems for our customers.

Common Specials and Modifications Include:

  • Non-Standard Coil Voltages
  • Special Shaft Configurations: keyways, flats, holes, hollow
  • Extended Shafts
  • Forced Air Cooled Brakes
  • Adjustable Permanent Magnet Brakes
  • Speed Pickups
  • Special Mounting Configurations
  • Nonstandard Lead: material, lengths, location
  • Higher Torque Devices
  • High Speed Units
  • Brake/Clutch Combinations
  • Dust Covers

Specifications

Although intended for coupled service, moderate overhung loads can be tolerated, depending on such operating characteristics as speed, weight, and center of gravity of load. Care should be taken to make certain that the shaft is properly aligned. Couplings should be of proper size and flexibility to adequately protect bearings from undue stress and shock loading.

Base Mount

Base mounting is standard on all HB-840 and HB-3500/HB-3500M double brakes. Base mounting is also available as an option on 450 and 1750 oz·in single brakes.
Base Mount Dimensions All other dimensions per standard brakes.

Ordering Information: An HB-450 with a base mount is an HB-451 and an HB-1750 with a base mount is an HB-1751.

Extended Shafts

Higher Torque Capacity

It is Magtrol’s policy never to overstate the capabilities of our products. As a result, our brakes are conservatively rated. Higher torque values (15-25% above rated torque) are typically available from each brake, depending on the brake being ordered. In addition, special designs capable of producing even higher torques are available. Contact Magtrol for more information.

Mounting Options

Although intended for coupled service, moderate overhung loads can be tolerated, depending on such operating characteristics as speed, weight, and center of gravity of load. Care should be taken to make certain that the shaft is properly aligned. Couplings should be of proper size and flexibility to adequately protect bearings from undue stress and shock loading.

            [post_content] => When torque control/torque measurement must be performed at the highest possible power, Magtrol AHB Series Hysteresis Brakes are ideal. Passages running through the brakes enables compressed air cooling, providing excellent heat dissipation. This design allows for continuous power ratings up to 3000 watts (5300 watts intermittent). Use of pre-loaded bearings in the AHB Series Hysteresis Brakes allows operation at speeds of up to 25,000 rpm for extended durations. AHB Brakes are conveniently base mounted. Base mounting, with integral barrier type terminal strip, provides easy mounting and wiring.
