Versatility and flexibility are the real benefits found in MAGPOWR’s Global Series Magnetic Particle Brakes, as they provide smooth, repeatable, controllable torque independent of speed. This makes them suitable for all kinds of power transmission and tensioning applications. Sizes are available from 5.5 to 325 lb-ft of torque.

This line of brakes features state-of-the-art magnetic particle technology and its compact size is due to through-bores on all machined housings for ease of mounting. The M (Metric) series boasts full metric bores and keyways, as well as metric mounting hardware and setscrews to support international design requirements. The brakes are also available as 24 vdc or 90 vdc.

Models available by Rated Torque:
GBA: 7.5 Nm (5.5 lb-ft)
GBB: 14 Nm (11 lb-ft)
GBC: 35 Nm (26 lb-ft)
GBD: 75 Nm (56 lb-ft)
GBE: 135 Nm (100 lb-ft)
