Industrial 1-055-531-00-FF Heavy Duty Industrial Brake

Stearns Industrial 1-055-531-00-FF is a heavy‑duty spring‑set disc brake from Stearns’ 55500/55000 family, built for rugged industrial equipment and available for AC or DC operation. In Stearns’ 55500‑series parts lists, the 9–10 lb‑ft torque range is represented by model numbers 1-055-530-00 (9 lb‑ft) and 1-055-531-00 (10 lb‑ft), with the 1-055-531-00 entry appearing in both standard configurations and vertical mounting references within the same family, and the -FF suffix indicating a variant of this brake. The standard assembly comprises an aluminum housing (8-007-533-00), endplates, a hub and set‑screw assembly, a stationary disc kit (5-66-8351-00), and a friction disc kit (5-66-8452-00), supported by stabilizing springs and the related hardware needed for installation. For adaptable installations, the same torque range is described with vertical mounting references (and related hardware kits) in the catalog, enabling alternatives to fit tight or unusual machine layouts. This brake is intended for industrial applications requiring reliable braking force and predictable release, such as machine tools and other heavy machinery where precise stop and hold functions are essential, with Stearns’ replacement parts and kits available to support ongoing maintenance and service of the unit.
