BHM / BMM Series BEARHUG Locknuts – Hardened Alloy

BHM (inch) and BMM (metric) are the high-strength BEARHUG locknuts, machined from hardened alloy instead of carbon steel so the nut can carry substantially higher clamp load and axial thrust without spanner slots deforming. The prevailing-torque polymer locking ring is unchanged, so the nut still self-locks and still re-sets.

BHM / BMM Series Specifications

  • Part numbers: BHM-00 through BHM-30; BMM-00 through BMM-30 (58 sizes stocked)
  • Bore / shaft size (inch): 0.391 in to 5.888 in
  • Outside diameter (inch): 0.75 in to 7.688 in
  • Bore / shaft size (metric): 10 mm to 150 mm
  • Outside diameter (metric): 18 mm to 195 mm
  • Material & temperature: Hardened alloy steel with a heat-stabilized polymer locking ring; 160°F maximum operating temperature
  • Standards: BHM to ANSI/ABMA 8.2-1999, BMM to ISO 2982-2:2013(E); made in USA, RoHS

Applications

Heavily preloaded spindles, rolling mill and press assemblies, large gearboxes and any bearing seat where the clamp load would yield a carbon steel nut.
