Enduro Bearings are quality bearings manufactured specifically for cycling - certain applications require specific materials, greases, and sealing arrangements. Enduro has it covered for environments and disciplines.

  • LLB - Is a double lip seal making light contact, and also rides in a groove making a labrinth seal (reducing friction for less rolling resistance whilst maintaining a good seal, preventing contaminating particles entering the raceways)
  • 2RS - preventing contaminating particles entering the raceways)
Grade 10 Chromium Steel Balls:

High precision balls are within 10/1,000,000″ round, twice as round as the industry standard, at it’s highest level.

52100 High Carbon Chromium Alloy Races:

Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement.

Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance

Always install bearings by pressing on the outer race only into a housing
