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

Seals or Shields = LLU = Full contact, dual lip seal riding in a groove on the inner race. With more sealing pressure, these are ideal for pivots or headsets that continually come in contact with dirt, sweat, and dust. The increased seal pressure and 2 lips help retain the 90% grease fill we use on these bearings to better displace any moisture and continually lubricate the balls and races.
