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

UPC = 810191011590
Precision Grade = ABEC 3
Inside Diameter = 12.700mm = 1/2"
Outside Diameter = 19.050mm = 3/4"
Width = 3.969mm = 5/32"
Seals or Shields = Rubber Seals = These bearings have the suffix 2RS indicating they have lip seals on both sides and are pre-filled with grease for life, so no lubrication is required. The seals give some protection against ingress of moisture and contaminating particles entering the raceways, thus increasing the life of the bearing. Some applications require only 1 seal which can easily be removed
