71903 LLB Enduro Bike Angular Contact Bearing

Precision Tolerance: ABEC5

Seals: LLB

Material: 52100 High Carbon Chromium Alloy Races

Enduro produce a line of Angular Contact (A/C) cartridge bearings specifically designed for hubs. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear. Wheel play can be adjusted out of the hub providing a more stable wheel, and making it easier to adjust disc brakes while still spinning freely.

LLB is a double-lip type seal making light contact and also rides in a groove making a labyrinth seal.
