71902-LLB ABEC5 Enduro Angular Contact Bike Bearing 15x28x7

Angular Contact (A/C) cartridge bearings are 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, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely.

When fitting these angular contact bearings ensure the load is applied to the inner ring on the red seal side of the bearing.

Enduro ABEC-5 Specification:

Grade 5 Chromium Steel Balls
High precision balls are within 5/1,000,000″ round. R-64 hardness, of the highest grade.

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-5 precision and noiseless movement.

Graphite/Nylon Ball Retainers
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.

The ABEC-5 Standard
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.

Replaced my shot orbea wild non drive side bearing on DT Swiss 1900ís, i find this bearing placement takes quite a lot of abuse being an ebike and quite exposed compared to the sprocket/drive side, this bearing being a higher spec than oem, itís been great so far and will definitely be back for the front hub.
An excellent service from Wychbearings
