71902 (6902) ABEC 5 AC Bearing
C$15.00
- Description
- Grade 5 steel balls with ABEC 5 precision
- Made with a 15 degree contact angle
- NOTE: These bearings are directional. Always install with the ORANGE/RED seal facing out, and "load" the inner race!
- These Angular Contact bearings are specifically designed for hubs that have a preload feature (and certain bottom bracket applications).
In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. But in these A/C bearings, ALL balls are engaged and spread the force over a larger surface area, which decreases friction, and minimizes wear.
