supply angular contact ball bearing 3304 3304 A/C3 size 20x52x22.2mm skateboard bearings
Bearing Description of Angular Contact Ball Bearing:
Angular contact ball bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient, Retainers are made of brass, synthetic resins or others subject to indive dual bearing features and application conditions.
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to
each other in the direction of the bearing axis. This means that
these bearings are designed to accommodate combined loads, i.e.
simultaneously acting radial and axial loads.
Angular contact ball bearings are available as:
single row angular contact ball bearings
double row angular contact ball bearings
four-point contact ball bearings
Super-precision angular contact ball bearings
Double row cam rollers
Hub bearing units
