Low-friction, high-speed bearing solutions for electric motors, pumps, gearboxes, agricultural machinery and general industrial equipment.
2RS + SNAP RING GROOVEDeep groove ball bearings are widely used because of their simple construction, low friction and suitability for high rotational speeds. They primarily support radial loads and can also accommodate axial loads in both directions.
AOSN supplies open, rubber-sealed, steel-shielded and snap-ring-groove configurations. Clearance, cage, grease and precision grade can be confirmed to match the application.
Five practical configurations using your supplied AOSN product photography. Send the complete designation when requesting a quotation.
Two contact rubber seals help retain grease and exclude contamination; the outer-ring groove accepts a locating snap ring.

Open, ZZ steel shield or 2RS rubber seal configurations.
Plain outer ring or snap-ring groove with optional locating ring.
Standard deep groove geometry or BL maximum-capacity filling-slot design.
Clearance, grease, cage, noise level and precision grade by confirmation.
The existing AOSN BL data is retained unchanged. Published load ratings and limiting speeds continue to use the previously approved 40% reduction.
