The 6900 Series Thin-Section Deep Groove Ball Bearings provide smooth rotation in compact equipment with limited radial installation space. Their thin cross-section and relatively small outside diameter help reduce the size and weight of mechanical assemblies.
Compared with the 6800 series of the same bore size, the 6900 series normally has a larger cross-section and higher load capacity. Common models include 6900, 6901, 6902, 6903, 6904 and 6905. Open, ZZ metal-shielded and 2RS rubber-sealed versions are available.
Product Features
Thin-section design: The compact cross-section saves radial installation space.
Deep groove raceway: The bearing supports radial loads and limited axial loads in both directions.
Smooth rotation: Precision balls and raceways help reduce friction and vibration.
Multiple sealing options: Open, ZZ and 2RS versions suit different operating environments.
Wide model range: Different bore diameters and widths match various shafts and housings.
Roller integration: The bearing can be assembled with plastic, rubber or metal outer wheels.
OEM support: Grease, clearance, seal type and roller dimensions can be customised.
