The KOYO 6228-2RS is a single-row deep groove ball bearing with double contact rubber seals (2RS) – measuring 140mm bore x 250mm outside diameter x 42mm width.
Load ratings: dynamic 208 kN (Cr) and static 150 kN (C0r) – fatigue load limit 8.65 kN. Limiting speed 1600 rpm with grease lubrication. Minimum fillet radius 3mm.
Deep groove ball bearings are the most widely used bearing type – carrying radial and axial loads in both directions with low friction and high running accuracy. The double contact rubber seals give superior protection against dust – dirt and moisture for contaminated environments – and retain the factory-filled grease for life.
Manufactured by KOYO (JTEKT) in chrome steel to ISO standards.
