The KOYO 6905-2RS is a single-row deep groove ball bearing with double contact rubber seals (2RS) – measuring 25mm bore x 42mm outside diameter x 9mm width.
Load ratings: dynamic 8.75 kN (Cr) and static 4.55 kN (C0r) – fatigue load limit 0.230 kN. Limiting speed 9300 rpm with grease lubrication. Minimum fillet radius 0.3mm.
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.
