Single-row deep groove ball bearing - Contact Sealed (2RS)

The KOYO 6305-2RS is a single-row deep groove ball bearing with double contact rubber seals (2RS) – measuring 25mm bore x 62mm outside diameter x 17mm width.

Load ratings: dynamic 25.7 kN (Cr) and static 11.3 kN (C0r) – fatigue load limit 0.860 kN. Limiting speed 7500 rpm with grease lubrication. Minimum fillet radius 1.1mm.

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.
