The KOYO 6309-2RSC3 is a single-row deep groove ball bearing with double contact rubber seals (2RS) – measuring 45mm bore x 100mm outside diameter x 25mm width.

Load ratings: dynamic 61.1 kN (Cr) and static 29.5 kN (C0r) – fatigue load limit 2.25 kN. Limiting speed 4500 rpm with grease lubrication. Minimum fillet radius 1.5mm.

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.

C3 internal clearance: this bearing is supplied with greater than normal (CN) internal radial clearance. C3 suits applications with an interference fit on the shaft or in the housing – a temperature differential between the inner and outer rings – or shaft expansion under load – where the extra clearance prevents the bearing from becoming preloaded in service.

Manufactured by KOYO (JTEKT) in chrome steel to ISO standards.
