The KOYO 6309ZZC3 is a single-row deep groove ball bearing with double metal shields (ZZ) – 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 6800 rpm with grease lubrication and 8100 rpm with oil 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 metal shields retain the factory-filled grease and keep out dust and debris while allowing higher speeds than a contact seal.
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.
