The KOYO 6209ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 45mm bore x 85mm outside diameter x 19mm width.
Load ratings: dynamic 40.9 kN (Cr) and static 20.3 kN (C0r) – fatigue load limit 1.40 kN. Limiting speed 7700 rpm with grease lubrication and 9200 rpm with oil 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 metal shields retain the factory-filled grease and keep out dust and debris while allowing higher speeds than a contact seal.
Manufactured by KOYO (JTEKT) in chrome steel to ISO standards.
