The KOYO 6930ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 150mm bore x 210mm outside diameter x 28mm width.
Load ratings: dynamic 117 kN (Cr) and static 94.3 kN (C0r) – fatigue load limit 3.75 kN. Limiting speed 2900 rpm with grease lubrication and 3400 rpm with oil lubrication. Minimum fillet radius 2mm.
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.
