The KOYO 6924ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 120mm bore x 165mm outside diameter x 22mm width.
Load ratings: dynamic 71.6 kN (Cr) and static 56.9 kN (C0r) – fatigue load limit 2.50 kN. Limiting speed 3800 rpm with grease lubrication and 4400 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.
