The KOYO 6234ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 170mm bore x 310mm outside diameter x 52mm width.
Load ratings: dynamic 265 kN (Cr) and static 223 kN (C0r) – fatigue load limit 11.1 kN. Limiting speed 1900 rpm with grease lubrication and 2300 rpm with oil lubrication. Minimum fillet radius 4mm.
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.
