The KOYO 6318ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 90mm bore x 190mm outside diameter x 43mm width.
Load ratings: dynamic 178 kN (Cr) and static 107 kN (C0r) – fatigue load limit 8.80 kN. Limiting speed 3500 rpm with grease lubrication and 4200 rpm with oil lubrication. Minimum fillet radius 3mm.
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.
