The KOYO 6218ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 90mm bore x 160mm outside diameter x 30mm width.
Load ratings: dynamic 120 kN (Cr) and static 71.5 kN (C0r) – fatigue load limit 4.20 kN. Limiting speed 3900 rpm with grease lubrication and 4700 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.
