The KOYO 6212ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 60mm bore x 110mm outside diameter x 22mm width.
Load ratings: dynamic 65.6 kN (Cr) and static 36.2 kN (C0r) – fatigue load limit 2.40 kN. Limiting speed 5700 rpm with grease lubrication and 6900 rpm with oil lubrication. Minimum fillet radius 1.5mm.
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.
