The KOYO 6011ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 55mm bore x 90mm outside diameter x 18mm width.
Load ratings: dynamic 35.3 kN (Cr) and static 21.2 kN (C0r) – fatigue load limit 1.25 kN. Limiting speed 7600 rpm with grease lubrication and 8900 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.
