The KOYO 6820ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 100mm bore x 125mm outside diameter x 13mm width.
Load ratings: dynamic 24.5 kN (Cr) and static 21.2 kN (C0r) – fatigue load limit 1.05 kN. Limiting speed 4800 rpm with grease lubrication and 5700 rpm with oil lubrication. Minimum fillet radius 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.
