The KOYO 6221ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 105mm bore x 190mm outside diameter x 36mm width.
Load ratings: dynamic 166 kN (Cr) and static 105 kN (C0r) – fatigue load limit 5.70 kN. Limiting speed 3300 rpm with grease lubrication and 3900 rpm with oil lubrication. Minimum fillet radius 2.1mm.
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.
