The KOYO 6240-1ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 200mm bore x 360mm outside diameter x 58mm width.
Load ratings: dynamic 314 kN (Cr) and static 293 kN (C0r) – fatigue load limit 13.1 kN. Limiting speed 1600 rpm with grease lubrication and 1900 rpm with oil lubrication. Minimum fillet radius 4mm.
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.
