The KOYO 6040ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 200mm bore x 310mm outside diameter x 51mm width.
Load ratings: dynamic 272 kN (Cr) and static 243 kN (C0r) – fatigue load limit 11.3 kN. Limiting speed 1900 rpm with grease lubrication and 2300 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.
