The KOYO 6915ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 75mm bore x 105mm outside diameter x 16mm width.
Load ratings: dynamic 30.5 kN (Cr) and static 22.6 kN (C0r) – fatigue load limit 1.20 kN. Limiting speed 6100 rpm with grease lubrication and 7200 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.
