The KOYO 6702ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 15mm bore x 21mm outside diameter x 4mm width.
Load ratings: dynamic 1.15 kN (Cr) and static 0.580 kN (C0r) – fatigue load limit 0.024 kN. Limiting speed 29000 rpm with grease lubrication and 35000 rpm with oil lubrication. Minimum fillet radius 0.2mm.
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.
