Single-row deep groove ball bearing - Shielded (ZZX)

The KOYO 6317ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 85mm bore x 180mm outside diameter x 41mm width.

Load ratings: dynamic 166 kN (Cr) and static 96.8 kN (C0r) – fatigue load limit 6.35 kN. Limiting speed 3700 rpm with grease lubrication and 4400 rpm with oil lubrication. Minimum fillet radius 3mm.

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.
