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

The KOYO 6324ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 120mm bore x 260mm outside diameter x 55mm width.

Load ratings: dynamic 258 kN (Cr) and static 185 kN (C0r) – fatigue load limit 12.6 kN. Limiting speed 2500 rpm with grease lubrication and 3000 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.
