The KOYO 6328ZZX is a single-row deep groove ball bearing with double metal shields (ZZX) – measuring 140mm bore x 300mm outside diameter x 62mm width.
Load ratings: dynamic 316 kN (Cr) and static 246 kN (C0r) – fatigue load limit 15.6 kN. Limiting speed 2100 rpm with grease lubrication and 2500 rpm with oil lubrication. Minimum fillet radius 4mm.
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.
