The KOYO 63/32ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 32mm bore x 75mm outside diameter x 20mm width.
Load ratings: dynamic 37.6 kN (Cr) and static 16.2 kN (C0r) – fatigue load limit 1.30 kN. Limiting speed 9300 rpm with grease lubrication and 11000 rpm with oil lubrication. Minimum fillet radius 1.1mm.
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.
