The KOYO 6906ZZ is a single-row deep groove ball bearing with double metal shields (ZZ) – measuring 30mm bore x 47mm outside diameter x 9mm width.
Load ratings: dynamic 9.05 kN (Cr) and static 5.00 kN (C0r) – fatigue load limit 0.260 kN. Limiting speed 14000 rpm with grease lubrication and 17000 rpm with oil lubrication. Minimum fillet radius 0.3mm.
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.
