IKO NAS 5020UUNR,NAS 5020ZZNR Nots
Notes(1) Minimum allowable value of chamfer dimension r
(2) Allowable rotational speed applies to grease lubrication. Considering that the axial load acts under practical operating conditions,
up to 1/10 of this value is recommended for actual use.
Remarks1. The inner ring has an oil groove and two oil holes.
2. Roller Bearings for Sheaves are provided with prepacked grease.
