IKO NAG 4901,NAU 4901 Nots
Notes(1) Minimum allowable value of chamfer dimension r
(2) Allowable rotational speed applies to oil lubrication. For grease lubrication, a maximum of 60% of this value is allowable.
Considering that the axial load acts under practical operating conditions, up to 1/10 of this value is recommended for actual use.
Remarks1. The NAG and NAU series with a bore diameter d of 17 mm or less have no oil hole. In others, the outer ring has an oil groove and
two oil holes.
2. No grease is prepacked. Perform proper lubrication.
