IKO RNAF 223013,RNAFW 223026 Nots
Notes(1) Minimum allowable value of chamfer dimension r
(2) Allowable rotational speed applies to oil lubrication. For grease lubrication, a maximum of 50% of this value is allowable.
Remarks1. The character “N” at the end of the identification number indicates that a synthetic resin cage is incorporated.
2. RNAF has no oil hole. RNAFW is provided with an oil groove and an oil hole on the outer ring.
3. No grease is prepacked. Perform proper lubrication.
