For grease lubrication, a maximum of 60% of this value is allowable.Remarks1. AF series with a roller set bore diameter Fw of 26 mm or less have no oil hole. In others, the outer ring has an oil groove and an oil hole.2. o grease is prepacked. Perform proper lubrication.D7MACHINED TYPE NEEDLE ROLLER BEARINGSWithout Inner Ring
