Note 1) Dimensional tolerance to secure ordinary clearance when any of these inner rings is combined with needle roller bearing with no inner ring.
2) Allowable minimum chamfer dimension r .
Remarks: 1. Nominal number plus code "D" represents inner ring with oil hole.
2. Nominal number plus ˞-mark represents inner ring with fine-chamfered outer surface.
