Koyo IR-1212 Inch Series Regular Width Inner Ring, 3/4 in ID x 1 in OD, 0.765 in OAW, For Use With B-1610, B-1612, BH-1610, BH-1612, J-1612, JH-1612, M-16101, M-16121, MH-16121, MJH-16121 Drawn Cup Needle Roller Bearing, Steel
Where it becomes impractical to meet the shaft raceway design requirements (hardness, case depth, surface finish, etc.) outlined in the engineering section, standard inner rings for drawn cup bearings are available. Inner rings for drawn cup bearings are designed to be a loose transition fit on the shaft and should be clamped against a shoulder. If a tight transition fit must be used to keep the inner ring from rotating relative to the shaft, the inner ring OD as mounted, must not exceed the raceway diameters required by the drawn cup bearing for the particular application.
