MI Imperial Inner Circle

The MI series is a specialized imperial standard inner ring for needle roller bearings, without rollers/retainers, only designed for high-precision grinding of raceway inner rings. It is compatible with imperial standard needle roller bearings without inner rings (such as the MR series) to compensate for the insufficient hardness/accuracy of the shaft neck. It can be used by pressing on the shaft neck and is suitable for radial support scenarios of imperial standard equipment.
