IR-M stainless steel inner ring

The IR-M series is a stainless steel inner ring specifically designed for needle roller bearings, suitable for use with needle roller bearings without inner rings. It is made of stainless steel material, with high-precision grinding of the raceway, perfectly compatible with needle rollers, and can be assembled and replaced separately. It is suitable for working conditions that require rust prevention and corrosion resistance. It is a special matching inner ring for needle roller bearings without inner rings and is widely used in various transmission systems that require radial support.
