The MR imperial series is a non inner ring imperial needle roller bearing (outer ring+needle roller+cage component), with the raceway formed by the journal or MI imperial inner ring, suitable for radial support of imperial equipment, with high load-bearing capacity, compact radial shape, and adaptability to medium and low-speed heavy loads. It is commonly used in engineering machinery, automotive transmission, agricultural machinery and other fields.
