RNA4907 Bearing 42x55x20mm

RNA4907 Bearings with radial structure is compact, its inner diameter size and load capacity and other types of bearings at the same time, the minimum outside diameter, particularly applicable to the limited size of radial installation supporting results. This kind of bearing inner ring, applicable to the limited size of radial installation supporting structure, to suit the bearing of the shaft neck directly as a rolling surface. At the same time, because without the inner ring, and the diameter of the shaft can be appropriately increased, thereby increases the rigidity.
