 Specifications of  RAN4902 bearing roller nylon

             RNA4902 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.

RAN4902 bearing roller nylon Descriptions

 Needle bearings have a large surface area that is in contact with the bearing outer surfaces. Additionally there is less added clearance so they are much more compact. The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race and sometimes housing itself. Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles. Full compliment bearings have solid inner and outer rings and rib-guided cylindrical rollers.
