The NKE NA4836 is a genuine Needle Roller Bearing without an inner ring, manufactured by NKE. This design is ideal for applications where the shaft itself can be hardened and ground to serve as a raceway, allowing for a compact bearing arrangement. It features a bore diameter of 180 mm, an outer diameter of 220 mm, and a width of 60 mm. Engineered for robust performance, it boasts a basic dynamic load rating (Cr) of 228 kN and a basic static load rating (C0r) of 350 kN, ensuring high radial load capacity. The bearing has a limiting speed of 1700 1/min and a reference speed of 2200 1/min, weighing 4.8 kg. It is suitable for demanding industrial applications requiring reliable and efficient operation.
