NU 2203 Series China Manufacturer High Quality Low Noise High Load Brass Cage Single Row Cylindrical Roller Bearings

Series of single-row cylindrical roller bearings Popular types of Single row cylindrical roller bearings: - N - NJ - NU - NUP Bearings of N design are single row cylindrical roller bearings with two fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement within certain limits of the shaft about the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the N Series bearings have virtually no thrust capacity. They are single-row cylindrical roller bearings with two fixed ribs on the outer ring and a fixed rib on the inner circle, which can guide the shaft in a single direction (axially). Features of single row cylindrical roller bearings - Low friction (Roller end/flange contact area) The open flange design, roller end design, and surface finish promote lubricant film formation, resulting in lower friction and higher axial load carrying capacity. - Long service life The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection. - Enhanced operational reliability The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film. - Separable and interchangeable The separable components of cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections. - High-speed capability The cage designs suit high speeds, rapid accelerations, and peak loads.
