China Double Cylindrical Roller Bearing Factory – Cylindrical Roller Bearings NJ 2300 series – Nice Bearing

Product Description

Cylindrical Roller Bearingsare bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings.As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Design And Features

Design for high radial loads and shock loads while maintaining high-speed rotation characteristics. Components  are separable and interchangeable, which is convenient for installation, disassembly and inspection. The followings are several common designs of cylindrical roller bearings.The difference  is reflected in the flange design of the inner ring and the outer ring, as well as the structure and material of the cage. NU Design Bearings have a outer ring with two integral flanges and an inner ring with no flanges,so they can accommodate axial displacement of the shaft relative to the housing in both directions . Axial fixation can be achieved with the angle ring. N Design Bearings have an inner ring with two integral flanges and a outer ring without flanges,so they can accommodate axial displacement of the shaft relative to the housing in both directions. NJ Design Bearings  have a outer ring with two flanges and an inner ring with one flange, so they are used to axially locate the shaft in one direction. Axial fixation in the other direction can be achieved with an angle ring. NUP Design Bearingshave two integral flanges on the outer ring and one integral flange and a loose flange ring on the inner ring so they are used to locate the shaft axially in both directions.
