An Angular Cylindrical Roller Bearing

An angular cylindrical roller bearing is a type of rolling-element bearing that can accommodate both radial and axial loads. This type of bearing has two rows of rollers that are arranged in a radial direction and axial direction. In addition to its radial load capacity, the double-row version is capable of accepting axial and radial loads that are parallel to the bearing's central axis.

NNU type bearings

Cylindrical roller bearings have two rows of rollers and are used for bearing spindle support in machine tools. They have a cylindrical inner ring and a conical outer ring and can be easily installed. Cylindrical roller bearings can withstand high radial loads and can be used for high-speed applications.

Cylindrical roller bearings of the NNU series are super-precision and have a double-row design. They are able to withstand heavy radial loads and high speeds while still maintaining high stiffness. They feature three flanges on the outer ring and no flanges on the inner ring. In addition to having a higher capacity, these bearings also have a lower friction coefficient and can accommodate radial displacement in both directions.

NNU type angular cylindrical roller bearing has a free-side use and is also suitable for fixed-end applications. This type of bearing has an inner ring that is loose, allowing it to adapt to changes in relative position of the shaft. The outer ring should be positioned on the outside of the bearing for ease of mounting.
