Single row cylindrical roller bearings belong to the group of radial roller bearings. They are primarily used for very stiff bearings with high loads. With these bearings it is important to note the respective design variants:

• Type N has two fixed flanges on the inner ring and one flangeless outer ring. This type allows for axial displacement between shaft and housing in both directions.
• Type NU has two fixed flanges on the outer ring; the inner ring is flangeless. This variant also allows for axial displacement in both directions.
• Type NJ has two fixed flanges on the outer ring and one fixed flange on the inner ring. This variant only allows for axial displacement between shaft and housing in one direction.
• Type NUP has two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange ring. Type NUP is used as a fixed bearing and does not allow for any axial displacement between shaft and housing.
