Single-row Cylindrical Roller Bearings

QY948

Single-row cylindrical roller bearings typically carry only radial forces and have a separable structure with inner and outer rings. Cylindrical roller bearings with no ribs on either the inner or outer ring can move relatively in the axial direction, making them suitable for use as free-end bearings. Cylindrical roller bearings with double ribs on one side of the inner and outer rings and single ribs on the other side can carry a certain degree of axial load in one direction.

N type bearings features two integral flanges on the inner ring and outer ring without flanges.

NU type bearings features two integral flanges on the outer ring and inner ring without flanges, N and NU type bearings belong to the Non-locating bearings, they are not able to accommodate any axial loads.

NJ type bearings features two integral flanges on the outer ring and one integral flange on the inner ring, this allows them to accommodate axial loads in one direction only.

NUP type bearings have two integral flanges on the outer ring, one integral flange on the inner ting and a loose rib, so it is locating bearing and can accept axial loads in either direction.

NJ type bearings used in conjunction with thrust collars can build a locating bearing, which can accept axial loads in either direction.
