Product Description

Product Description

       

        Cylindrical rollers and raceways are linear contact bearings. High load capacity, mainly bearing radial loads. The friction between the rolling element and the sleeve edge is small, suitable for high-speed rotation. According to the presence or absence of retaining edges in the ring, there are single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, as well as double row cylindrical roller bearings such as NNU and NN. This bearing is a separable structure with inner and outer rings.
        Cylindrical roller bearings with inner or outer rings without retaining edges, whose inner and outer rings can move relative to each other in the axial direction, can be used as free end bearings. A cylindrical roller bearing with double flanges on one side of the inner and outer rings and a single flange on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, steel plate stamping retaining frames or copper alloy solid retaining frames are used. But there are also some that use polyamide formed retaining frames.

Company Website: 
 

           Single row cylindrical roller bearings, as free supporting, are usually matched with angular contact ball bearings which serve as fixed supporting. The most commonly used cylindrical roller bearings in the machine tool are double cylindrical roller bearing with tapered bore.  This kind of bearing can bear greater radial load with detachable inner and outer rings, and can not bear the axial load , so they are often used with double-direction angular contact thrust ball bearings which bear axial load.

N type:

The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.

NU type:

The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

NJ type:

The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.

NF type:

The outer ring has one integral flange and the inner ring two integral flanges.

NUP type:

The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.

RN type:

No outer ring and the inner ring two integral flanges.

NN type:

NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. It can make shaft relative bearing between the axial displacement generated in both directions.
