Description

Most of LYC cylindrical roller bearings are separable which make it very convenient to mount and dismount. Cylindrical roller bearings can carry heavier radial load and are suitable to be used in the condition of high speed.

This type of bearings only can allow a small angular error between inner axes and outer axes in the range of 2 ~ 4. Therefore it requires higher machined precision on shaft and housing; otherwise asymmetrical load and stress would be focused at the position of raceway. However this situation can be improved by correcting the contacted generatrix of rollers or raceways.

According to different rows LYC cylindrical roller bearings are divided into single row double-row and multi-row cylindrical rollers. These differences are also displayed on the design of flange position. The common used types of LYC cylindrical roller bearings are as following.

Type N NU

Bearings of type N have two integral flanges on inner ring and a flangeless outer ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft.

The bearings of type NU have two integral flanges on outer ring and a flangeless inner ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft.

Therefore this type of bearings is suitable to be used as non-locating bearings.

Type NJ NF

Bearings of type NJ have two integral flanges on outer ring and one on inner ring. This type of bearings can carry a certain amount of axial loads in single direction.

Bearings of type NF have one flange on outer ring and two integral flanges on inner ring. This type of bearings can carry a certain amount of axial loads in single direction.

Therefore they are suitable to be used as an axial location bearing in single direction.
