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.
