Cylindrical Roller Bearings
Most of our cylindrical roller bearings are separable. This 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 can allow a small angular error between inner axes and outer axes in the range of 2-4. Therefore, it requires higher machining 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, our 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.
Type N
Bearings of type N have two integral flanges on inner ring and a flange-less outer ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft.
