NJSKT Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements.This kind bearing are generally only used to bear radial load, compared with the same size deep groove ball bearings, have a greater radial load capacity, speed close to the deep groove ball bearings, but with such a bearing with the shaft higher processing requirements shell holes, allowing the inner ring and outer ring axis tilt axis is small as beyond the limits of the two axis tilted roller in contact with the ring raceway situation will deteriorate severely impact of load bearing capacity, reduce bearing life. Therefore, these bearings need to be installed, such as the role of the host axial load component, only the simultaneous use of other types of bearings to withstand axial load premise before use.

Features of cylindrical roller Bearing

1.High load carrying capacity 
Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads.
2.Low friction (Roller end / flange contact area) 
The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
3.Long service life 
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
4.Enhanced operational reliability 
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
5.Separable and interchangeable 
The separable components of double row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
6.High speed capability 
The cage designs are suitable for high speeds, rapid accelerations and peak loads.
