Cylindrical roller bearings, rolling element is a cylindrical roller bearing to the heart. Cylindrical roller and raceway for the line contact bearings.Load capacity,the main radial load.
The rolling element and ring wall friction is small, suitable for high-speed rotation.
The roller of the cylindrical roller bearing is in line contact with the raceway, so the bearing can bear heavier radial load.
Accodring to ring without gear side,can be divided NU,NJ,NUP,N,NF single row bearings, and NNU.NN double row bearings.
