Cylindrical Roller Bearing Description
The cylindrical roller and raceway are line contact bearings. They
have large load capacity and mainly bear radial loads. The friction
between the rolling element and the rib of the ferrule is small,
which is suitable for high-speed rotation. According to whether the
ferrule has ribs or not, they can be divided into single-row
cylindrical roller bearings such as NU, NJ, NUP, N, NF, and
double-row cylindrical roller bearings such as NNU and NN. Cylindrical Roller Bearing Product number
