Cylindrical roller bearings, rolling element is a cylindrical roller to the heart of rolling bearings. Cylindrical roller and raceway for the line contact bearings. Load capacity, mainly to bear radial load. Rolling body and ferrule wall friction is small, suitable for high-speed rotation. According to whether the ring ring, can be divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN and other double row bearings.

Roller and raceway for line contact or repair off-line contact, radial bearing capacity, suitable for heavy load and impact load.

Friction coefficient is small, suitable for high-speed, speed close to the deep groove ball bearings.

N-type and NU-type axial movement, can adapt to thermal expansion or installation error caused by the relative position of the shaft and the shell changes, can be used for free-end support.

The shaft or seat hole processing requirements are higher, the relative deviation of the outer ring axis after installation to strict control, so as not to cause contact stress concentration.

The inner or outer ring is separable for easy installation and removal.
