Single row cylindrical roller bearing are usually only subjected to radial force. Compared with ball bearings of the same size, the radial bearing capacity is increased by 1.5-3 times, with good rigidity and impact resistance. It is especially suitable for rigid supports and short shafts. Axial displacement of shafts caused by thermal elongation and installation and disassembly require machine accessories of separable bearings.

Structure

The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it 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. The bearing is a structure in which the inner ring and the outer ring can be separated.

Cylindrical roller bearing without ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction.
