Cylindrical Roller Bearing
Cylindrical roller bearings use cylinders as rolling elements, unlike balls in ball bearings. In bearings of this type, the cylindrical roller bearings are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds. Different styles are designated NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).
Features of Cylindrical roller bearings
The rolling body is a centripetal rolling bearing of a cylindrical roller. The internal structure of cylindrical roller bearings adopts rollers arranged in parallel, and a spacer or isolation block is installed between the rollers, which can prevent the tilt of the rollers or the friction between the rollers and effectively prevent the increase of rotation torque.
Classification of Cylindrical roller bearings
The Cylindrical Roller Bearing is a separable bearing that is easy to assemble and disassemble. According to the row number of rollers, the cylindrical roller bearings can be classified into single-row, double-row, four-row, and full-complement cylindrical roller bearings.
