Cylinder Roller Bearing

Cylindrical Roller Bearing (Cylindrical Roller Bearing) Cylindrical roller bearings are separable bearings, which are very convenient to install and disassemble. Cylindrical roller bearings can withstand large radial loads and are suitable for use in high-speed operation. Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation.

Cylindrical roller bearings are available in different designs, dimension series and sizes. Most of these are single row bearings with one cage. Together with single-row and double-row full-roller bearings (without cage), it constitutes a standard set of bearing varieties for general engineering. Bearings with cages can withstand heavy radial loads and operate at high speeds. Full complement bearings are suitable for very heavy radial loads at moderate speeds.

In cylindrical roller bearings, the rollers are the key components. Its geometry, the so-called logarithmic profile, provides optimal stress distribution in the bearing's contact area. Its surface finish maximizes the formation of a lubricant film and optimizes the rolling of the rollers. The resulting benefits include increased operational reliability and greater tolerance for misalignment compared to conventional designs.

The range of cylindrical roller bearings includes the following basic types:

  • Single row cylindrical roller bearings with cages, mainly NU, NJ, NUP and N Design
  • Double Row Cylindrical Roller Bearing with Cage, Mainly Designed for NNU and NN
  • Multi Row Cylindrical Roller Bearing with Cage
  • Single Row Full complement cylindrical roller bearings, mainly for NCF and NJG designs
  • Double row full complement cylindrical roller bearings mainly for NNF designs
  • Multiple row full complement cylindrical roller bearings , with four or eight rows of rollers
  • In addition to the standard varieties, cylindrical roller bearings also include:
  • Single-row high-precision all-steel or ceramic cylindrical roller bearings;
  • Double row high precision all steel or ceramic cylindrical roller bearings;
  • cylindrical roller bearings and bearing assemblies for railway axle boxes;
  • traction motors for railway applications
  • Open or sealed multi-row cylindrical roller bearings for rolling mills;
  • Support bearings for multi-roll cold rolling mills;
  • Indexing roller assemblies for continuous smelting furnaces.
