Cylindrical Roller Bearing
- Sep 18, 2018 -

Cylindrical roller bearing is a linear roller bearing with a cylindrical roller and raceway. Load capacity, mainly bear radial load. The rolling element has little friction with the ferrule rib and is suitable for high speed rotation.

Cylindrical rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The rolling element has little friction with the ferrule rib and is suitable for high speed rotation. According to the ferrule with or without ribs, 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 are separable.


Cylindrical roller bearings with no 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. A cylindrical roller bearing with a single rib on one side of the inner and outer rings and a single rib on the other side can withstand a certain degree of axial load in one direction. Steel stamping cages or copper alloy solid cages are commonly used. However, some use polyamide shaped cages.


The roller of the cylindrical roller bearing is in line contact with the raceway and has a large radial load capacity. It is suitable for bearing heavy loads and impact loads, and is also suitable for high-speed rotation. At the same time, it improves the lubrication conditions of the contact area between the roller end face and the rib, and improves the performance of the bearing. Generally applicable to large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery. At present, the current market situation of cylindrical roller bearings is:


First, small, good quality, high price, small purchase

Manufacturers should vigorously improve production levels, optimize product quality, reduce production costs, and attract and promote market consumer demand.


Second, the development space is large, and the market demand needs to be improved.

The current cylindrical roller bearing market environment is still very occluded, cylindrical roller bearings are mainly used in industrial production. In the dealer's warehouse, everywhere, the full range. Therefore, it is necessary to expand the market, increase market demand, and promote development.
