Product Description: Harbin Bearings - Cylindrical Roller Bearings are available in single-row and double-row configurations. The cylindrical roller bearings feature linear contact between rollers and raceways, offering high radial load capacity and suitability for heavy and shock loads. The inner or outer rings can be separated for easy installation and removal. Due to their inherent characteristics, cylindrical roller bearings are widely used in large and medium-sized electric motors, locomotive vehicles, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, and lifting and conveying machinery. A complete range of bearing models is available.

Here is the basic knowledge of cylindrical roller bearings from Harbin Bearings introduction

Harbin Bearings | Cylindrical Roller Bearings Classification:

1.1 Cylindrical roller bearings are categorized based on the number of rolling elements: single-row cylindrical roller bearings and double-row cylindrical roller bearings.

1.1.1 Single-row cylindrical roller bearing: It is a separable bearing, easy to install and dismantle, both rings can be used with tight fit, and the corrected contact line between the roller and raceway can reduce stress concentration.

1.1.2 Double-row cylindrical roller bearings are sliding bearings, with their separability making installation and removal very convenient. Both rings can be used with a tight fit. Double-row cylindrical roller bearings almost do not allow any inclination angle.

1.2 Cylindrical roller bearings, classified by whether they have ribs on the rings, include single-row types such as NU, NJ, NUP, N, NF, as well as double-row types like NNU and NN. This bearing features a separable inner and outer ring structure.

Section 2: Harbin Bearings - Features of Cylindrical Roller Bearings

Cylindrical roller bearings have rolling elements in line contact with the raceways, offering high radial load capacity and are suitable for bearing heavy and impact loads.

2. Cylindrical roller bearings have a low friction coefficient, suitable for high speeds, with their maximum speed nearly approaching that of deep groove ball bearings.

3. N and NU type cylindrical roller bearings are axially movable, capable of accommodating changes in the relative position of the shaft and housing due to thermal expansion or installation errors, and can be used as a free-end support.

4. Cylindrical roller bearings require high precision machining of the shaft or housing bore. Strict control over the relative skew of the outer race axis after installation is essential to avoid contact stress concentration.

5. The inner or outer ring of the cylindrical roller bearing is separable for easy installation and removal.

Section 3: Harbin Bearings - Cylindrical Roller Bearings Applications

Cylindrical roller bearings, due to their inherent characteristics, are widely used in large and medium-sized electric motors, locomotive vehicles, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, and lifting and conveying machinery.

IV. The Impact of Temperature on the Life of Cylindrical Roller Bearings

When the operating temperature of cylindrical roller bearings exceeds 120℃, the bearing components will lose their original dimensional stability. Therefore, for bearings operating at temperatures above 120℃, special requirements can be made to HRB Company for the selection of bearings that have undergone special heat treatment.
