Product Description: Harbin Bearings - Cylindrical Roller Bearings are available in single-row and double-row configurations; these bearings feature linear contact between the 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 transportation machinery. A complete range of bearing models is available.

Here is the basic knowledge of cylindrical roller bearings from the Harbin Bearing Introduction

Harbin Bearings | Cylindrical Roller Bearings Categories:

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

1.1.1 Single-row cylindrical roller bearings: They are separable bearings, easy to install and dismantle. Both rings can be used with tight fits, and the corrected contact line between the rollers and raceways can reduce stress concentration.

1.1.2 The double-row cylindrical roller bearings are sliding bearings, which feature easy installation and disassembly due to their separability. Both rings can be used with a tight fit. The double-row cylindrical roller bearings almost do not allow any tilt angle.

1.2 Cylindrical roller bearings, categorized by whether the races have flanges, include single-row types such as NU, NJ, NUP, N, NF, and double-row types like NNU, NN. This bearing features a separable inner and outer race design.

Section 2: Harbin Bearings - Features of Cylindrical Roller Bearings

The cylindrical roller bearings feature linear contact between the rollers and raceways, offering high radial load capacity and suitability for bearing heavy and shock loads.

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

3. N and NU type cylindrical roller bearings are axially movable, capable of adapting to 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 precise machining of the shaft or housing bore. The installation of the bearing must control the relative skew of the outer ring axis to avoid concentrated contact stress.

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

Section 3: Harbin Bearing - 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 transportation machinery.

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

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