High Quality RN200 Cylindrical Roller Bearing

Short Description:

Cylindrical roller bearings are bearings with cylindrical rollers that can withstand radial and certain axial loads. Its inner and outer cylindrical surfaces are raceway surfaces, and the rollers roll on the raceway surface to withstand the load. Cylindrical roller bearings have simple structure and good durability. They are usually used in high-speed rotation and heavy load situations, such as wheel bearings or main bearing of industrial machinery equipment. Cylindrical roller bearings can be divided into multiple series based on different sizes, structures, and application scenarios. Common series include:

1. Single row cylindrical roller bearings: NU, NJ, NUP, N, NF and other series.

2. Double row cylindrical roller bearings: NN, NNU, NNF, NNCL and other series.

Product Application

Cylindrical roller bearings have the characteristics of high load-bearing capacity, high rotational speed, good stiffness, wear resistance, and long service life, and are widely used in mechanical equipment, especially in heavy load, high rotational speed, or high vibration and impact conditions. The following are the application ranges of cylindrical roller bearings:

1. Metallurgical machinery: rolling mills, cold rolling mills, hot rolling mills, casting machinery, etc.

2. Construction machinery: excavators, loaders, cranes, bulldozers, etc.

3. Electric machinery: hydro generators, wind turbines, steam turbines, transformers, etc.

4. Petroleum machinery: oil pump, oilfield drilling rig, oil rig, etc.

5. Railway machinery: high-speed trains, urban rail transit, subways, etc.

6. Automobile manufacturing: transmission, rear axle, steering gear, engine, etc.

7. Processing of bearing accessories: bearing covers, jackets, bearing seats, bearing liners, etc.

8. Others: food machinery, textile machinery, pipeline machinery, etc. It is necessary to choose the appropriate model, size, and quality level of cylindrical roller bearings based on the usage scenario and requirements.

About Cylindrical Roller Bearings

1.Cylindrical roller bearings are separable bearings, installation and removal is very convenient.

2.Cylindrical roller bearings can withstand greater radial load, suitable for use in high speed applications.

3.Cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings and other different structures.

4.Cylindrical roller bearings can be divided into PO, P6, P5, P4, P2 according to accuracy class.

Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.

Product Introduction

The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.

There are different types designated NU, NJ, NUP, N, NF for single-row bearings,and NNU, NN for double-row bearings depending on the design or absence of side ribs.
