What is Cylindrical roller bearing

Cylindrical roller bearings have high load capacity and mainly bear radial loads.The rolling element has low friction with the ring rib, which is suitable for high-speed rotation.According to the presence of ring 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.This bearing has a separable structure of inner and outer rings.

Cylindrical roller bearings with inner and outer rings without ribs can be used as free-end bearings because the inner and outer rings can move relative to the shaft in the axial direction.Cylindrical roller bearings with double ribs on one side of the inner and outer rings and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction.Generally, steel sheet stamping cages or copper alloy machined solid cages are used.However, some use polyamide molded cages.

Cylindrical rollers are in linear contact with the raceway, with high radial load capacity.They are suitable for both heavy and shock loads as well as high-speed rotation.

The raceway and rolling elements of cylindrical roller bearings are geometrical in shape.After improved design, they have high load-bearing capacity. The new structural design of the ribs and roller end faces not only improves the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end faces and the ribs, thereby enhancing the performance of the bearing.

Characteristics of cylindrical roller bearings

Strong load-bearing capacity: The rolling elements of cylindrical roller bearings are cylindrical, which can form a larger rolling contact area between the inner and outer rings of the bearing, thereby improving the load-bearing capacity of the bearing.This type of bearing is suitable for machinery and equipment that bear heavy and impact loads.

2. High operating stability: The design of cylindrical roller bearings enables the rolling elements to experience less rolling friction resistance between the inner and outer rings, thereby improving the operating stability of the bearing.This type of bearing is suitable for high-precision and high-speed rotational motion.

3. Convenient maintenance: The design of cylindrical roller bearings is simple, making maintenance relatively easy.If the bearing needs to be replaced or repaired, it can be easily disassembled and installed.

4. Wide range of applications: Cylindrical roller bearings can be used in a variety of different machines and equipment, such as machine tools, electric motors, pumps, and compressors.This type of bearing can be customized according to different needs to meet the requirements of different machines and equipment.

5. Low cost: The production cost of cylindrical roller bearings is relatively low, so the price is also relatively affordable.For some industries that require a large amount of bearings, choosing cylindrical roller bearings can reduce production costs.

In summary, cylindrical roller bearings have the characteristics of high load capacity, high operating stability, convenient maintenance, wide application range, and low cost.These characteristics make cylindrical roller bearings an excellent type of bearing, which is widely used in various fields and industries.

Application areas of cylindrical roller bearings

1. Transmission system

Cylindrical roller bearings are widely used in transmission systems, such as reducers, motors, and gearboxes.In these applications, cylindrical roller bearings can act as supporting and torque-transmitting components, with their low friction coefficient and high limit speed making the transmission system more efficient and stable.

2. Engineering machinery

In construction machinery, such as excavators, cranes, loaders, etc., cylindrical roller bearings are used to support and transmit loads.Due to their high load-bearing capacity and impact resistance, cylindrical roller bearings can meet the high-strength and high-load working requirements of construction machinery.

3. Mining machinery

In mining machinery, cylindrical roller bearings are mainly used in mining equipment such as crushers, conveyors, and elevators.These equipment often need to work in harsh environments, so they require bearings with high load-bearing capacity and wear resistance to support and transmit loads.

4. Textile machinery

In textile machinery, cylindrical roller bearings are mainly used in weaving machines, spinning machines, and other equipment.These devices require high-speed operation and bear large loads, and cylindrical roller bearings can meet these requirements and improve the stability and efficiency of the equipment.

5. Automotive industry

In the automotive industry, cylindrical roller bearings are mainly used in the steering system, suspension system, transmission system, and other parts of the car.These parts need to withstand large loads and shocks, and cylindrical roller bearings can provide stable support and transmission torque, improving the driving performance and safety of the car.
