Double Row Cylindrical Roller Bearings-manufacture,factory,supplier from China

According to whether the ring has a rib or not, NSK cylindrical roller bearings are divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN double-row bearings. The bearing is a structure with separable inner ring and outer ring. Cylindrical roller bearings with inner or outer rings without rims, the inner and outer rings can be axially moved relative to each other, so they can be used as free-end bearings.

Railway shaft double row tapered roller bearings have the following characteristics:High load bearing capacity: Double row tapered roller bearings are designed with two rows of rollers, so they can withstand large radial and axial loads.High temperature resistance: suitable for high-speed operation and high temperature environment, with good heat resistance.Strong aligning ability: can maintain good working performance when bearing installation is not accurate or axial displacement.Easy assembly and disassembly: double row tapered roller bearing structure is relatively simple, easy disassembly

Double-row tapered roller bearings have many advantages in structure and performance, so they are widely used in industrial production.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.237700090000.154302067206E306217.543.250.5600075000.231302077207E35721754.263.5530067000.331302087208E4080186374500063000.422302097209E45851967.883.5450056000.474

The different types of cylindrical roller bearings are designated based on their structural features and intended applications: N..EM: Cylindrical roller bearing with a standard inner ring without any ribs, suitable for radial loads. NU..EM: Bearing with aremovable inner ring and two integral flanges on the outer ring, designed for high radial loads and accommodates axialdisplacement. NJ..EM: Features a removable inner ring and one integral flange on the outer ring, primarily used for applicationswhere axial displacement is required.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

Double-row tapered roller bearings are usually used in applications that require large loads and high-speed rotation, such as wind turbines, metallurgical equipment, rolling mills and heavy machinery, etc.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

The range of four-row tapered roller bearings is wide, including not only the traditional design with an intermediate ring between the outer ring and/or the inner ring, but also the modification of the four-row tapered roller bearings with an integrated middle ring and the bearing ring.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.2377000900

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

The seal is an important protective part of the flange bearing, which can prevent dust, water vapor and other impurities from entering the bearing inside, while maintaining the stable state of the grease or lubricating oil inside the bearing to improve the service life and performance of the bearing.Generally speaking, flange bearings have the advantages of simple structure, easy installation, large carrying capacity, good wear resistance, etc., and are widely used in all kinds of industrial machinery and equipment, such as wind turbines, agricultural machinery and metallurgical equipment.

The deep groove ball bearing with dust cover and sealing ring has been filled with appropriate grease during assembly, and should not be heated or cleaned before installation. No further lubrication is required during use, and the operating temperature is between -30 ° C and +120 ° C.NSK deep groove ball bearings generally consist of two bearing rings with complete raceways. The rolling element is mounted between the rings and rolled on the raceway. The rolling parts can be balls, cylindrical rollers, needle rollers, tapered rollers, or barrel rollers.
