NN3032K Cylindrical Roller Bearings-manufacture,factory,supplier from China

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.

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.

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.

1.Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations, which can withstand heavy loads and vibration loads without difficulty.2. this kind of bearing can bear a large axial load in a single direction, but can not bear radial load, they do not have automatic aligning ability.3. the thrust cylindrical roller bearing can be divided into thrust cylindrical roller and cage assembly, shaft ring and seat ring.4.

The design of the roller and raceway contact line of all thrust cylindrical roller bearings is optimized to avoid the generation of edge effects.

Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations that can withstand heavy loads and vibration loads without difficulty. Such bearings can withstand large axial loads in a single direction, but they cannot withstand radial loads, and they have no automatic aligning capability.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

Thrust tapered roller bearings can form a very compact bearing configuration, which can withstand very heavy axial loads, is not sensitive to impact loads, and has good rigidity. LYTBZ produces unidirectional tapered roller bearings and bidirectional tapered roller thrust bearings. The screw fixed bearing constitutes a specially designed unidirectional tapered roller thrust bearing and is filled with rollers.Thrust tapered roller bearing features:This bearing is used for rolling mill screw fixed bearing configuration.

Loaders: Loaders are used to load and unload various materials, and their working conditions require the wear and impact resistance of bearings. Cylindrical roller bearings or bi-directional thrust ball bearings that are resistant to high speed work are usually used on loaders.Cranes: Cranes are used to lift and move heavy goods and are required to withstand high tensile and compressive loads.

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

The structure of the thrust roller bearing is generally composed of an inner and outer ring, a thrust roller, a cage and a sealing ring. The inner and outer rings are annular structures, which are installed on the shaft and the housing to carry the axial load. The thrust roller is cylindrical or conical, arranged between the inner and outer rings, and can effectively withstand and transfer the axial load. The cage is a structure that supports and holds the thrust roller, usually made of steel or copper.

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high.

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.

Needle roller bearing is a common rolling bearing, using needle roller as the rolling body, can withstand the radial and axial load.Structure: Needle roller bearings are mainly composed of outer ring, inner ring, needle roller, cage and seal. The shape size of the needle roller bearing is small, saving space, suitable for limited space design.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

CAM bearing is a kind of bearing, with a thick outer ring needle roller bearing and bolt combination structure; The bearing bolt is provided with X oil passage; The outer surface of the outer ring has a cylindrical shape and a spherical shape, which can be selected according to the actual application; Eccentric type can easily and accurately adjust the axis position of the bolt when installing the bearing, etc., generally used in automotive camshafts (is the shaft that controls the opening and closing action of the X-type engine valve)1, thick outer ring needle roller bearing and bolt combinat
