Cross Roller Cylindrical Roller Bearing-manufacture,factory,supplier from China

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.

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.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

Cross roller bearing is a special kind of rolling bearing, which is widely used in mechanical field. It is designed to meet large size equipment that needs to operate under the requirements of high load capacity, high rigidity and high rotational accuracy. The cross roller bearing is composed of inner and outer rings, rollers, sealing rings and cages, and its structural advantages are that it can withstand both radial and axial loads, with high torque rigidity and running accuracy. The following will introduce the characteristics and applications of cross roller bearings in detail.

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.

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.

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.

Bearing performance: The bearing capacity of cross roller bearings is large, suitable for high-speed and high-load applications. Due to the special arrangement of rollers, the bearing can share part of the load when bearing radial and axial loads, which improves the bearing capacity and stability.

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

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.

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.

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.

This type of bearing is widely used in industrial automatic robots, working machinery and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.

Thrust roller bearings have the following application characteristics:Withstand large axial load: thrust roller bearings are suitable for mechanical equipment that needs to withstand large axial load, and have high carrying capacity and stability.High-speed rotation: thrust roller bearings can provide good support and smooth operation when rotating at high speed, suitable for fast equipment.Long service life: Because thrust roller bearings can effectively reduce friction and wear, they have a long service life and reliability.Easy installation and maintenance: thrust roller bearings have simpl

 Deep Groove Ball Bearings Deep Groove Ball Bearings are highly versatile and extensively used in various industries due to their ability to support higher radial loads and moderate axial loads.

High temperature resistant bearing: The material itself has resistance to high temperature 1200 ℃, and good self-lubrication, tem- perature between 100℃ to 800℃ should not produce temperature difference caused by the expansion.

In rolling bearings, the bearing ring is separated by a rolling unit (rolling element), and in slide guidance systems, the movable part slides on a static guide rail or shaft. Depending on the type of track system, the sliding layer is on movable or rigid components. The lubricating oil is embedded in the sliding layer to achieve lubrication. INA linear plain bearing is a linear positioning bearing with infinite stroke length.

The unidirectional thrust ball bearing comprises a shaft ring, a seat ring and a ball-cage assembly. It can be separated and the shaft ring, seat ring, ball-cage assembly can be installed separately. Unidirectional thrust ball bearings can withstand the axial load in a single direction and can be positioned in a single direction, but must not bear any radial load.The 51130 belongs to the single direction thrust ball bearings, also called ball thrust bearings or axial deep groove ball bearings. These bearings consist of a shaft ring, a housing ring and a ball and cage assembly.
