The main uses of conical roller bearings include the following aspects1. Construction machinery field: Conical roller bearings are widely used in all kinds of heavy construction machinery and equipment, such as excavators, loaders, bulldozers, road rollers, cranes, etc. These equipment need to withstand large axial load and radial load, and have high speed and accuracy requirements, cone roller bearings can meet these requirements to ensure the normal operation of the equipment.2.

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.

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 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.

NTN tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads, with high stiffness and rotation accuracy, and have large bearing capacity and low limit speed compared with angular contact ball bearings. Its carrying capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the carrying capacity.

There are two main types of bearings widely used in industrial robots: constant cross-section thin-walled bearings and RU cross roller bearings. The bearing of an industrial robot is one of the key components suitable for the joints of industrial robots or the turntables of machining centers, robots, medical devices, measuring instruments, IC manufacturing equipment, etc., and has a wide range of uses.

Combined needle roller bearings, a special type of bearing, can be added between the inner and outer rings of the needle roller components to achieve balance accuracy, reduce vibration and noise effects.

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.

Needle roller bearing is a common mechanical part, which is mainly used to support the movement of the rotating shaft. The working principle of the needle roller bearing is to use the rolling body (needle roller) to roll between the inside and outside, thereby reducing friction and resistance, so that the bearing can withstand larger loads and rotational speeds.The structure of the needle roller bearing is relatively simple, consisting of an inner ring, an outer ring, a needle roller and a cage.

Axial (Thrust) needle roller bearings are units comprising axial needle rollers and cage assemblies and axial bearing washers with a centring spigot. Axial (Thrust) needle roller bearings are able to accommodate heavy axial loads. They are insensitive to shock loads and provide a high degree of bearing units stiffness within a minimum axial space. They represent unidirectional bearings and can accommodate axial loads acting in one direction only.Using axial (thrust) needle roller bearings, it is possible to make compact bearing units.

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

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.

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.

Iko tapered roller bearings have high load bearing capacity and wear resistance. Because of the conical roller design, the bearing can share the load evenly when bearing heavy loads, and the bearing capacity is effectively improved. At the same time, the use of high-quality materials and advanced manufacturing technology to ensure the bearing's wear resistance and extend the service life.Iko tapered roller bearings have high rotation accuracy and running stability.

Product Description:Aluminized steel coil has good processability. It can carry out stamping, bending, cutting and other mechanical processing operations. During the stamping process, the aluminum plating layer can maintain good integrity and will not flake off easily.

Cam Follower Needle Roller Bearings are also referred to as track follower. They are designed to follow a sliding or rotating piece (cam) and they use rollers or needles as the rolling elements. Cam Follower Bearings are therefore able to replicate a specific motion because they are highly versatile. They have thick-walled outer rings that run on a track.

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.

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.
