Linear motion bearings have the characterized of smooth movement,low friction,high rigidity and long life span,economical and easy to maintain or replaceMotorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand.

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

Linear bearing is a linear motion system used for linear stroke and cylindrical shaft.

Flanged linear bearings can also withstand large loads and moments. Its internal structure has been precisely designed and made of high-strength materials to maintain stability under high speed and high load operating conditions. Therefore, in heavy machinery equipment and construction machinery, flanged linear bearings are often used to withstand the weight of goods and the inertial force brought by movement to ensure that the mechanical system is always in a safe and stable state.The role of linear bearings mainly includes support, guidance and load bearing.

The sealing structure of the flange bearing is indeed crucial, because it can effectively protect the inside of the bearing from the intrusion of external impurities, thereby reducing the wear and failure of the bearing. Choosing the appropriate sealing structure can improve the reliability and stability of the equipment and extend the service life of the bearing. If you have any questions about the sealing structure or bearing performance, please continue to communicate with me.

Product Description:A36 carbon steel is a kind of low carbon steel, with good toughness, can withstand a certain impact and dynamic load, will not easily brittle fracture. Widely used in building structure frame, such as beams, columns and so on.

Structure: Railway bearings are generally composed of inner ring, outer ring, rolling body and cage and other components. The inner ring is directly connected to the shaft, the outer ring is installed on the wheel, and the rolling body is located between the inner and outer rings, which reduces friction through rolling and maintains the normal operation of the bearing.

The separation bearing is composed of a racetrack ring, a needle roller and a cage assembly, and can be used in any combination to thin or thick racetrack rings. The non-separable bearing is an integral bearing composed of precision stamped raceway ring, needle roller and cage assembly that can withstand unidirectional axial loads. This bearing occupies a small space, which is conducive to the compact design of the machine.

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

UBC bearings enjoy a high reputation in the international market, and their products are widely used in mechanical engineering, automotive industry, power industry and other fields.UBC bearings have a wide range of product lines, including deep groove ball bearings, tapered roller bearings, cylindrical roller bearings, angular contact ball bearings and other types of bearings. The characteristics of these products include high speed performance, strong wear resistance, long service life and other advantages, and are widely used in various industrial fields.

The important measure to reduce automobile fuel consumption is to design low friction torque hub bearings, and the main factors affecting the bearing friction torque is the type of bearing and preload, and the bearing seal accounted for a large proportion of the friction torque components. Therefore, improving the seal design to reduce the friction torque can significantly improve the performance of hub bearings.

The main features of rotary support bearings include high bearing capacity, fast speed, small friction, wear resistance, simple structure, easy installation and so on. It can withstand large axial and radial loads, while having high rigidity and accuracy, suitable for high-speed rotation and precision positioning requirements. Different types of rotary support bearings have differences in structural form and working principle, such as four-point contact ball type, two-way thrust ball type, cross roller type, tapered roller type and so on.

Retentors, usually made of steel or synthetic materials, are used to hold rolling elements in position, ensuring that they maintain the correct clearance and position relationship with each other during use.Single-row angular contact bearings are suitable for all kinds of rotating machinery, such as automobile wheels, motors, fans, etc., which can withstand high-speed operation and large loads.When installing, it is necessary to pay attention to the cleaning and lubrication of the bearing to ensure its performance and life.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter

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.

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling surface can form a pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing because the rolling bus and the raceway bus of the washer converge at a certain point on the axis line of the bearing.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)294169039416801705446813802000–5.9129412903941260130422938542700—2.61294139039413651404534410002500—3.342

Agricultural engineering involves a wide range of machinery, equipment and tools, including tillers, tractors, rake machines, balers and high-power harvesting machinery such as green feed harvesters and combine harvesters. A variety of different mechanical equipment, also need to face the harsh working environment. The dusty conditions in summer have very high requirements for bearing seals. In addition, farming machinery bearings are usually integrated with flanged housings to simplify assembly.

Product Description:Hot-rolled carbon steel coils are made by rolling billets at high temperatures (usually heated to around 1000-1250 °C). Widely used in the manufacture of various mechanical parts, such as shafts, gears, connecting rods and so on.

The fourth generation hub bearing unit is to make the constant speed universal joint and bearing into a whole, which solves the defect of increasing the size of the hub due to the integrated structure of the hub and the constant speed universal joint in the prior art. The development of the fourth generation hub bearing unit has been successful, and it is believed that it will be widely used in various types of automobiles in the near future.

Construction machinery bearing is a mechanical component used to support and turn rotating parts. In construction machinery, bearings usually carry high-speed rotating parts, such as engines, transmission systems, etc. Bearings usually consist of an inner ring, an outer ring, a rolling element and a retainer.There are many types of construction machinery bearings, including rolling bearings and plain bearings. Rolling bearings reduce friction and improve rotation efficiency by rolling rolling elements (such as spheres, rollers or cylinders) between the inner and outer rings.

Thrust roller bearings are used to bear axial and radial combined loads based on axial loads, but the radial load shall not exceed 55% of the axial load.
