Rotary bearing is an important mechanical component used to support and rotate shafts, which is usually used in industrial equipment, ships, automobiles and construction machinery. It is mainly composed of an inner and outer ring, a rolling body and a cage, and realizes the rotation and support of the shaft by rolling between the inner and outer rings of the rolling body. The design and selection of rotary bearing have an important influence on the stability, reliability and operation efficiency of the equipment.

Construction machinery is the mechanical equipment used in the fields of construction, mining, road construction, etc., the operation frequency is high in the process of use, the vibration is large, and the bearing bears the heavy load work from all aspects.

Features: Railway bearings have the characteristics of high bearing capacity, wear resistance, impact resistance, high temperature resistance, long life and so on.

Double row angular contact ball bearings, from automotive hub bearings series a high load capacity, high roll stiffness, double sealCorrosion protection machined bearing housing2. Threaded pin with positioning surface3. Lock washer4. There are high-performance three-lip box seals on both sides of the bearing to prevent pollution.

Construction machinery bearings are widely used in various products. The following are some common construction machinery products and their bearing applications:Excavators: Excavators are heavy construction machinery used to excavate earth, stone or other materials, which cover a variety of working conditions and load requirements. Roller bearings or plain bearings that work at high loads and high speeds are usually used on excavators.Bulldozers: Bulldozers are used to bulldoze land, fill earth or push other materials, and need to withstand a large pushing force.

Even if the production of the motor is strictly controlled during the manufacturing process, it is difficult to completely avoid the magnetic asymmetry of the armature and rotor. This asymmetry creates a voltage between the stators, which creates a current through the bearings, especially in AC motors. This current will cause corrosion pits, melting marks, electrical corrosion file lines and discoloration, wear and other damage on the bearing raceway and rolling surface.

Product Description:The main performance advantage of EG steel coil is good corrosion resistance and stamping performance, and the zinc layer can play a lubricating role to a certain extent, which is conducive to the forming of steel.

Product Description:The S275 carbon steel coil is made of rolled steel. This roll form is easy to store and transport and takes up relatively little space.

Product Description:The S235JR has a low carbon steel content and can be used in some non-critical parts of the vehicle, such as the interior panel of the carriage, spare tire frame, etc.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle.

Hub bearings can fix the tire and support the gravity of the whole body, provides precise guidance for the rotation of the hub. wheel hub bearing enables the wheels and attached components to rotate smoothly and keeps the wheel attached to the car. High quality wheel hub assembly make you enjoy your vehicle in a safe and smoothWheel bearing assemblies manufactured by high-quality materials for ensuring precisely matches, durability, reliability and premium performance.

Agricultural bearings are used in conveyors, lawn mowers, combines, hay balers, planters/grain drills, augers, cotton strippers, and more.  They are designed to stand up to extreme conditions and loads.  There are many different designs available.  Their basic components are inner and outer rings, balls, and retainers.  The inner race can be round, square, or hex, and the outer race can be either cylindrical or spherical.  Most agricultural bearings are sealed on both sides with single, double, or triple lip.New domestic modelsOld domestic modelInner diameter (mm)Outer

Bearing seat is a mechanical part for mounting bearings, which usually has two parts: a seat body fixed on the machine tool and a bearing seat sleeve fixed with the seat body. The role of the bearing seat is to support the bearing and ensure that the bearing can be correctly installed on the shaft of the machine equipment to withstand the load brought by the bearing in the rotating motion.The bearing seat is usually made of a high-strength metal or steel material to ensure that it has sufficient strength and stiffness to support the bearing.

Product Description:S350GD Galvanized Steel Coils are premium-grade steel products, characterized by their enhanced formability and structural integrity. These coils are specifically designed for applications requiring high tensile strength and resistance to environmental corrosion.

Product Description:Galvanized is the key surface treatment of the product, hot dip galvanized layer can effectively prevent steel rust and corrosion, improve the durability of the anti-skid in wet, corrosive environment. There are a variety of thicknesses to choose from, such as the common thickness range from 2mm-8mm to meet different load requirements.

Because the bearing ball is in contact with the bearing point, the load is small.

Product Description:The surface has a typical checker pattern, which is produced by a special pressing die during the sheet forming process.

Product Description:The 6082-T6 Aluminum Pipe is recognized as a medium-strength alloy with exceptional corrosion resistance, making it the highest strength alloy in the 6000 series.

Product Description:3003 aluminum rod is the main material of building doors and Windows, curtain wall frame. Its good corrosion resistance and machinability make the doors and Windows and curtain walls produced not only beautiful, but also durable.

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.

NTN angular contact ball bearings are suitable for a wide range of industrial equipment and machinery, including but not limited to the following applications:Machine tools and CNC equipment: used to support spindles and other rotating parts to ensure high precision and high-speed stable operation of the equipment.Automobile and motorcycle: widely used in engine, transmission system, suspension system and other components to ensure the smooth running of cars and motorcycles.Construction machinery: such as excavators, cranes, bulldozers, etc., used to withstand the huge load and bumpy vibration

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