In order to ensure the performance and service life of rotary support bearings, it is necessary to pay attention to the following points: correct selection of suitable bearing models and specifications, reasonable design and arrangement of bearing bearings and lubrication systems, regular inspection and maintenance of bearings, timely replacement of severely worn parts, to avoid overload and overspeed operation, to prevent dust and dirt intrusion into the bearing interior.

The insulated bearing adopts a special spraying process to spray high-quality coating on the outer surface of the bearing. The coating has strong adhesion to the substrate and good insulation performance, which can avoid the electric corrosion of the bearing by the induced current, prevent the damage of the current to the grease, the rolling element and the raceway, and improve the service life of the bearing. The process is constantly improving. In insulated bearings, the outer ring or inner ring surface has a layer of 100μm thick coating, which can withstand voltages up to 1000V DC.

Excavator bearing installation and removal methods, should be according to the excavator bearing structure, size and excavator bearing parts with the nature.Installation, disassembly pressure should be directly added to the end face of tight fit excavator bearing stalls circle, not by the excavator bearing rolling elements to transmit pressure, because this will be caused by the excavator bearing work surface indentation, impact excavator bearing normal workeven make excavator bearing damage.

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.

 If the bearing seat is equipped with neutron control, pay attention to absolutely prohibit the joint phenomenon of the signal line between the die casting machine and the bearing seat, the reason is clear, in daily production, it is difficult to avoid water on the signal line, or the place where the joint is wrapped is easy to break, resulting in short contact with the machine tool, if the signal is wrong, the light alarm automatic shutdown delay time, the heavy signal disorder, Break the bearing seat. Cause unnecessary loss.

Product Description:Q215 carbon steel coil is one of the commonly used materials for manufacturing welded steel pipes. Through crimping, welding and other processes, carbon steel coils can be made into steel pipes of different diameters and wall thicknesses, which are widely used in water supply and drainage, gas transmission, heating pipes and other fields. It can also be used to manufacture various accessories in the pipeline system, such as elbows, tees, quads, etc.

Product Description:It is used in key components such as body structure and bogie of high-speed train. The high strength and good fatigue resistance of 7A04 and 7050 aluminum alloy can ensure the stability and safety of the train body when high-speed trains are confronted with huge air resistance, vibration and complex mechanical loads generated by high-speed running.

When the rotary help bearing is working, the internal and outer rings recognize relative rotation thru the aggregate of rolling elements. When the exterior pressure acts on the bearing, the load is transmitted to the internal and outer rings, and is transmitted to every different via the rolling element, attaining the carrying capacity.

Product Description:The base plate of HDG Steel Coil (hot-dip galvanized steel coil) is usually cold-rolled steel sheet or steel strip. HDG steel coil thickness range is wide, generally from 0.3mm-3.0mm between.

Agricultural FAFNIR Bearing insert bearing 203KRR2 203 RR2 203RR2 are with particularly thick-walled outer rings. In addition to high radial forces, these bearings can also support axial forces in both directions.The outer rings have a crowned or cylindrical outside surface.

Automobile hub bearing is one of the important parts of automobile, which plays the role of supporting wheel rotation and transmitting power. Below I will introduce the structure, function and characteristics of automotive hub bearings in detail.Structure: Automotive hub bearings are usually composed of several parts, such as an inner ring, an outer ring, a rolling element (such as a steel ball or roller), a cage and a seal. The inner ring is the part connected to the axle, and the outer ring is connected to the wheel.

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.

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.

In general, the rotary support bearing is an indispensable part of modern mechanical equipment, and its stability, reliability and life directly affect the operating efficiency and safety of the equipment. Therefore, in the process of engineering design and use, it is necessary to attach great importance to the selection, installation and maintenance of rotary support bearings to ensure the normal operation of the equipment and extend the service life.

Product Description:High carbon steel plates have a higher carbon content, usually between 0.60%-1.50%. Widely used in the manufacture of various cutting tools, such as cutting tools, saw blades, etc.

Hub bearing unit ball bearing is developed on the basis of standard angular contact ball bearings and tapered roller bearings, it will be two sets of bearings as one, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealing bearings can be loaded in advance grease, omit the external hub seal and free from maintenance and other advantages, has been widely used in cars, There is also a trend of gradual expansion of applications in heavy-duty vehicles.1.

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.

The series of products with flanges on the outer wheel make the axial positioning easy; The bearing seat is no longer needed and becomes more economical. In order to obtain low friction torque, high rigidity and good rotation accuracy of bearings, steel balls with small outer diameter are used. The use of hollow shafts ensures lightweight and wiring spaceThe biggest feature is that the flange and the bearing are integrated.

Flanged linear bearings can also play a guiding role. It can make the moving parts move according to the predetermined trajectory through the roller or slider set in its interior, avoiding deviation and shaking. For example, in machine tool processing, flange linear bearings are often used to guide the movement of the table to ensure that the cutting tool can accurately remove the coarse and fine, improving the processing accuracy.

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

The main role of automobile hub bearing is to load and provide accurate guidance for the rotation of the hub, which is a very important component to bear both axial and radial loads. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line.
