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.

This bearing adopts ceramic rolling element (ball or roller) made of Si3N4 material; It has excellent insulation performance, its capacitance is basically 40pf, and the insulation performance is better than that of coated bearings. At high temperature, the DC impedance can also reach the range of G ohms, and has good insulation performance. Ceramic rolling element has excellent wear resistance and low lubrication requirement. Especially suitable for high-speed, low friction, low temperature operation; It works well under dry friction conditions.

Insulating materials: insulated bearings are usually made of insulating materials, such as ceramics or special alloys, whose insulation properties can effectively prevent the current from being transmitted through the bearing to other components and play a protective role.Application: insulated bearings are widely used in electrical equipment, motors, generators, frequency converters, wind turbines, electric vehicles and other fields, especially suitable for occasions that need to prevent current conduction.

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.

The sealing and protection of truck bearings are also very important. Trucks often drive in a variety of harsh road conditions, bearing in dust, water vapor and chemicals and other corrosive environment. In order to extend the life of the bearing, it is necessary to take into account the sealing property in the design, and select the appropriate sealing material and structure.Truck bearings also have certain requirements on installation and maintenance. Proper installation and proper lubrication are the keys to ensure the normal operation of truck bearings.

The main role of wheel bearings is to bear the weight and provide precise guidance for the rotation of the wheel, which is subject to both axial and radial loads. Traditionally, bearings for automotive wheels are made of two sets of tapered roller bearings or ball bearings combined, and the mounting, oiling, sealing and clearance adjustment of the bearings are carried out on the automotive production line.

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.

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.

The DAC type auto front wheel bearing is a double row angular contact ball bearing incorporating an integral outer ring and two separable inner rings; which is available either with seals or without seals. Wheel bearings (hub bearing) main role is to load and for the rotation of the hub to provide accurate guidance, both axial load radial load again, is a very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearings combination, bearing installation, oiled, and adjust the clearance seals are conducted in automotive production line.

Truck hub units, which contain two tapered roller bearings, are pre-adjusted, greased and sealed at the factory in order to simplify installation. The wheel bearing units are intended for use in truck, trailer and buses. They are designed to withstand typical harsh operating conditions and require less maintenance than the conventional wheel bearing sets they replace. Some variants have an integrated impulse ring which makes some variants suitable for use with anti-lock braking systems.

Features: (1) High strength and wear resistance: wheel bearings are usually made of high-strength alloy steel or stainless steel, with good wear resistance and pressure resistance, can withstand the high load and friction when the vehicle is running; (2) Good sealing: the seals in the hub bearing structure can effectively prevent external dust, water, impurities, etc.

Advantage of 7020C BearingWhen using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.The locking port of this kind of bearing is on the outer ring.Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction.The ability to bear axial load is determined by the contact angle.The larger the contact angle, the higher the ability to bear axial load.Angular contact ball bearings are mainly divided into single row angular contact ball bearings and double row angula

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.

A flange bearing is a bearing widely used in industrial machinery, which has a flange (usually circular) to be fixed in the mechanical equipment. The flange bearing consists of an inner ring, an outer ring, a rolling element (such as a steel ball, roller, roller, etc.), a cage and a seal.First of all, the inner ring and the outer ring are the main bearing parts of the flange bearing, they are usually made of high-quality steel, after a good heat treatment process to ensure their hardness and wear resistance.
