Insulated Bearing-manufacture,factory,supplier from China

The process has been continuously improved, and in insulated bearings, there is a coating 100μm thick on the surface of the outer or inner ring, which can withstand voltages up to 1000 V DC.

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.

The insulated bearing is a specially designed bearing whose internal structure can effectively isolate the external environment and prevent conductive and conductive heat. Insulated bearings are usually used in special industrial environments or in equipment requiring special protection.Structure composition: The insulated bearing is composed of an inner ring, an outer ring, a rolling body, a cage and a seal.

Inner and outer ring design: The internal and outer rings of the insulated bearing are made of insulating substances or different treatment, so that the modern-day interior the bearing can now not be carried out via the internal and outer rings, so as to reap the impact of electrical insulation.Seal design: The seal format of the insulated bearing is strict, which can efficaciously forestall the infiltration of exterior media and preserve the insulati

Inner and outer ring design: The inner and outer rings of the insulated bearing are made of insulating materials or special treatment, so that the current inside the bearing can not be conducted through the inner and outer rings, so as to achieve the effect of electrical insulation.Seal design: The seal design of the insulated bearing is strict, which can effectively prevent the infiltration of external media and maintain the insulation performance and stability of the bearing.

Some typical insulating bearing materials include ceramic, graphite and the famous polytetrafluoroethylene (PTFE). Ceramics are widely used in the bearing industry because of their hard diamond, wear-resistant gold and outstanding insulation properties. Graphite is widely used in bearings because of its extremely low friction and high lubrication. PTFE is widely used because of its excellent corrosion resistance and strong insulation. According to actual needs, designers and engineers can also choose other special materials to build insulated bearings.

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.

Advantages: The insulated bearing has good insulation performance, which can effectively isolate the external environment, improve the service life and stability of the bearing, and effectively avoid damage and failure caused by current conduction.Installation precautions: When installing insulated bearings, it is necessary to pay attention to keep bearings clean, lubricated and correctly positioned to ensure their normal operation and service life.

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.
