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.

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.

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.

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.

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

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.

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.

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.

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.

The popular riding machine for a stud kind cam follower is a slot, for use with a flat head screwdriver. However, hex sockets are accessible for greater torquing ability, which is specifically beneficial for eccentric cam followers and these used in blind holes.

Railway Bearings play an important role in both passenger and goods transport.  They have to withstand heavy loads: they work at high speeds, under a great weight, are  Rolling bearings in railway gearboxes must withstand a wide variety of operating conditions and complex environmental influences. Not only are high static and, in particular, dynamic loads present in the form of vibrations and shocks, but the rolling bearings are also operated intermittently below the permissible minimum load.

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 outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e.

The sliding bearing seat is composed of an upper cover, a base, a split bearing bushing (aluminum bronze) and mounting bolts, which mainly bear radial load. Easy to use, no need to install bearings. The load-free part of the inner surface of the bearing bush is provided with an oil groove, and the lubricating oil flows into the gap through the oil inlet hole and the post groove.

The working principle of the rolling bearing with seat is mainly to rely on the rolling body to roll in the groove of the inner and outer rings, and convert the input rotating force into rolling motion, so as to support and transfer the load. Compared with plain bearings, rolling bearings with seats have less friction and higher transfer efficiency because they reduce rolling friction.

Hub bearing unit 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.

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.

Bearing capacity: NTN angular contact bearings have high bearing capacity and can withstand large radial and axial loads. In the process of use, the axial load of the bearing will cause the contact pressure between the inner and outer rings to increase, so it is necessary to choose the appropriate contact Angle to improve the bearing capacity.Rotation accuracy: NTN angular contact bearings have high rotation accuracy, which can ensure that the mechanical equipment has stable rotation performance during operation.
