nine star provides bearings with oxide ceramic insulating layers on the bearing ring. applied with plasma technology, the insulation has a guaranteed breakdown resistance of at least 1000v ac or dc. this kind of insulated bearings are mainly used in traction motors of railway vehicles, electric motors and wind turbine generators. it can avoid the electric pitting in bearings by preventing electric current, so to improve the service life of the bearings.

such series brass cage could be subdivided into three types: m, ma, mb. m type structure is guided by steel balls, it's advantages are low noise, high speed, long life, small friction coefficient, but is not suitable for strong impact and violent vibration. ma is guided by outer ring. its advantage is high speed, long life, withstand higher speed, environmental vibration and impact to bear ability is better than m type. mb structure is guided by inner ring, its advantage is running good with low speed, strong stability. brass solid retainer mutual advantages are as following: high temperature, rubbing resistant, reliable, long lifetime.

the steel cage is most widely applied in the deep groove ball bearings, commonly used in heavy machinery, metallurgy, mining, automotive, electrical instrumentation, engineering machinery, and others. it’s advantages are low noise and flexible rotating. however, it is not suitable for big vibration and high temperature.

the bakelite cage has high mechanical strength, good corrosion resistance, anti-rust, heat resistance and lubricity. meanwhile, it possesses light-weight, strong-strength, and other irreplaceable usages. it’s mainly applied in light load and low noise working environment, such as air conditioning compressor, high performance pump ect.

insulated deep groove ball bearings generally have two types: the inner insulation coating insulated bearings and the outer coat insulated bearings. the basic coating can withstand voltages up to 3000 volts ac or dc. however, according to customer requirements supply 500v-3000v dc coating. one can refer to international suffix (vl0241 & vl2071, j20aa, j20b, j20c, sq77 & sq77e etc). applications mainly used in high-power electric motors, wind turbines, railway locomotive traction motors, variable frequency motors, generators and other occasions.

insulated cylindrical roller bearings generally have two types: the inner insulation coating insulated bearings and the outer coat insulated bearings. the basic coating can withstand voltages up to 3000 volts ac or dc. however, according to customer requirements supply 500v-3000v dc coating. one can refer to international suffix (vl0241 & vl2071, j20aa, j20b, j20c, sq77 & sq77e etc). applications mainly used in high-power electric motors, wind turbines, railway locomotive traction motors, variable frequency motors, generators and other occasions.

capable of taking high radial loads and axial loads in a single direction, insulated tapered roller bearings are available in single, double and four row versions to support axial loads in either direction. optimised designs can be supplied with high strength cages and, for arduous applications, in a range of advanced special materials. the taper angles allow the bearing to handle a combination of radial and thrust loads. the steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.

insulated spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. the centre point of the sphere in the outer ring raceway is at the bearing axis. therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. insulated spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.

insulated self-aligning ball bearings are constructed with the inner ring and ball assembly contained within an outer ring which has a spherical raceway for self aligning. insulated self-aligning ball bearings are particularly suitable for applications where misalignment occurs from errors in mounting or from shaft deflection.

insulated angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. this means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. the axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. the contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

hybrid ceramic bearing is a chrome steel material rings combined with bearing level silicon nitride (si3n4) rollers. because of the excellent electrical insulation properties of silicon nitride, such type bearings’ application is applied to motors as insulation bearing and shaft. type classification: single row deep groove ball bearings, single row cylindrical roller bearings, hybrid ceramic angular contact bearings, hybrid ceramic stainless steel bearings. applications: motors, generators, wind turbines, and other special environment.
