Product Features
Bearing the ZWZ production of electrical insulation using special spraying, spraying the outer surface of bearing the high-quality coated the coated substrate with strong, good insulation properties, to avoid the induced current electrical erosion of the bearing to prevent the current of the grease and the rolling element and raceway damage, improve bearing life. For motors, generators, inverter motor is more widely used.

 Products
And ZWZ production the following three types of electrical insulation bearing
Electrical insulation deep groove ball bearings
Electrical insulation angular contact ball bearings
Electrical insulating cylindrical roller bearings Tolerance
ZWZ electrical insulation bearing GB307.1 standard tolerances, special requirements may provide the appropriate level of tolerance.
Clearance
ZWZ electrical insulation deep groove ball bearings and cylindrical roller bearings GB4604 in the ordinary group of radial internal clearance, For other clearance, or upon request, to provide electrical insulation of the corresponding clearance bearing.
Cage
According to the different bearing series and size, ZWZ electrical insulation bearings fitted with the following cages:
Reinforced nylon 66 cage
Drawing Steel Cage
Machined solid brass cages
Cage Code logo can refer to the standard deep groove ball bearings, cylindrical roller bearings and angular contact ball bearings.
