Insulation on the inner ring Bearings FAQS

QWhat is INSULATED BEARINGS?

AElectrically insulated bearings using special spraying process, the outer surface of the bearing sprayed coating quality, strong film and the substrate with good insulation properties, can avoid galvanic action of induced currents on the bearings, grease and prevent current rolling bodies raceway damage caused to improve bearing life. This process is continuously improved, the insulating bearing, a layer 100μm thick coating, can withstand the maximum DC voltage of 1000 V in the outer or inner ring surface. Special spray process may be formed to a thickness uniformity, strong adhesion of a uniform coating, and subjected to further processing, it can influence from moisture and humidity.

QWhat are THE PRODUCT CATEGORIES OF INSULATING BEARINGS?

ADeep groove ball bearings electrically insulating the electrically insulating angular contact ball bearings electrically insulating cylindrical roller bearing inner or outer ring bearing with an insulating oxide coating is mixed with an electrically insulating ceramic bearing rolling elements

QWhat are THE ADVANTAGES OF INSULATING BEARINGS?

AElectrically insulated bearings to avoid corrosion damage caused by electricity, compared with an ordinary bearing applications in motors can guarantee more reliable. And compared to other insulating methods, such as the shaft or housing insulation, more cost-effective and reliable. Dimensions of insulated bearings and technical characteristics and substantially the same as the non-insulated bearings, one hundred percent and therefore interchangeable. For motors, generators, especially variable frequency motor applications more widely.

QWhat is THE SIZE RANGE OF INSULATING BEARINGS?

A1, the electrically insulating groove ball bearing diameter size range: 40mm ~ 140mm diameter size range: 80mm ~ 300mm Width range: 18mm ~ 62mm 2, angular contact ball bearings electrically insulating the inner diameter size range: 40mm ~ 140mm diameter size range: 80mm ~ 300mm width range: 18mm ~ 62mm . 3, the electrically insulating cylindrical roller bearing inner diameter range: 45mm ~ 140mm diameter size range: 100mm ~ 300mm width range: 25mm ~ 62mm
