The obvious choice for modern electrical motors
CeramicSpeed Insulate ball bearings are custom-made for electrical motors and guarantee against damage caused by stray currents. The ceramic balls used for the CeramicSpeed Insulate series are non-conductive and have an insulating ability of 15 kV per mm - higher than that of atmospheric air.
We deliver our Insulate series in a variety of combinations - if you can't find the one that fits you please contact us and we will find the right solution for you.
Does CeramicSpeed Bearings have lower energy consumption?
Compared bearing to bearing, we have documented 48% lower friction in our own CeramicSpeed Hybrid Bearing compared to similar sized premium brand steel bearings. In an electrical motor, this reduction in bearing friction yield a measurable increase in overall motor efficiency and resultantly a reduction in energy need and a reduction of CO2 emissions.
Are CeramicSpeed Ceramic Balls non-conductive?
Bearings from competing manufacturers with an insulating coating typically have an insulating ability of up to 1 kV; provided that the coating is not damaged - for example when the bearing is mounted. In practice this protection isn’t always sufficient, meaning that these bearings are also vulnerable to damage by stray currents. The ceramic balls used for our Insulate product series are non-conductive and have an insulating ability of 15 kV per mm - higher than that of atmospheric air.
In addition to being protected from the passage of electrical currents, the operating temperature is 10-20°C lower, and the result is a bearing life typically 4-8 times longer than traditional steel bearings.
