The Insulation Problems Of Hybrid Ceramic Bearing

Release time : 2015-06-10 09:15:31
The normal assembly of Hybrid Ceramic Bearing: Inner and outer ring of Chrome bearing + Zirconia ceramic ball/ Silicon nitride ceramic balls Inner and outer ring of Stainless steel + Zirconia ceramic ball/ Silicon nitride ceramic balls The assemblies above can solve 2 problems: 1, improve revolving speed 2, widen use duration But a bearing consists of 4 parts: inner and outer ring, ball, holder, dust cover. So how to make Hybrid Ceramic Bearing insulated like Full Ceramic Bearing? The demand of insulation is that there is no link between inner and outer ring, the core of the problem is on the holder. The use of holder: to insulate the movements of rolling element and guide roller. But when the holder is golden, then the inner ring will bump the outer ring, the bearing will be conductive, this would break the partial meaning of Hybrid Ceramic Bearing. The following are customer's requirements: 1, Due to bearing's high revolving speed, the noise demand must be in Row Z2 . 2, The bearing in the the centre of magnetic field, it revolves flexible. 3, The use duration is is longer 2/3 than the former Full Metal Bearing. From the bearing meet the requirements above we can know the match: Hybrid Ceramic Bearing+ Nylon Holder +Rubber Cover +Oil/oil free dry baking
