Ceramic ball bearings

In the chemical industry, with the food production and in pharmacy liquids assigned which mechanical engineering parts to affect aggressive could. Those are for example salt solutions, acids, disinfection and cleaning agent antifriction bearings made of high-grade steel advisablely here fast to your borders, since the used high-grade steels already already corrode with the contact with salt solution. In order to supply the camps with lubricant is it necessarily these complex to be sealed. Seals limit additionally the number of revolutions and lower the possible application temperature. Ceramic antifriction bearings however are suitable due to your material properties for medium lubrication and for the unlubricated operation. Thus special application type in the hygiene range, the food, pharmaceutical industry as well as the medicine, pure space and vacuum engineering are opened. Advantages of ceramic antifriction bearings: - Extreme high light running properties by small friction maintenance arm or maintenance-free lower wear and thus higher life span up to 60% smaller weight small centrifugal force high one chemical stability (corrosion resistance, insensitivity to wetness) - high ones hardness and rigidity no reciprocal effect with magnetic fields, because nonmagnetic is high temperature stability-preferential material for ceramic camps silicon nitride (Si3N4). It is easily, high-strength and wear resistant. The economical alternative for this is zircon oxide (ZrO2), its thermal expansion coefficient resembles that of the steel. Shrink fits are not necessary thus, since no fit problems can occur by different thermal expansion. High-grade steel camps can also later be exchanged thus by zircon oxide camps. NovoNox, the expert for stainless components, extends a further mark the assortment, which covers now over 4.000 parts with the ceramic antifriction bearings. Norbert Hildebrandt, technical advisor with NovoNox: � we saw simple that with antifriction bearings a large demand exists, which we would like to cover now with products of our program. � �
