2.Description

Bearing NO.: 6904CE 

Brands :CLUNT/OEM

Materials : Si3N4, ZrO2, Si3

Cage Materials:  PTFE, nylon66, acyl of polyether imide, zirconia, silicon nitride, stainless steel

Features: Full Ceramic Si3N4 Material Bearings 6904CE 

Full ceramic bearing Si3N4 material has perfect propriety such like suitable for low and high temperatures, high load capacity, corrosion resistance, nonmagnetic insulated and self lubrication. Thus it suit for the specific applications which are not available for bearing steel and hybrid construction ceramic ball bearing materials.

Advantages: 

Firstly, the ceramic bearing has the feature of corrosion risistance, the ceramic rolling bearing suitable for operation under harsh conditions covered corrosive media.
Secondly, since the ceramic ball rolling has lower density than steel, so which is much lighter, so when you rotate the outer ring centrifugal effect can be reduced by 40%, thus greatly extended service life.
Thirdly, the expansion and contraction of the ceramic affected smaller than steel, and therefore the gap of the bearing is constant, the bearing allows the temperature changes more severe environment.
Fourthly, as the ceramic has higher modulus of elasticity than steel, when the force is not easy deformation, and therefore help to improve the operating speed and achieve high accuracy.

Applications: Ceramic bearings with the features of  high temperature, cold, wear resistance, corrosion resistance, magnetic insulation, oil-free self-lubricating, high-speed and other characteristics. Can be used in extremely harsh environments and special conditions, can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, pumps, medical equipment, research and national defense and military fields, is application of new materials, high-tech products.
