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.

Q1: How is your quality ?Â
A1:Good quality. ISO9001:2008 certificate to ensure the quality.
Q2: Can you privide free samples?
A2: Sample is free (except large bearings),and postage should be paid by buyer. But postage can be refund after order is confirmed.
Q3: What's your brand and service?
A3: We have our own brand  in China with brand SPD
A3: We supply OEM service and after sales service
Q4: What is the Warranty for the bearings?
A4: For the bearings,we have 1 years warranty. If any quality problems on our side occured in this period ,we will take on the shipping cost and replacement.
Q5: Is there any cheap shipping cost to import to our country?
A5: For small order,express will be best.And for bulk order,sea ship way is best but take much time.
