Zirconia Grinding Beads Surface Polishing ZrO2 Ceramic G5 G10 Bearing Ball
Our factory specializes in the production and processing of zirconia ceramic products. Zirconia balls from 1-50mm, precision from grinding media to full ceramic bearing balls. Customization is also acceptable.
Material: Zirconia(ZrO2)
Zirconia oxide has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges.
Zirconia partially stabilised with either magnesia or yttria has excellent mechanical properties at high temperatures and is relatively inert to hostile environments. The ability to retain high strength at elevated temperatures and resist a range of molten metals makes it ideal for use as a crucible material.
Advantages of zirconia ball grind media
1) Preventing material from contamination because of its extreme low wear rate.
2) High grinding efficiency.
3) Lower total costs due to the long using life.
4)Suitable for high velocity operations and wet grinding operations.
Applications of zirconia ceramic
• Wire forming/drawing dies
• Insulating rings in thermal processes
• Precision shafts and axles in high wear environments
• Thermocouple protection tubes
• Bushings and caps
• Kiln furniture crucible
• Knives and blades
• Bearings & rollers
• Welding nozzles & pins

Answer: With the development more than 20 years, now we have 6 business division and we are supplying Quartz Glass (Tube,Rod,Plate and customized parts), optical glass and cuvette, and also various precise ceramics, porous ceramics and refractoryceramics. We have the full processing line for ceramic thick film resistors, far infrared ceramic glass heating panel, quartztube/ceramic plate ozone generator and porous metal fiber felt. For all the products, we can design and customize according to the clients’ demand.
2: Before mass order, can you offer samples? How will you charge for them?
Answer: We are willing to offer samples to lower your purchasing risk. Generally, if from inventory, we can deliver out within 3days, however if need processing, we can deliver out within 15 days. For some difficult items, the delivery time will be decided by its grade of difficulty. For some low value items, we can offer free sample, however we would like you to afford the freight cost. For customized products, we need to charge the developing cost.
3: What test report or certificate can you offer? What achievements have you made in research and development?
Answer: Till the end of 2021, we have passed many ROHS, CE, MSDS tests and also the ISO9001 authentication. We have 8 registered trademark and 25 patents. Also we won the title of China High-tech Enterprise and Jiangsu Private Science and Technology Enterprises.
4: Do you have any agent in our area? Can you export your products directly?
Answer: Till the end of 2021, we haven’t authorized any company or person as our regional agent. From 2008, we have the export qualification and professional export team, and till the end of 2021, we have exporting our products to more than 103 countries and regions, and our clients can contact us and purchase our products or service directly.
5: If the quality can not meet the requirement or any loss during the freight, how should we do?
Answer: We have strict QC test and professional QC team. We are always offering qualified products. If anything goes wrong, the quality can not meet requirement on the contract, we will reproduce the qualified products or refund the payment. We have the professional packing team and will pack the product in safe package for long distance delivery. If any loss during the freight, we hope you can assistant us to claim from the logistics company and we will arrange the replacement accordingly.
