Silicon Nitride (Si3N4) Ceramic Seal Rings And Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temeratures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitirde is non-porous, non-magentic, non corrosive, lighter than steel and, in ball form, is harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.

Q1: How to send an inquiry
You can send your drawing with technology requiremens,and infrom your purchase quantity .If you can,pls inform what is your part used in .We will confirm what is the most suitable materials and quote our best price to you in 24 hour
Q2:Can you provide the free sample
Yes,we can provide the sample free of charge if we have the stock product as customer's required,but the courier fee be collected
Q3:How long will it take for you to send me a quote?
This depends on the complexity of your requirements. For simple items such as plates and rods, we can generally supply a quotation within 24 hours.
Q4:What's the delivery time?
For the standard products, like ceramic substrate and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30-45 working days.
