Product Introduction

Silicon nitride ceramic ball is a precision ceramic sintered at high temperature in a non-oxidizing atmosphere, with high strength, high wear resistance, high temperature resistance, corrosion resistance, acid, alkali resistance, can be used in seawater for a long time, and has a good electric and magnetic performance. At 800℃, the strength and hardness are almost unchanged, and the density is 3.20g/cm3, which is almost 1/3 of the bearing steel. Weight, small centrifugal force in rotation. Can achieve high speed operation. It also has self-lubricating properties, and it can be used in environments with high pollution without lubricating media. Become the first choice for ceramic bearings, mixed ceramic ball bearings.

Application

1.Aerospace: Bearings for high-temp applications like turbines.

2.Electric Vehicles: Precision bearings in electric vehicle motors.

3.Manufacturing: Bearings in high-speed automated machinery.

4.Renewable Energy: Bearings in solar tracking systems and wind turbines.

5.Dental Equipment: Utilized in high-precision dental drills and other instruments.

6.Motors: Silicon nitride balls are ideal for motors. Its insulation properties prevent premature bearing failure due to electrolytic corrosion.

7.Semiconductor manufacturing: These balls play a key role in semiconductor devices. Because they are non-magnetic, they do not cause interference when dealing with high speeds, low lubrication and magnetic fields.

8.Wind power: In wind turbines, silicon nitride balls are favored for their durability and low maintenance needs. They help reduce the frequency of unplanned maintenance.

9.Automotive and bicycle applications: Silicon nitride balls are used in high-performance automotive parts and bicycle wheels. They have low friction and light weight for improved efficiency and performance.

10.Hybrid and all-ceramic bearings: These balls are commonly used in hybrid and all-ceramic bearings, especially in ultra-high-speed applications such as aerospace and defense.
