There are both domestic and imported silicon nitride balls in the industrial market. There are obvious differences in raw materials, processing technology, precision grade and price. Enterprises need to select products according to usage scenarios and budget.

Precision instruments such as optical detectors and miniature sensors need tiny high-precision rolling components. Micro silicon nitride balls with diameter less than 3mm have ultra-small tolerance and ultra-smooth surface, becoming the core accessories of miniature precision instruments.

Automobile transmission system bears frequent shifting impact and high-speed rotation. Traditional steel bearings are easy to heat and wear. Silicon nitride balls are used in automobile gearboxes and transmission bearings to improve transmission efficiency and durability.

Although silicon nitride balls have excellent wear resistance, long-term harsh working conditions will still cause different forms of wear failure. Mastering wear types and causes is conducive to optimizing working conditions and extending service life.

Incorrect installation will cause surface damage and precision loss of silicon nitride balls. Standardized installation steps can avoid artificial damage and give full play to the performance advantages of ceramic bearings. This article summarizes the universal installation guidelines for silicon nitride ball bearings.

Many industrial equipment such as hydraulic machinery and mining equipment work under ultra-high pressure. The pressure resistance of rolling balls directly determines equipment safety. Silicon nitride balls have excellent high-pressure resistance, which is inseparable from its internal crystal structure.
