Carbide and stainless steel are two common materials used to manufacture bearing balls. Each has its own unique properties that make it suitable for different applications.

stainless steel bearing balls are made from a type of steel that contains a high level of chromium. This makes them resistant to corrosion and rust, which makes them ideal for use in applications where moisture or chemical exposure is a concern. Stainless steel balls are also known for their high precision and smooth surface finish, which makes them ideal for use in high - precision applications.

Carbide bearing balls are high - performance balls made from tough and sturdy tungsten carbide material. Though carbide balls are generally more expensive than stainless steel balls and may not be necessary for all applications, they offer higher hardness and wear resistance, which enable them well - suited for use in extreme conditions such as high temperatures and pressure.

Tungsten carbide bearing balls are commonly utilized in various bearings. Their excellent precision and wear resistance allow the bearings to perform consistently and last a long time at high speeds. Carbide bearing balls are widely employed in precise manufacturing, aerospace, and other industries, and their importance is obvious.
