Overview of High Temperature Resistance Hardness HRC 90 Silicon Carbide Ceramic Ball Bearing
Silicon Carbide (SiC) ceramic balls are spherical components made from high-purity silicon carbide, a synthetic ceramic material recognized for its exceptional hardness, wear resistance, and thermal stability. These balls are engineered to withstand demanding conditions, where conventional materials like steel or even standard ceramic balls may fail, making them invaluable in precision engineering and high-performance applications.
Features of High Temperature Resistance Hardness HRC 90 Silicon Carbide Ceramic Ball Bearing
-
Extreme Hardness: With a Mohs hardness rating close to diamond, SiC ceramic balls exhibit superior resistance to scratching and abrasion.
-
High Wear Resistance: Thanks to their hardness and low friction coefficient, they experience minimal wear, extending their lifespan in abrasive environments.
-
Superior Corrosion Resistance: Inert to most chemicals, they resist corrosion and degradation, even in acidic or alkaline conditions.
-
Thermal Stability: Retain their dimensions and mechanical properties over a wide temperature range, making them ideal for high-temperature operations.
-
Low Density: Being lighter than traditional metal balls, they reduce centrifugal forces and inertia in high-speed applications.
-
Electrically Insulating: Non-conductive nature allows their use in electrical and electronic applications requiring insulation properties.
-
Low Thermal Expansion: Minimal dimensional changes due to temperature fluctuations ensure consistent performance in precision applications.

Parameters of High Temperature Resistance Hardness HRC 90 Silicon Carbide Ceramic Ball Bearing
The parameter “HRC ( hardness)” in this context refers to the Hardness range of the ceramic ball bearing you’re referring to. The higher the Hardness rating, the harder the material will be. For example, if it has an HRC value of 90, that means the material will have a hardness level of around 72-84 on the Mohs scale.
A hardness of 90 is considered very high, indicating that the ceramic ball bearing will be extremely hard and durable under high temperatures. This makes it ideal for use in applications where temperature fluctuations can cause wear and tear, such as in industrial machinery or aerospace components.
It’s important to note that the hardness rating does not necessarily indicate how rough the surface of the bearing will be. A high hardness rating also indicates that the bearing will have good shock resistance and long lifespan, but it may not be suitable for low-temperature applications or environments with heavy friction.
Overall, a ceramic ball bearing with an HRC value of 90 will provide excellent performance under high temperatures and rough surfaces, making it a reliable choice for many different types of applications.
