Description
Ceramic balls are manufactured from advanced materials such as Alumina Oxide, Zirconia Oxide, or Silicon Nitride. These materials offer significant advantages over traditional steel balls. They are 40% lighter, have a 29% lower thermal expansion coefficient (which helps maintain shape under temperature changes), and are 150% harder. This makes them ideal for high-speed, high-performance applications where durability and efficiency are critical.
Benefits
Ceramic balls are known for their lightweight design, high hardness, and excellent toughness. Their low mass reduces energy loss in motion, making them highly efficient in high-speed bearings, such as those found in machine tool spindles and vacuum pumps. Due to their extreme hardness, they generate less friction, allowing more energy to be converted into useful work. In some cases, ceramic balls can last up to 100 times longer than steel balls in high-speed applications. Additionally, they are chemically inert, providing exceptional resistance to corrosion in various environments.
Applications
These ceramic balls are widely used across multiple industries, including automotive and aerospace, where their durability and light weight make them perfect for applications like aircraft braking systems. They are also commonly found in everyday products that previously relied on metal balls, such as aerosol cans, joints, slides (like car seats and safety restraints), castors, ball transfer units, quick disconnect couplings, and various types of fasteners. Their versatility and performance make them a preferred choice in demanding mechanical systems.
