Precision Ceramic balls
lightweight precision and durability
When lightweight strength and durability are required, ceramic balls are the answer. They are found in high-speed bearings for spindle motors, turbochargers, and dental drills; metering pumps used in water treatment and food processing; EVs that demand lightweight performance, including valve balls in fuel injection systems; and power generation and semiconductor equipment. Our ceramic balls deliver superior wear, heat, and corrosion resistance, making them ideal for demanding applications where durability, reliability, and high-speed performance are critical.

product information
Tsubaki Nakashima Precision Ceramic Balls provide industries with accuracy, durability, and efficiency, making us a go-to global supplier. These advanced fine ceramics weigh less than half as much as steel yet deliver even greater strength, so they perform well in tough conditions without sacrificing reliability. They also resist wear, corrosion, and high temperatures, making them a top choice when steel balls fall short.
We produce ceramic balls in four main material types, each designed to meet specific performance needs.
We accept orders for non-standard dimensions and specifications upon request.
