Mingxing's ceramic bushing and ceramic piston components are engineered for high durability and reliability. Our complete manufacturing process control, from forming to finishing, allows us to maintain the highest standards for your custom components.

Ceramic Bushing

Ceramic Bushing, also known as eyelet or ferrule, exhibits excellent dielectric and thermal properties, making them ideal for use as electrical bushings and in high-temperature applications. Alumina ceramics and SiC Ceramics offers outstanding durability. Ceramic Bushing is commonly used as antenna insulators, to support wires, rods or grids in ovens, and as wire guides in high voltage electrical equipment, among other uses.

As top 5 ceramic bushing suppliers, Mingxing ceramics‘ technical ceramics business offers a comprehensive line of Ceramic Bushing for use in a range of power generation and distribution applications. Engineered to some of the industry’s highest tolerances, our Ceramic Bushing provides unrivaled reliability, quality, and performance within high wear environments.

Ceramic Piston

Ceramic Piston inherits the hard and wearable nature of their ceramic parent material, making them more durable. The relatively low density of alumina ceramics or SiC ceramics also makes it lighter and easier to manage, repair, and maintain than metal-coated plungers. Ceramics have a lower coefficient of friction, resulting in less sliding resistance of the piston and reduced wear of Ceramic Piston during prolonged operation.

Mingxing ceramics‘ Ceramic Piston is manufactured from alumina ceramics or SiC ceramics. Among the primary benefits of Ceramic Piston is their resistance to salt water, oil, and some chemical solutions. This characteristic makes Ceramic Piston ideal for the medical, food and beverage, petrochemical, and specialty chemical industries where there are tight regulations regarding fluid contamination.
