I. Introduction to carbide bush

A tungsten carbide bushing is a cylindrical device that finds widespread use in mechanical applications for its exceptional wear resistance and toughness. The material of choice for its manufacture is tungsten carbide, which imparts the material with its exceptional strength and durability. Owing to their outstanding characteristics, tungsten carbide bushings often replace conventional materials like steel or ceramic in applications that require  superior performance and durability.

High-precision applications in industries such as aerospace, automotive, and oil and gas commonly employ tungsten carbide bushings. These components demonstrate remarkable resistance to corrosive environments, heavy loads, and high temperatures, all while maintaining a low coefficient of friction, thereby making them ideal for applications that mandate smooth operation and high accuracy.
