This POM shaft core bar is CNC-machined from high-quality POM engineering plastic. The material inherently features a low coefficient of friction, excellent rigidity, and creep resistance, along with self-lubricating properties, making it suitable for oil-free sliding and light-load reciprocating transmission applications. The product retains its original machined surface, requiring no additional surface treatment. The material is stable and resistant to rust, effectively reducing equipment operating noise. We support flexible OEM customization and can adjust the bar length, outer diameter, flange dimensions, and mounting hole positions according to customer drawings to meet the assembly requirements of various automation equipment and tooling fixtures. As a reliable OEM shaft core bar, it features strict dimensional tolerance control, smooth sliding, and wear resistance, making it the preferred lightweight alternative to metal shaft components.
