Ultra-Precision 0.001mm Straightness Custom Made Tungsten Carbide Piston Rod with 0.001 - 0.01 mm Precision

Product Overview

The Tungsten Carbide Piston Rod is a core motion component specifically engineered for ultra-precision applications. Manufactured from micro-grain tungsten carbide through isostatic pressing and multi-stage precision grinding, it achieves an exceptional straightness of ±0.001mm. This ensures zero-deviation operation during high-speed reciprocating motion, making it ideal for demanding fields such as semiconductor dispensing equipment, precision metering pumps, and aerospace actuators.
