Product Description

Ultra-Precision 0.001mm Straightness The Tungsten Carbide Piston Rod
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.
Core Performance Advantages
Nanoscale Straightness Accuracy
  • Full-stroke straightness ≤ 0.001mm
  • Radial runout tolerance ≤ 0.0005mm
