Precision Finish Solid Rod

The precision finish solid rod is manufactured from high-quality alloy steels and stainless steels, including 45# steel, 40Cr, 42CrMo, and stainless steel. These materials provide an excellent balance of strength, toughness, and structural stability, making the rod suitable for demanding industrial applications.

With advanced machining processes and strict quality control, the rod achieves an accuracy range of F5 to F9, ensuring consistent dimensional precision and superior surface finish. The available diameter range from Φ20 to Φ500 allows flexible selection for various mechanical and hydraulic systems.

A hard chrome plating layer can be applied to the surface, with thickness ranging from 0.010mm to 0.10mm. This treatment significantly enhances wear resistance, corrosion resistance, and surface hardness, ensuring reliable performance under high load and continuous operation conditions.

Precision finish solid rods can also be machined according to customer drawings, enabling customized dimensions and tolerances. This flexibility ensures excellent compatibility with hydraulic cylinders, mechanical transmission systems, and automated equipment, contributing to stable operation and long service life.
