Top-Quality Long Axis Components for Heavy-Duty CNC Milling: This 420J2 Stainless Steel Long Shaft with Side Holes and Threads is a precision-engineered part for power transmission, actuation, or positioning systems. Made from 420J2 stainless steel, it offers exceptional hardness and wear resistance after heat treatment. Key features—long shaft geometry, side holes for lubrication, pinning, or sensing, and machined threads for mounting or adjustment—are achieved through advanced CNC milling. This ensures concentricity, positional accuracy, and durability for high-load applications in industrial, automotive, and specialized machinery.
