• Exceptional positioning accuracy of ±0.005" per foot ensures repeatable precision in demanding CNC and linear motion applications.
• High load capacity and durability from a 150,000 psi tensile strength and Rockwell C38 hardness, providing reliable performance under heavy loads.
• Wide operational temperature range from -65°F to 300°F ensures stable performance in both extreme cold and high-heat settings.
• Optimized for smooth, efficient motion through rolled thread fabrication and a ball thread type, reducing friction and wear for long service life.
• Compliance with environmental standards via RoHS 3, making it suitable for global markets and eco-conscious manufacturing processes.

Professional Applications & Engineering Value

This 3/4"-4 ball screw is engineered to solve critical challenges in precision linear motion systems. Manufactured from 17-4 PH Stainless Steel, it provides excellent corrosion resistance, which is vital for machinery operating in humid, chemically exposed, or washdown environments, preventing premature failure. The fully threaded design with a 0.5" travel per turn and 2 thread starts enables rapid traverse rates, making it ideal for fast-travel applications in CNC machining centers, automated assembly lines, and high-speed gantry systems. The rolled thread fabrication enhances surface integrity and fatigue life, while the tight ±0.005" per foot accuracy ensures precise positioning, reducing scrap rates and improving overall equipment effectiveness in precision machinery.

Specification Summary & Compliance

This ball screw features a 3/4"-4 thread size with a 0.63" root diameter, right-hand thread direction, and is fully threaded over its 6 ft. length. It meets typical precision engineering tolerances for travel distance accuracy. The component is manufactured in compliance with RoHS 3 (2015/863/EU), ensuring it is free from hazardous substances, and is suitable for use in regulated industries requiring adherence to environmental and safety standards.
