Key Features & Benefits at a Glance
- Exceptional positioning accuracy with ±0.009" per foot tolerance for reliable, repeatable linear motion control.
- Superior durability and wear resistance provided by 1018 Carbon Steel construction with a Brinell hardness of 126.
- High mechanical strength with a 64,000 psi tensile strength to withstand significant loads in demanding applications.
- Optimized for reverse or counter-rotational motion with its left-hand ACME thread, preventing unintended loosening.
- Consistent and predictable linear travel of 0.125 inches per revolution for precise speed and positioning.
- Broad compatibility and easy assembly ensured by the Class 2C thread fit, suitable for a wide range of nut assemblies.
- Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental standards.
Professional Applications & Engineering Value
This precision ACME lead screw is engineered to solve critical challenges in industrial automation, CNC machinery, and precision lifting systems. The 1018 Carbon Steel construction offers an optimal balance of strength and machinability, resisting deformation under continuous operation. The left-hand thread direction is specifically designed for applications requiring reverse-threading mechanisms or where standard right-hand threads could unscrew under specific directional forces. With a travel distance of 0.125" per turn and a Class 2C thread fit, it provides the backlash control and positional accuracy needed for sensitive equipment, reducing maintenance cycles and improving overall system reliability. Its fully threaded, 6-foot length offers design flexibility for various mechanical setups.
Specification Summary & Compliance
This lead screw adheres to inch system measurements with a 5/8"-8 ACME thread and a Class 2C thread fit for general purpose use with clearance. It features a single start thread and a 1:1 speed ratio. The component is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent international standards for hazardous substance restrictions.
