S-99030A457 2"-4 x 3 ft. Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional positioning accuracy with ±0.009" per foot tolerance for reliable, repeatable motion control in automated systems.
• Superior strength and durability from 1018 carbon steel construction, offering a high 64,000 psi tensile strength for demanding industrial applications.
• Optimized for non-standard motion requirements with a left-hand thread direction, providing design flexibility for specific mechanical assemblies.
• Consistent and predictable linear motion due to the single thread start and 0.25" travel per turn of the precision ACME thread form.
• Robust wear resistance with a Brinell 126 hardness, ensuring a long service life and reduced maintenance needs.
• Guaranteed interchangeability and fit through the standardized Class 2C thread fit, facilitating easier assembly and replacement.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This high-precision ACME lead screw is engineered to solve critical challenges in industrial automation and motion control systems. Manufactured from 1018 carbon steel, it provides the necessary tensile strength and hardness to withstand continuous operation in machinery such as CNC tables, linear actuators, and precision positioning equipment. The left-hand thread is essential for applications requiring reverse-direction movement or specific mechanical advantage, while the fully threaded 3-foot length offers maximum utility in long-travel systems. The ACME thread type and Class 2C fit ensure smooth, low-friction operation with minimal backlash, making it an ideal motion control component for engineers seeking reliability and accuracy in demanding environments.

Specification Summary & Compliance

This component features a 2"-4 ACME thread with a Class 2C thread fit and a single thread start, delivering a consistent 0.25" travel distance per turn. It is manufactured to precise dimensional standards, including the critical travel accuracy of ±0.009" per foot. The lead screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial use.
