S-95072A224 1"-6 x 1 1/2" Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior wear resistance and durability thanks to 673 Bronze construction with Brinell 70 hardness, ensuring extended service life in demanding applications
• Precise and reliable linear motion control with a consistent 0.167" travel distance per turn, providing predictable and accurate positioning
• Optimized for non-standard and safety-critical assemblies featuring a left-hand thread direction to prevent unintended loosening in rotating systems
• Guaranteed interchangeability and smooth operation with a Class 2C thread fit on the 1"-6 Acme internal thread, ensuring minimal backlash
• Enhanced mounting and integration flexibility with an externally threaded 1 3/8"-16 UNS design, allowing for secure attachment to various components
• Compliance with stringent environmental regulations as it is RoHS 3 compliant, making it suitable for regulated industries and global supply chains
• Robust construction for high-load scenarios from the Acme thread form, which is engineered to handle significant axial forces efficiently

Professional Applications & Engineering Value

This precision Acme nut is engineered from 673 Bronze, a material chosen for its excellent anti-galling properties and corrosion resistance, which directly addresses common failure points in linear motion systems. The left-hand Acme thread is critical for applications where reverse-threading prevents accidental disengagement, such as in presses, clamping devices, and machinery where right-hand rotation is standard. With a Class 2C thread fit, it offers a slightly looser fit than Class 3C, facilitating easier assembly and reducing the risk of binding in environments with thermal expansion or contamination. The external 1 3/8"-16 UNS thread allows for straightforward integration into housings or other components, streamlining the design of complex mechanical assemblies. Its 0.167" travel per turn provides a balanced mix of speed and precision, making it ideal for manual adjustments or slower, high-torque automated systems in industrial automation, valve controls, and heavy-duty positioning equipment.

Specification Summary & Compliance

This externally threaded nut adheres to Acme thread standards with a size of 1"-6 and a Class 2C thread fit, ensuring dimensional accuracy for reliable performance. The external thread follows the UNS standard at 1 3/8"-16. It is manufactured from 673 Bronze and meets RoHS 3 (2015/863/EU) compliance under exemption 6(c) for lead in copper alloys, confirming its suitability for use in regulated environments without sacrificing material integrity.
