S-98980A103 3/4"-5 x 6 ft. Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 304 Stainless Steel construction, ideal for harsh industrial environments.
• Exceptional positional accuracy with a travel distance tolerance of ±0.009" per foot for reliable, repeatable linear motion.
• High mechanical strength and durability from a 72,000 psi tensile strength and Brinell 150 hardness to withstand heavy loads.
• Optimized for non-reversing applications with a left-hand Acme thread design, preventing unintended loosening.
• Consistent and smooth power transmission due to a single-start, fully threaded design with a 1:1 speed ratio.
• Guaranteed interchangeability and fit with Class 2C thread fit, ensuring compatibility with standard Acme nuts.
• Environmentally compliant manufacturing meeting RoHS 3 standards for use in regulated industries.

Professional Applications & Engineering Value

This precision Acme lead screw is engineered to solve critical challenges in linear motion systems where reliability and accuracy are paramount. The use of 304 Stainless Steel provides excellent corrosion resistance, making it suitable for food processing, medical equipment, and outdoor machinery. The left-hand Acme threading is specifically designed for applications requiring a counter-directional drive, preventing accidental back-driving in lifting mechanisms or clamping devices. With a tight travel accuracy of ±0.009" per foot and a single-start, fully threaded design, it delivers predictable and precise movement, reducing system wear and maintenance needs. This component is ideal for high-precision CNC stages, valve actuators, and automated positioning systems where consistent performance under load is essential.

Specification Summary & Compliance

This lead screw adheres to inch system measurements with a 3/4"-5 Acme thread size and Class 2C thread fit for standardized compatibility. It features a travel distance per turn of 0.2" and is manufactured to meet precise dimensional tolerances. The component is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances, and is produced in accordance with industry-standard mechanical specifications for Acme threaded components.
