S-98980A242 3/4"-5 x 3 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 and extending service life.
• Exceptional travel accuracy of ±0.009" per foot ensures highly predictable and repeatable linear motion for precision applications.
• High tensile strength of 72,000 psi provides reliable load-bearing capacity and resistance to stretching or breaking under stress.
• Optimized for left-hand thread applications, offering design flexibility for assemblies requiring reverse-direction linear movement.
• Consistent performance with a Class 2C thread fit, facilitating smooth engagement with matching nuts and reducing backlash.
• Durable wear resistance from a Brinell 150 hardness rating, maintaining thread integrity over extended cycles.
• Environmental compliance with RoHS 3 standards, ensuring the lead screw is free from hazardous substances for safe use.

Professional Applications & Engineering Value

This 3/4"-5 Left Hand Acme Lead Screw is engineered to solve critical challenges in precision linear motion systems. Manufactured from 304 Stainless Steel, it resists corrosion in demanding settings like food processing, packaging, and outdoor machinery, reducing maintenance downtime. The Acme thread profile and fully threaded design deliver high efficiency and load distribution, while the left-hand thread direction is essential for specialized equipment requiring counter-rotational movement. With a precise travel distance of 0.2" per turn and tight accuracy tolerances, it ensures repeatable positioning in CNC tables, actuators, and clamping systems, minimizing errors and enhancing operational reliability for B2B industrial users.

Specification Summary & Compliance

This lead screw adheres to inch system dimensions with a 3/4"-5 thread size and Class 2C thread fit for standardized compatibility. It features a single thread start and 1:1 speed ratio for straightforward motion control. The product conforms to RoHS 3 (2015/863/EU) regulations, ensuring environmental safety, and is backed by a Brinell 150 hardness and 72,000 psi tensile strength for consistent performance under mechanical stress.
