Key Features & Benefits at a Glance
- Precise 0.2" travel per turn ensures accurate linear positioning for repeatable motion control applications.
- High tensile strength (64,000 psi) Grade 2 carbon steel construction provides reliable load-bearing capacity and resistance to deformation under stress.
- Class 2G thread fit with ACME thread profile offers smoother engagement, reduced wear, and excellent backlash control for long-term performance.
- Rockwell B61 hardness rating enhances durability and wear resistance in demanding industrial environments.
- Fully threaded 3-foot length and right-hand direction allows for versatile installation and consistent force transmission across the entire screw.
- Compliance with ASTM A108, RoHS 3, and REACH standards guarantees material consistency, environmental safety, and global regulatory acceptance.
- Single-start thread design with 1:1 speed ratio simplifies synchronization and provides predictable linear motion for automation systems.
Professional Applications & Engineering Value
This 1 1/4"-5 ACME lead screw is engineered to solve critical challenges in precision motion control systems, such as CNC machinery, linear actuators, and industrial automation. The Grade 2 carbon steel material, combined with ACME threading and Class 2G thread fit, minimizes friction and wear while maintaining positional accuracy under continuous operation. Its 0.2" travel per turn and fully threaded design ensure efficient force conversion and smooth movement, reducing maintenance downtime. Ideal for applications requiring high tensile strength and reliable performance, this lead screw supports heavy-duty lifting, precise positioning, and long-term operational stability in manufacturing and assembly lines.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for consistent engagement and is manufactured in accordance with ASTM A108 specifications. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and material traceability. The inch system measurement, 1 1/4"-5 ACME thread size, and right-hand thread direction are precision-engineered for compatibility with standard industrial components.
