S-93026A657 1 1/4"-5 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Reliable reverse-thread engagement with left-hand Acme threading for applications requiring counter-clockwise tightening or specific mechanical movements.
• Durable carbon steel construction with Rockwell B75 hardness ensures excellent wear resistance and longevity in demanding industrial environments.
• Precise Class 2G thread fit provides consistent, smooth engagement with mating components, reducing backlash and improving operational accuracy.
• Efficient 0.2" travel per turn delivers predictable linear motion control, ideal for precise positioning in lead screw assemblies.
• Versatile coupling nut design enables secure connection of two externally threaded rods, simplifying assembly and maintenance.
• Standard inch system compatibility ensures easy integration with existing North American machinery and replacement parts.
• Robust 3" height and 1 5/8" width provide ample gripping surface for secure installation and handling during operation.

Professional Applications & Engineering Value

This left-hand Acme coupling nut is engineered to address specific industrial needs where reverse-thread mechanisms are critical. The carbon steel material, combined with Rockwell B75 hardness, offers superior resistance to deformation and wear in high-cycle applications such as linear actuators, clamping systems, and precision machinery. The Class 2G thread fit ensures minimal play and reliable performance in assemblies requiring accurate motion transfer. Its 1 1/4"-5 Acme thread and 0.2" travel per turn make it ideal for applications demanding controlled linear displacement, such as in packaging equipment, CNC adjustments, and material handling systems where reverse threading prevents unintended loosening from vibrational forces.

Specification Summary & Compliance

This component features a 1 1/4"-5 left-hand Acme thread with Class 2G fit per standard inch system requirements, ensuring dimensional accuracy and interchangeability. Manufactured from carbon steel with a specified hardness of Rockwell B75, it adheres to common industrial standards for mechanical components. The nut is designed for general industrial use and complies with typical material and manufacturing specifications, though specific ratings like thrust load capacity are not provided. It is suitable for applications requiring standard inch system components without specialized certifications.
