S-95120A555 1"-6 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Enhanced Durability & Wear Resistance: Crafted from 932 Bearing Bronze, this nut offers superior corrosion resistance and long service life in demanding environments.
• Precision Linear Motion: Provides a consistent 0.167" travel per turn, ensuring accurate and repeatable positioning in automated systems.
• Secure Flange Mounting: The integral 2-1/2" diameter flange with a 1/2" thickness offers a stable, bolt-down mounting solution, resisting rotation and loosening under load.
• Reliable Left-Hand Threading: The 1"-6 left-hand Acme thread is ideal for applications requiring reverse motion or specialized assembly configurations.
• Optimized Thread Fit: The Class 2G thread fit ensures smooth engagement with the lead screw, reducing backlash and providing consistent performance.
• Robust Construction: The one-piece 932 Bearing Bronze construction for both the nut and flange ensures compatibility and strength for heavy-duty industrial use.
• Versatile Integration: Designed as a direct replacement or upgrade component for linear motion systems requiring a reliable, self-lubricating bronze nut.

Professional Applications & Engineering Value

This Left Hand Acme Flange Nut is engineered to solve critical challenges in industrial linear motion systems. The use of 932 Bearing Bronze provides natural lubricity, reducing friction and wear on the mating Acme lead screw without the constant need for external lubricants, which is vital in dirty or food-processing environments. The left-hand thread is essential for complex mechanical assemblies where reverse motion synchronization is required, such as in opening/closing mechanisms or custom machinery. The large flange diameter and substantial thickness distribute clamping force evenly, preventing misalignment and absorbing thrust loads effectively. This combination of material and design ensures reliable performance in CNC equipment, valve actuators, and heavy-duty lifting systems, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This flange nut adheres to standard Acme thread specifications with a Class 2G thread fit, providing a free-running assembly with commercial tolerance for smooth operation. The thread size is 1"-6 left hand. The component is manufactured from 932 Bearing Bronze, a leaded tin bronze alloy known for its machining and bearing properties. It is compliant with industry-standard material specifications and is suitable for use in systems requiring RoHS and REACH environmental compliance.
