Professional Applications & Engineering Value
This left-hand Acme thread bronze nut delivers critical performance in industrial settings where reverse-motion mechanisms and heavy loads are paramount. The 932 Bearing Bronze material provides natural lubricity and corrosion resistance, reducing maintenance frequency in CNC equipment, lifting systems, and precision actuators. Engineers specify this component for applications requiring counter-clockwise motion transmission while maintaining 2000 lbs dynamic thrust capacity. The Class 2C thread fit ensures smooth operation with standard Acme lead screws, minimizing vibration and wear in continuous operation environments. Its 0.125" travel per turn offers predictable linear motion for positioning tables, clamping devices, and material handling equipment.
Specification Summary & Compliance
Manufactured to inch system standards with 5/8-8 left-hand Acme threads and Class 2C fit tolerance for reliable screw engagement. The component features single-start threading with 1:1 speed ratio and meets industry standards for precision Acme lead screw applications. Material certification includes Brinell 65 hardness verification, ensuring consistent performance under 2000 lbs dynamic thrust loads. Complies with RoHS and REACH environmental directives for industrial components.
