• Precise linear motion control with a 0.125" travel distance per turn and rounded Acme thread for smooth, accurate positioning
• Reliable dynamic load handling with a 25 lbs thrust capacity and 9700 psi tensile strength for consistent performance
• Simplified installation and secure mounting via the integrated flange with 3 pre-drilled holes and a 1-1/4" bolt circle
• Environmental regulation compliance with RoHS 3 and REACH standards, ensuring safe use in regulated markets
• Optimized for ultra-precision systems with a 1:1 speed ratio and right-hand thread for direct, efficient power transmission

Professional Applications & Engineering Value

This 1/2-8 Acetal Plastic Flange Nut is engineered to address common challenges in ultra-precision lead screw applications, such as backlash and wear-induced inaccuracies. The wear-compensating spring technology maintains constant contact with the screw threads, effectively minimizing play and ensuring long-term positional accuracy in CNC machinery, medical devices, and optical positioning systems. Made from durable Acetal Plastic, it offers low friction and resistance to moisture and chemicals, reducing the need for lubrication and preventing contamination in cleanroom or laboratory settings. The rounded Acme thread form and right-hand thread direction provide smooth, efficient motion transfer, while the flange design with multiple mounting holes simplifies integration and enhances stability in high-precision assemblies.

Specification Summary & Compliance

This flange nut features a 1/2"-8 rounded Acme thread with standard right-hand direction and a 1:1 speed ratio for precise linear actuation. Key dimensional attributes include a 2" length, 0.891" diameter, and flange details of 1-39/64" diameter and 17/64" thickness, with a bolt circle diameter of 1-1/4" and three 13/64" mounting holes. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
