Professional Applications & Engineering Value

This acetal plastic flange nut addresses critical challenges in fast-travel ultra-precision lead screw systems where speed, accuracy, and durability intersect. The rounded Acme thread profile significantly reduces friction compared to standard Acme threads, minimizing wear and extending service life in high-cycle applications. The 4:1 speed ratio enables rapid linear movement while maintaining precise control, making it ideal for automated positioning systems, medical devices, and precision manufacturing equipment. The acetal plastic material provides excellent dimensional stability and natural lubricity, eliminating the need for additional lubricants in cleanroom or food processing environments. With three mounting holes integrated into the flange design, installation time is reduced while ensuring secure attachment in motion control assemblies.

Specification Summary & Compliance

This precision component features 1/2"-8 rounded Acme threading with right-hand direction and four thread starts, delivering 0.5" travel per revolution. The flange configuration includes a 1-1/2" diameter with 1-1/8" bolt circle and three 13/64" mounting holes for secure attachment. Manufactured to exacting standards, this nut provides 150 lbs dynamic thrust capacity and 9700 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in global industrial applications.
