Professional Applications & Engineering Value

This ACME flange nut in 932 Bearing Bronze addresses critical engineering challenges in linear motion systems, where durability and precision are paramount. The bronze material naturally resists galling and wear, reducing maintenance frequency in high-cycle equipment like CNC machines, presses, and lifting mechanisms. With its Class 2G thread fit and right-hand ACME threads, it ensures smooth, predictable movement without jamming, even under continuous operation. The integrated flange simplifies assembly by providing a stable mounting surface, ideal for applications requiring precise alignment and thrust load management. This component is engineered to enhance the reliability of lead screw assemblies in industrial automation, packaging machinery, and material handling systems where consistent performance is non-negotiable.

Specification Summary & Compliance

This ACME flange nut adheres to Class 2G thread fit standards for consistent engagement and minimal backlash. It features a 1 1/2"-4 ACME thread with right-hand direction and a travel distance of 0.25" per turn, ensuring precise linear motion control. The nut is manufactured from 932 Bearing Bronze, known for its self-lubricating properties and compliance with industrial material specifications. Dimensions include a 3 1/2" flange diameter and 3/4" flange thickness for robust mounting. While thrust load capacity and hardness are not rated, the design aligns with common engineering requirements for lead screw accessories in machinery and automation systems.
