Professional Applications & Engineering Value

This 303 Stainless Steel flange is engineered to address critical challenges in precision lead screw systems, where corrosion, misalignment, and component failure can disrupt operations. Its UN thread form (15/16"-16) ensures precise mating with lead screw nuts, minimizing backlash and enhancing motion control accuracy. The Brinell 140 hardness and sturdy 2 5/8" diameter provide excellent load-bearing capacity, reducing deformation in high-stress applications like CNC machinery, automation equipment, and linear actuators. By incorporating four mounting holes and a corrosion-resistant finish, it offers reliable performance in environments exposed to moisture, chemicals, or temperature variations, ultimately extending service life and reducing maintenance costs for industrial users.

Specification Summary & Compliance

This flange adheres to UN thread standards with precise dimensional tolerances, including a flange diameter of 2 5/8", thickness of 17/32", and bolt circle diameter of 2 3/32". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for use in regulated industrial and international markets.
