Description
M12 Ball Head Upper Pressure Rod designed for automotive steering systems and precision measuring instruments, providing stable transmission and accurate force control. The ball head and hexagon structure are formed through a one-step cold heading process, ensuring high dimensional accuracy, excellent strength, and consistent quality without secondary machining.
Manufactured from 40Cr alloy steel (AISI 4140 / JIS SCM440 equivalent), this M12 Ball Head Upper Pressure Rod offers superior toughness, wear resistance, and long service life under dynamic loading conditions. With an overall dimension of φ33.5 × 73.5 mm and precise structural features including SR16 mm ball head and SW22 -0.2 mm hexagon with R0.8 mm detailing, it ensures reliable assembly, smooth operation, and precise performance in steering and measurement applications.
