Pivot Pin

Selected materials such as 45#, 40Cr, and 42CrMo as the primary materials, which can also be customized according to customer requirements. Through advanced heat treatment processes, the surface hardness can reach HRC 58-62, offering excellent toughness, yield resistance, and tensile performance. The tensile strength can reach σb(MPa): ≥1080 (110), and the yield strength σs(MPa): ≥930 (95).

Quenched and tempered + surface hardening, providing strong toughness, high hardness, and resistance to bending and wear.

High-precision coaxiality ensures smooth assembly without jamming or eccentric wear.

Multiple specifications compatible with various machine models' boom/arm/bucket.

Anti-loosening structure for secure installation.

Custom sizes and surface treatments supported.
