4043000173 Pin Shaft

High-precision 4043000173 pin shaft for heavy-duty construction machinery and truck equipment. OEM standard mechanical pin shaft, factory wholesale, flexible MOQ, fast delivery and complete certifications for global aftermarket replacement.

The 4043000173 pin shaft is a core mechanical connecting and bearing component widely applied to construction machinery and heavy truck equipment. It serves as a key assembly part for mechanical linkage, rotation connection and load bearing, ensuring flexible movement and stable structural cooperation between mechanical components. This pin shaft adopts high-strength alloy steel raw materials and undergoes overall quenching and tempering heat treatment, featuring high surface hardness, strong compression resistance and excellent shear resistance. Precision CNC machining ensures smooth surface and accurate dimensional tolerance, achieving tight assembly gap and stable operation. It effectively avoids mechanical jitter, component deviation and structural abrasion under long-term heavy-load and high-frequency working conditions. Manufactured strictly in accordance with OEM technical and dimensional standards, the 4043000173 pin shaft supports 100% direct interchangeability, perfectly suitable for equipment maintenance and parts replacement.
