High Precision Carbon Steel Connecting Rod Pin Non-Standard Linkage Shaft Pin for Mechanical Applications
Situo Hardware is a professional original manufacturer specializing in carbon steel connecting rod pins, mechanical linkage shaft pins, non-standard articulated locating pins and industrial transmission connecting pin parts. Our products are widely used in general mechanical equipment, automatic transmission mechanisms, link hinge assemblies, tooling linkage equipment, heavy-duty mechanical connections and hardware transmission accessories.
This series of carbon steel connecting rod pins is made of high-quality carbon structural steel, formed by composite technology of precision machining and cold heading finishing. It features high overall hardness, excellent wear resistance and shear resistance, specially designed for mechanical link transmission, hinge movement and positioning & fixing working conditions.
Made of national standard high-quality carbon steel with uniform density and balanced toughness and hardness. Excellent shear resistance, impact resistance and compression resistance suitable for heavy-duty machinery and high-frequency transmission.
Cold heading forming + precision finishing process ensures complete metal structure. Strict control of outer diameter tolerance, straightness and coaxiality with smooth burr-free surfaces.
Integral solid design without splicing and welding features superior structural strength. Can bear high torque, high frequency and heavy-load transmission operations with long service life.
Customizable specifications include pin outer diameter, total length, positioning step, limit slot, end chamfer, slotting, flat milling, drilling and tapping. Support for special-shaped structures and diverse non-standard requirements.
Multiple surface treatments available: natural precision grinding, galvanizing, nickel plating, blackening quenching and tempering hardening. Anti-rust treatments prevent carbon steel oxidation for various working environments.
Standardized full-process quality control includes raw material inspection, dimensional tolerance detection, coaxiality & straightness sampling, surface hardness testing and burr trimming for stable batch consistency.
