Product Description

Product Description

Forged Steel Connecting Rod / Heavy-Duty Linkage Rod
1. Product Overview Our Forged Steel Connecting Rod is a critical mechanical component designed for transmitting motion and force in industrial machinery, construction equipment, and agricultural vehicles. Manufactured through precision forging from high-quality carbon steel (45#/50#) or alloy steel (40Cr), this rod features exceptional tensile strength, impact resistance, and durability. The product is characterized by two end holes for pivot connection, a reinforced middle section, and a black oxide or zinc-plated surface for corrosion protection. Suitable for heavy-load scenarios, it serves as a key linkage part in engines, pumps, cranes, and mechanical transmissions.
2. Key Features
Material: Carbon steel (45#/50#) or alloy steel (40Cr), forged at 1000-1200℃ for grain refinement.
Mechanical Properties: Tensile strength ≥600MPa, yield strength ≥355MPa, hardness HB187-255.
Precision Forging: One-piece forging process ensures uniform density and no internal cracks.
Surface Treatment: Black oxide (for corrosion resistance in dry environments) or zinc plating (for humid/indoor use).
Dimensional Accuracy: Hole diameter tolerance ±0.05mm, length tolerance ±0.1mm (CNC machined after forging).
Load Capacity: 5-50kN (varies by size; custom design for higher loads available).
3.Applications
Construction Machinery: Linkage in excavators, loaders, cranes, and concrete mixers.
Agricultural Equipment: Transmission parts in tractors, harvesters, and tillers.
Industrial Machinery: Pumps, compressors, conveyors, and mechanical presses.
Automotive & Engines: General-purpose connecting rods for diesel/gasoline engines (non-high-performance).
Marine & Mining: Heavy-duty linkage in ship winches and mining machinery.
4.Customization Services
Dimensions: Length, hole diameter, thickness, and shape can be customized per 2D/3D drawings.
Material: Carbon steel, alloy steel, or stainless steel (304/316) for special environments.
Surface Treatment: Powder coating, electrophoresis, or galvanization (hot-dip/electrogalvanizing).
Marking: Laser engraving of part numbers, logos, or specifications.
