Product DescriptionProduct DescriptionForged Steel Connecting Rod / Heavy-Duty Linkage Rod1. 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 FeaturesMaterial: 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.ApplicationsConstruction 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 ServicesDimensions: 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.COO:CHINA
