Product Description

Product Description

Forged Steel Connecting Rod / Heavy-Duty Linkage Rod

1. The Mechanical Connecting Rod is a critical component in industrial machinery, automotive systems, and agricultural equipment, designed to transmit motion and force between rotating or reciprocating parts (e.g., engine crankshafts, conveyor belts, and farm machinery linkages). Crafted from high-strength Q235 carbon steel and manufactured via hot forging, this rod offers exceptional durability, wear resistance, and load-bearing capacity—making it ideal for heavy-duty applications.

With an overall length of 300mm and end holes of 10mm/12mm, the rod is compatible with standard bolts and shafts, ensuring easy integration into existing systems. The black oxide coating provides corrosion resistance, extending its service life in damp or dusty environments (common in factories, farms, and construction sites).

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.
