Drive Connecting Rod

Our Drive Connecting Rod is a precision-engineered mechanical linkage component, designed for reliable power transmission and motion control in industrial machinery and building material equipment.

Core Technical Specifications

1. Material & Heat Treatment

• Material: 40Cr alloy steel, offering high tensile strength, excellent toughness, and superior fatigue resistance, ideal for repeated cyclic loading in drive systems.

• Quenched & Tempered Treatment: Heat treated to achieve 300–350 HBS hardness, ensuring optimal mechanical performance and wear resistance under continuous operation.

• Surface Treatment: Decorative chrome plating provides enhanced corrosion resistance and a smooth, durable finish, while improving wear resistance for long-term service life.

2. Precision Machining & Design

• Tight Tolerance Compliance: Unmarked dimensions follow GB/T 1804-m (medium tolerance grade), ensuring consistent fit and alignment across all critical features.

• Precision Bore Machining: Multiple precision bores (Ø20 H7, Ø34 H7, Ø25 H7) with tight positional tolerances (φ0.020mm relative to datum A) guarantee precise concentricity and alignment with mating shafts, pins, and bearings.

• Edge Finishing: All sharp edges are deburred and chamfered to C0.5mm, eliminating stress concentrations and ensuring safe handling during assembly.

• Paired Machining: Manufactured as left/right mirror-image pairs and clearly marked, ensuring consistent performance and interchangeability within the drive linkage system.

3. Structural & Functional Features

• Optimized Linkage Geometry: The contoured, multi-hole design efficiently transmits rotational motion into linear or oscillating movement, suitable for heavy-duty drive systems.

• High Fatigue Resistance: The 40Cr material and robust geometry resist fatigue failure under repeated loading, ensuring reliable operation in 24/7 industrial production environments.

• Corrosion & Wear Resistance: The chrome-plated surface protects against rust and abrasion, extending service life in dusty, humid workshop conditions.

Key Applications

• Industrial building material machinery (e.g., forming, cutting, and conveying drive systems)

• Mechanical linkage and power transmission assemblies

• Automation equipment and heavy-duty drive systems

• Industrial machinery requiring precise, repeatable motion control
