Power End Cross Pin

The Power End Cross Pin is a key component that connects the connecting rod to the crosshead, primarily used to transmit power and withstand the lateral forces generated by piston movement.

High-Strength Alloy Steel Material: 42CrMo/20CrNiMo forging, tensile strength ≥1000MPa, no fracture under high impact loads.

Vacuum Heat Treatment Process: Vacuum quenching + tempering, surface hardness HRC58-62, fatigue life extended 3 times.

Full-Dimension Inspection System: CMM + ultrasonic testing 100% inspection, defect rate ≤0.3%.

Standardized Interchangeable Design: Compliant with API 7K standard, directly compatible with Gardner Denver/National mainstream pump models.

Oil Drilling: Used in the power end of mud pumps, connecting the crankshaft and connecting rod, transmitting reciprocating motion power.
Natural Gas Extraction: Paired with fracturing pump equipment, withstanding high-pressure reciprocating shock loads.
Offshore Drilling: Used in the mud pump system of offshore drilling platforms, designed for high humidity and high-salinity environments.
Geological Exploration: Paired with drilling equipment power ends, ensuring stability during continuous operations.
Coalbed Methane Development: Used in coalbed methane drilling mud pumps, transmitting power to drive piston movement.
Shale Oil and Gas Development: Paired with fracturing equipment power ends, withstanding high-frequency alternating loads.
