Gudgeon Pin
The gudgeon pin, also known as the wrist pin, is a key mechanical component that connects the piston to the connecting rod in a mud pump. It serves as the pivot point that allows the piston to move linearly while the connecting rod rotates with the crankshaft. This pin endures high levels of pressure, heat, and cyclical stress during drilling operations.
Manufactured from high-strength alloy steel and precision-ground for tight tolerances, gudgeon pins are engineered to resist fatigue, deformation, and wear even under continuous high-load conditions. Their role is critical to the performance and mechanical integrity of the pump’s power end.
All gudgeon pins in this category are fully compatible with mud pumps from FMC BEAN, ATLAS COPCO (Trido series), and TRIAQUA, ensuring secure fit, smooth motion, and long-term reliability. They are ideal for pump overhauls, maintenance, or direct replacement of worn wrist pins.
