2543052
for CAT
Crafted as a premium OEM replacement pin, the OEM 2543052 excavator bucket pin is specifically engineered to match the performance requirements of the Caterpillar 320 series, including CAT320 GX, CAT320 GC, and standard CAT320 models. As a core excavator pin shaft component, it serves as a reliable alternative to original parts, designed to withstand the extreme pressure, impact, and wear of daily excavation, loading, and unloading operations. Manufactured by ZHUOQUN MACHINERY, a certified enterprise with AAA-level credit and quality management system certification, this heavy-duty steel pin combines high strength, precision, and durability to ensure optimal functionality and extended service life for your Caterpillar equipment. Whether used in construction sites, mining projects, or earth-moving tasks, this bucket pin is a cost-effective solution that balances quality and performance.
Made from top-grade 42CrMo alloy steel, 40Cr steel, or 45# steel—all selected for their exceptional mechanical properties—this excavator bucket pin undergoes a specialized heat treatment process (quenching and tempering) to enhance its strength and wear resistance. The quenching stage (heated to 850℃-880℃) forms a martensite structure, boosting hardness, while subsequent tempering (550℃-650℃) eliminates internal stress and improves toughness. This combination allows the pin to withstand massive loads and frequent impacts without deformation or premature failure, ensuring a long service life even in harsh working conditions.
Employing advanced precision machining technology, the OEM 2543052 bucket pin achieves extremely tight dimensional accuracy. The outer circle size tolerance is controlled within ±0.01mm, and the surface roughness reaches Ra0.8-Ra1.6μm, guaranteeing a perfect fit with other Caterpillar 320 components such as the bucket, connecting rod, and boom. This precise fit minimizes clearance and reduces wear between parts, enhancing the overall stability and reliability of the excavator during operation.
The pin’s surface is either specially treated or designed with integrated lubrication channels that effectively store and distribute lubricating oil. This feature reduces the friction coefficient between the bucket pin and mating parts, lowering energy consumption and improving work efficiency. Adequate lubrication also prevents dry friction, further extending the service life of both the pin and associated components.
When paired with appropriate seals, the OEM 2543052 excavator bucket pin delivers outstanding sealing performance. It prevents lubricating oil leakage and blocks external impurities (such as dust, sand, and moisture) from entering the working area, keeping internal components clean and protected. This sealing capability avoids premature damage caused by contamination, safeguarding the entire excavator system.
Through surface treatments like hard chrome plating (0.02mm-0.05mm thickness) or blackening, the bucket pin gains excellent corrosion resistance. These treatments form a protective film on the surface, enabling the pin to maintain stable performance in harsh environments—including humidity, dust, acid, and alkali. It resists rust and corrosion, ensuring consistent functionality even in long-term outdoor or challenging job site conditions.
The OEM 2543052 bucket pin is primarily used to connect the excavator bucket with critical components such as the connecting rod and boom. It provides stable support and fixation, maintaining accurate relative positions between parts to ensure the bucket moves according to design specifications. This application is essential for all excavator operations, from digging trenches to loading materials.
As a key power-transmitting component, this excavator pin shaft transfers power and torque from the hydraulic cylinder and other power units to the bucket. It enables the bucket to generate sufficient force for heavy-duty tasks like excavating hard soil, breaking rocks, and loading bulk materials. This function is indispensable in construction, mining, and earth-moving projects where high power output is required.
The pin serves as a stable axis for the rotation and swing of the excavator bucket, allowing flexible movement at various angles and directions. This flexibility enables the Caterpillar 320 to adapt to complex working conditions—such as uneven terrain, narrow spaces, and multi-angle excavation—meeting diverse operational needs efficiently.
