Excavator Pin Shaft
Product Features
High strength and durability: Made of high-quality steel, it has undergone a special heat treatment process and has high strength and excellent wear resistance. It can withstand the huge pressure and impact generated by the excavator during excavation, loading and unloading operations, and has a long service life.
High-precision dimensions: Precision machining technology is used in the production process to ensure that the bucket pin has extremely high dimensional accuracy, and can accurately match other parts of the Caterpillar 320 excavator to reduce clearance and wear, and ensure the stability and reliability of the excavator.
Good lubrication performance: The surface of the bucket pin may be specially treated or designed with lubrication channels, which can effectively store and transmit lubricating oil, reduce the friction coefficient with other parts, reduce wear, improve work efficiency, and also help reduce energy consumption.
Reliable sealing performance: When used with seals, it can effectively prevent lubricating oil leakage and external impurities from entering, keep the working environment clean, avoid component damage caused by impurities intrusion, and extend the service life of the entire system.
Corrosion resistance: Through surface treatment processes such as hard chrome plating and blackening, the bucket pin has good corrosion resistance, can maintain stable performance in harsh working environments such as humidity, dust, acid and alkali, and is not easy to rust and corrode.
Product use
Connection and support: It is mainly used to connect the bucket of the excavator with the connecting rod, boom and other components, play a supporting and fixing role, ensure the relative position between the components is accurate, so that the bucket can move according to the design requirements.
Transmit power and torque: When the excavator is working, the bucket pin can transmit the power and torque from the hydraulic cylinder and other power components to the bucket, so that the bucket can generate enough power for excavation, loading and other operations. It is one of the key components to realize the working function of the excavator.
Ensure movement flexibility: Provide a stable axis for the rotation and swing of the bucket, so that the bucket can move flexibly at different angles and directions, and meet the operation needs of the excavator under various complex working conditions.

Product material
High-quality alloy steel: usually 40Cr, 42CrMo and other high-quality alloy structural steels are selected. 40Cr steel has good comprehensive mechanical properties. After quenching and tempering, it can obtain higher strength and toughness; 42CrMo steel has higher strength and hardenability, better fatigue resistance and wear resistance, and is suitable for manufacturing parts that withstand high loads and high impacts, such as excavator bucket pins.
Surface treatment materials: In order to improve the surface properties of bucket pins, some surface treatment materials will be used. For example, chromate used in chrome plating can form a hard and smooth chrome plating layer on the surface of the bucket pin, improving wear resistance and corrosion resistance; alkaline oxidizing liquid used in blackening treatment can form a black oxide film on the surface of the bucket pin, which plays a role in rust prevention and beauty.

Production process
Raw material preparation: Purchase high-quality steel that meets the standards, with quality certification documents attached to ensure that the chemical composition and mechanical properties meet the standards. Use sawing machines and other equipment to cut the steel into suitable billet sizes, reserve margins for subsequent processing, and conduct material inspections, such as spectral analysis and hardness testing.
Rough processing: Use a lathe to rough-turn the forged blank to process the basic shapes such as the outer circle and end face, remove most of the margins, and leave a processing margin of 0.5mm-1mm for subsequent fine processing.
Fine processing: Use high-precision lathes and grinders for fine turning and grinding to ensure the dimensional accuracy of the bucket pin. The outer circle size tolerance can be controlled within ±0.01mm, and the surface roughness reaches Ra0.8-Ra1.6μm. Use drilling machines and other equipment to drill holes at specified locations to ensure the position accuracy and dimensional accuracy of the holes.
Quenching: Heat the machined bucket pin to about 850℃-880℃, keep it warm for a certain period of time, and then quickly cool it in oil or water to make the bucket pin obtain martensite structure and improve hardness and strength.
Tempering: After quenching, temper it at 550℃-650℃, keep it warm for a period of time and then slowly cool it to eliminate internal stress, stabilize the structure, and improve toughness and dimensional stability.
Surface treatment
Hard chrome plating: After pre-treatment such as degreasing and rust removal, put the bucket pin into the chrome plating tank for hard chrome plating. The thickness of the chrome plating layer is generally 0.02mm-0.05mm.
Blackening or phosphating: Choose blackening or phosphating treatment according to needs, blackening treatment in alkaline oxidizing solution, or phosphating treatment in phosphating solution to form an anti-rust protective film.
