Cat320B/C/D​ Caterpillar Excavator: Durable, High - Quality Boom Seal Kit and Hydraulic Cylinder Seal Kit Built to Withstand Heavy - Duty Operations

The cylinders of Caterpillar excavators have the following characteristics:

High Strength and Durability

• Manufactured with high-quality materials: The main components of Caterpillar excavator cylinders, such as the cylinder barrels and piston rods, usually adopt high-strength alloy steel. Through special heat treatment processes, they possess extremely high strength and hardness. They can withstand frequent high-pressure impacts and long-term heavy-load operations, reducing deformation and wear and extending the service life.

• Advanced surface treatment: In order to improve corrosion resistance and wear resistance, the surface of the cylinders will be treated with processes such as chrome plating and nickel plating to form a hard and smooth protective film, effectively preventing the corrosion of hydraulic oil and the erosion of the external environment, and maintaining good performance even under harsh working conditions.

High Precision and Reliability

• Precise processing technology: Using advanced processing equipment and precise processing technology, it ensures that the dimensions of all components of the cylinder are of extremely high precision, and the fit clearance is uniform. This guarantees the smooth movement and sealing performance of the cylinder, reduces the occurrence of internal and external leakage, and improves work efficiency and reliability.

• High-quality seals: Equipped with high-quality seals, which have good elasticity, wear resistance and oil resistance. They can maintain good sealing performance in a high-pressure and high-temperature working environment, effectively preventing hydraulic oil leakage and ensuring the stability of the working pressure and thrust of the cylinder.

Efficient Working Performance

• Large thrust and long stroke: According to the requirements of different models of excavators, cylinders of different specifications are designed, which can provide greater thrust and stroke, meeting the force and displacement requirements of excavators in various operations such as excavation, lifting and slewing, and improving operation efficiency.

• Quick response: The structural design of the cylinder and the hydraulic control system are optimized, making its response speed fast. It can quickly achieve the telescopic action, cooperate with other working devices of the excavator, and realize efficient and smooth operation.

Good Compatibility and Versatility

• Good matching with the whole machine: When designing the cylinders of Caterpillar excavators, full consideration is given to their compatibility with the whole excavator. They can perfectly match the hydraulic system, frame, working devices, etc. of the excavator, ensuring that the performance of the whole machine is fully exerted.

• Strong versatility of some components: Among different series and models of Caterpillar excavators, some components of the cylinders have high versatility. This not only facilitates maintenance and repair, reduces the maintenance cost for users, but also improves the supply efficiency of spare parts.
