Cat 330c Excavator Hydraulic Cylinder Hard Chrome Plated Corrosion Resistant

Cat 330c Hydraulic Cylinder

Cat 330C is a 33 ton large excavator model produced by Caterpillar Inc. The hydraulic cylinder that matches it is a specially designed and customized accessory for this model.

1, Overview
The hydraulic cylinder of Cat 330C excavator is a key power actuating component that drives its working device to perform core actions such as excavation, lifting, loading and unloading. Mainly includes:
· Bucket Cylinder: controls the curling and releasing of the bucket.
· Stick Cylinder: controls the extension and retraction of the stick (forearm).
· Boom Cylinder: controls the lifting and lowering of the boom (upper arm).
· (Optional) Bulldozer cylinder: controls the lifting and lowering of the bulldozer.

2, Core Design and Features
1. Excellent sealing technology:
· Using Cat's proprietary polyurethane seals and Glyd Ring ®  Guiding ring.
· This combination can effectively reduce internal leakage, maintain strong and powerful oil cylinders, and greatly extend the service life of seals, with strong resistance to pollution.
2. Robust structural design:
· Cylinder barrel: forged from high-strength carbon steel, precision machined and honed on the inner wall, with extremely low surface roughness, reducing the wear of piston seals.
· Piston rod: Made of high-strength alloy steel and treated with hard chrome plating on the surface, it has extremely high wear resistance and corrosion resistance, and can effectively cope with harsh working environments.
· Welding process: All key welds are welded by robots to ensure deep penetration and 100% consistency, greatly improving structural strength and reliability.

3. Optimized buffer design:
·The piston is designed with buffering structures at both ends, which can smoothly decelerate at the end of the stroke, effectively eliminate hydraulic shock, reduce pressure peaks and vibrations of the entire hydraulic system, and protect the cylinder itself, oil pipes, and the entire hydraulic system.

4, Application 
The Cat 330C hydraulic cylinder is designed specifically for Cat 330C excavators, therefore its application is consistent with the main engine and widely used in:
· Earthwork excavation
· Mining and excavation
· Construction of buildings
· Road and bridge construction
· Large scale material handling
