Excavator Hydraulic Cylinders: The Core Power Components Driving Precise Equipment Operations

Excavator Hydraulic Cylinders: The Core Power Components Driving Precise Equipment Operations

The hydraulic cylinder (excavation oil cylinder) of the excavator is a key component that controls the movement of the boom, extension arm and bucket, directly influencing the digging force, operation accuracy and efficiency of the machine. Our hydraulic cylinder is compatible with over 30 mainstream models, including Komatsu PC200-8, Caterpillar 320D and Shantui SY215, etc. It can precisely fit various machine types ranging from 6-ton small excavators to 45-ton large equipment. The cylinder barrel is made of 45# seamless steel tube through integral forging and after grinding, the surface roughness of the inner hole reaches Ra0.8μm. It is used in combination with chrome-plated piston rods (with a coating thickness of 0.05-0.1 mm), and its wear resistance is 40% higher than that of standard hydraulic cylinders. The sealing system uses imported polyurethane oil seals + dust rings, which can achieve no leakage under a pressure of 16MPa.

Advantages Of Excavator Cylinder

The excavator hydraulic cylinder produced by our company has significant advantages: in terms of material, it is made of 45 # stainless steel seamless pipe by full forging, the cylinder barrel hardness reaches HRC30-35, the anti-deformation performance is excellent, the piston rod is chrome-plated and polished, and with imported seals, it can achieve zero leakage under 30MPa pressure.

45# Seamless Steel Forged Cylinder Barrel, With A Burst Pressure Resistance Of Up To 25mpa

The cylinder is integrally forged with 45 # high-quality seamless steel tube. After high temperature tempering treatment, the tensile strength reaches 650 MPa. Under the working pressure of 18 MPa, the boom cylinder suitable for Carter 320D has no deformation in continuous 1500-hour high-intensity operation. The anti-explosion pressure performance is 50% higher than that of the ordinary welded cylinder. The hard rock operation in mines is more reliable.

Fully Compatible With All Brands, Zero Installation Barriers

The surface of the piston rod is chrome-plated with double layers (thickness of 0.08 mm), the hardness is HRC55-60, and the abrasion resistance is improved by 30%; with the polyurethane oil seal imported from Germany, when tested on the arm cylinder of SANY SY215, there is no leakage for 8 hours under 16 MPa pressure, which is suitable for operation in humid environment, and the maintenance cycle is extended to more than 2000 hours.

Triple Leak-Proof Technology Eliminates Hydraulic Oil Loss

Features imported polyurethane seals + metal dust rings + labyrinth-style buffer structures to form a three-dimensional protective system. Maintains sealing performance in temperatures as low as -30°C or as high as 80°C, with a leakage rate controlled below 0.01ml/h, reducing hydraulic oil waste and environmental pollution risks.

Customized Services Precisely Match Operational Requirements

Supports customization of cylinder diameter (80–300 mm), stroke (200–3000 mm), and rated pressure based on excavator model and operational intensity. For special environments such as swamps or high-altitude regions, corrosion-resistant coatings or cold-resistant seals can be upgraded to ensure efficient operation in diverse environmental conditions.

Our Product

Our excavator hydraulic cylinders cover three major series of main models, fully compatible with different operational requirements. The basic YC series is suitable for 1-10 ton mini excavators, with cylinder diameters of 50-100 mm, strokes of 200-800 mm, and response speeds as fast as 0.2 seconds, precisely meeting the fine operation requirements of municipal greening and small-scale infrastructure projects; The heavy-duty KC series is designed for medium-sized equipment weighing 15-30 tons, with cylinder diameters of 120-180 mm. Featuring a reinforced cylinder barrel design, it achieves a rated working pressure of 25 MPa, making it a reliable choice for mining stripping and construction excavation; The HC series for ultra-heavy-duty applications is compatible with large excavators weighing 30-50 tons, with a cylinder diameter of 200-250 mm and a maximum thrust of up to 800 kN, specifically designed for ultra-heavy-duty scenarios such as open-pit mining and port loading/unloading.

Application scenarios cover all industries: in construction, the boom cylinder works with the stick cylinder to achieve 360° rotation, ensuring efficient lifting and crushing operations; in mining, the reinforced cylinder body withstands rock impacts, reducing downtime caused by component damage by 70%; in municipal engineering, the corrosion-resistant coating ensures stable performance of the hydraulic cylinder in wastewater and slurry environments; In the agricultural sector, lightweight design reduces fuel consumption and improves efficiency in field excavation and dredging.

 From model matching to operational conditions, our excavator hydraulic cylinders are designed with stable performance and broad compatibility at their core, making them reliable assistants in various construction scenarios.

FAQ

How to prevent sediment from entering the oil tank operating in the wetland?

The wetland oil cylinder suitable for Komatsu PC200 adopts triple protection of "double-lip oil seal + dust ring + spiral mud-proof groove". The piston rod can actively scrape off the attached sediment when it stretches out and retracts. The IP68 seal can work in 1.5 meters deep muddy water for a long time.Hubei customers used it to dredge the fish pond for 6 months, and there was no sediment residue in the cylinder after disassembly.
Prices are 15-20% lower, with a lifespan exceeding 8,000 hours (OEM parts last approximately 6,000 hours); imported seals and chrome-plated piston rods achieve zero leakage, saving over 3,000 yuan in annual maintenance costs; installation requires no modifications, with matching precision identical to OEM parts.
Fully compatible with over 20 brands, including Caterpillar, Komatsu, Sany, XCMG, Volvo, etc. Parameters strictly match the original factory specifications, and installation requires no modifications.
There are three main categories: YC series (aperture 50-100 mm) is suitable for small excavators of 1-10 tons; KC series (aperture 120-180 mm) is designed for medium excavators of 15-30 tons;The HC series (bore 200-250 mm) is suitable for large excavators over 30 tons and covers three functional cylinders: boom, bucket and stick.

Excavator Hydraulic Cylinder Selection Guide: How to Match Models and Scenarios?

Selecting the right hydraulic cylinder can increase excavator efficiency by 30%. The key points to consider are the model and the application scenario. Models are categorized by cylinder bore diameter into three series: YC Series (50-100mm) is suitable for 1-10 ton micro excavators, ideal for municipal and landscaping applications requiring precision and quick response; KC Series (120-180mm) for 15-30 ton models, with reinforced cylinder barrels for impact resistance, ideal for mining operations; HC Series (200-250mm) for excavators over 30 tons, delivering up to 800kN of thrust, suitable for port and heavy-duty applications. Application scenarios require careful consideration: choose corrosion-resistant models for wetlands (500-hour salt spray test), cold-resistant seals for northern regions with low temperatures, and the KC thickened type for mining applications.
