The 910305650 Cylinder Barrel is a precision‑machined hydraulic cylinder tube designed for XCMG excavators. As a non‑engine auxiliary component, this barrel forms the main body of hydraulic cylinders, providing a durable, wear‑resistant bore for the piston and rod assembly. Manufactured from high‑strength steel with a honed internal surface, the 910305650 cylinder barrel guarantees exceptional pressure integrity, low friction, and long service life in the most demanding construction, mining, and demolition applications.
The 910305650 Cylinder Barrel is a precision‑machined hydraulic cylinder tube that forms the core of hydraulic actuators in XCMG excavators. As a non‑engine auxiliary component, this barrel provides the cylindrical chamber where the piston and rod move, converting hydraulic pressure into linear force. Its robust construction and precise internal geometry ensure efficient power transmission, smooth operation, and long‑term reliability.
The barrel is manufactured from high‑strength seamless steel tube, chosen for its superior mechanical properties and resistance to pressure fatigue. The internal surface is honed to a mirror‑like finish, reducing friction with the piston seals and extending the service life of the cylinder. This component is a direct OEM replacement, restoring original cylinder performance and ensuring safe, reliable machine operation.
The 910305650 Cylinder Barrel features a honed internal surface with a roughness of Ra ≤ 0.4 µm, providing an optimal sealing surface for the piston seals. This smooth finish reduces seal wear, minimises internal leakage, and ensures consistent cylinder performance over thousands of operating cycles. The honing process also creates a cross‑hatch pattern that retains a thin film of lubricating oil, reducing friction and preventing scoring.
The 910305650 Cylinder Barrel offers a range of features that enhance hydraulic cylinder performance and durability. Its seamless steel construction provides excellent pressure‑containment capability, with a maximum working pressure of 35 MPa, making it suitable for the most demanding excavator applications. The honed bore ensures low friction and minimal leakage, improving overall system efficiency.
The barrel’s robust wall thickness and high‑quality material provide resistance to deformation and fatigue, ensuring reliable operation even under continuous heavy loads. The precision‑machined ends allow for accurate welding of cylinder heads and flanges, simplifying assembly and ensuring leak‑free connections. By choosing the genuine 910305650 cylinder barrel, operators can be confident in the integrity and performance of their hydraulic cylinders.
The barrel’s compatibility with standard seals and wear rings simplifies rebuilding and maintenance. Its long service life reduces the frequency of cylinder replacements, lowering overall operating costs and minimising downtime.
The 910305650 Cylinder Barrel is manufactured from high‑grade steel that has been tested for yield strength, tensile strength, and impact resistance. The material is selected to withstand the repeated pressure cycles and shock loads typical of excavator operations, ensuring that the barrel does not develop stress fractures or deform over time. This durability makes it an ideal component for heavy‑duty applications such as mining, quarrying, and demolition.
The 910305650 Cylinder Barrel is specifically designed for use in XCMG hydraulic excavators, including models such as XE210, XE240, XE305, and other XE series machines. It is used in a wide range of hydraulic cylinders, including boom cylinders, arm cylinders, and bucket cylinders, where it provides the structural foundation for linear actuation.
This cylinder barrel is also compatible with other XCMG equipment that utilizes similar cylinder dimensions, such as wheel loaders, crawler cranes, and backhoe loaders. Its standard internal diameter and length make it a versatile replacement part for various hydraulic applications.
When replacing a damaged or worn cylinder barrel, using the genuine 910305650 part ensures the correct material grade, hardness, and dimensional accuracy. Aftermarket barrels may not meet the same quality standards, potentially leading to premature failure and safety hazards. Trust only genuine XCMG components to maintain the performance and reliability of your equipment.
Installing the 910305650 Cylinder Barrel requires mechanical expertise and specialised tooling. Before installation, inspect the barrel for any shipping damage and ensure that the internal bore is clean and free of debris. When assembling the cylinder, use appropriate seals and follow the manufacturer’s torque specifications for end caps and fittings.
During reassembly, ensure that the piston and rod are aligned correctly to prevent scoring of the bore. After installation, test the cylinder for leaks and smooth operation. Regular inspection of the barrel is recommended as part of routine maintenance. Check for signs of scoring, corrosion, or pitting on the internal surface. Replace the barrel if any damage is detected to maintain system integrity.
Keeping a spare 910305650 cylinder barrel on hand can minimise downtime during cylinder rebuilds. Always use genuine XCMG parts to ensure proper fit and performance.
The 910305650 Cylinder Barrel is manufactured in ISO 9001 certified facilities under strict quality control. The seamless steel tube is sourced from approved suppliers and undergoes chemical and mechanical testing to verify its properties. The honing process is performed on CNC honing machines to achieve consistent bore geometry and surface finish.
Each barrel is inspected for internal diameter, roundness, straightness, and surface roughness to ensure it meets XCMG’s demanding specifications. The barrel is pressure‑tested to verify its integrity before shipment. These quality measures ensure that every cylinder barrel delivers the performance and reliability expected from a genuine XCMG component.
