We specialize in the manufacture of rear flange hydraulic cylinders, engineered for robust support and precise hydraulic performance through a secure rear flange mounting design commonly used in heavy-duty industrial applications.
Features of Rear Flange Hydraulic Cylinders
- Sturdy Rear Flange Mounting
The rear flange serves as a solid mounting base at the cylinder’s back end, providing enhanced stability and alignment within machinery. This design supports axial and radial loads firmly, reducing stress on the cylinder during operation. - Precision Engineering and Customization
Each cylinder is CNC-machined for exact tolerances to ensure perfect flange flatness, concentricity, and proper seal fitment. Flanges can be customized in dimension and bolt pattern to meet diverse mounting requirements. - Durable Construction and Finishing
Using premium steel or alloys, the cylinder barrel and flange are either integrally machined or welded with high-precision techniques such as circular or MIG welding to ensure structural integrity. Critical surfaces receive hard chrome plating or polishing for corrosion resistance and wear protection.
Rear Flange Cylinder Manufacturing Process
- Material Selection and Cutting
High-grade steel tubes and plates are cut to size and prepared for machining, ensuring raw materials meet stringent quality standards. - Machining Operations
The cylinder barrel, rear flange, and other components are machined on lathes and milling machines. The flange surfaces are precisely finished, and hydraulic oil ports are drilled using live tools for accurate flow control. - Welding and Assembly
The rear flange is welded to the cylinder barrel using automated circular welding machines, often using locating pins and holes to ensure coaxial alignment during welding. Bearings are pressed into place immediately after welding while parts are still warm for easy fitting. - Sealing and Component Installation
After welding, the cylinder is fitted with piston rings, seals, and lubrication nipples. All parts are lubricated and assembled carefully to avoid damage and ensure smooth operation. - Testing and Final Inspection
Completed cylinders undergo rigorous hydraulic pressure and leak tests to verify durability and performance under load. Dimensional checks confirm adherence to engineering specifications. - Surface Finishing
Final treatments such as painting or coating are applied for environmental resistance and extended service life.
