In the world of modern automation and machinery, hydraulic and pneumatic components are the lifeblood of motion control. At Maozhong, we specialize in manufacturing precision-engineered metal components for hydraulic and pneumatic systems — including custom pistons, sleeves, guides, and connectors.
Hydraulic components work with pressurized liquid (typically oil).
Pneumatic components use compressed air or gas for actuation.
Despite their operating mediums, both systems require tight tolerances, leak-proof performance, and reliable mechanical strength — all of which depend on expertly made hardware components.
These parts, like the one shown in the image above, are made from high-grade stainless steel or alloy steel to endure high-pressure environments.
Machined for perfect fit, our valve seats and cylinder sleeves ensure efficient fluid dynamics and long-term durability.
We provide O-ring grooves, chamfered bores, and custom seal tracks to meet your specific assembly needs.
All components go through CNC machining, heat treatment, and QC inspection to ensure ±0.01 mm tolerance.
Whether you need a custom part or complete prototype assistance, our team supports drawings, reverse engineering, and batch production.
From North America to Europe, we export regularly with fast lead times and multilingual customer support.
