High Precision CNC Machined Stainless Steel Flange Sleeve Launched for Hydraulic & Mechanical Transmission Equipment

This cylindrical flange part is forged from high-grade stainless steel blanks, processed via five-axis CNC lathe and milling integrated machining to achieve ultra-precise hole positioning, smooth mirror surface finish and strict dimensional tolerance control. Evenly distributed bolt holes and long guide slots are milled with consistent depth and symmetry, guaranteeing perfect coaxial alignment during assembly to eliminate vibration and leakage risks under continuous high-pressure operation. The dense metal substrate delivers outstanding tensile strength, anti-rust and anti-corrosion performance, adapting to humid, oily and weak acid working environments without surface oxidation.

The technical team completed concentricity, pressure resistance and wear endurance tests to optimize machining accuracy and structural stability. All edges adopt chamfer polishing treatment to avoid scratching sealing gaskets during installation. Custom outer diameters, inner bore sizes, hole counts and slot layouts are available for OEM orders matching different hydraulic and mechanical equipment specifications.

To meet growing demand for precision mechanical Accessories worldwide, the factory will introduce extra five-axis CNC machining centers in Q4 2026. The enterprise will keep producing high-tolerance custom machined metal components for hydraulic system, automation and heavy machinery manufacturers globally.
