Stainless Steel Flange

Rotary shaft alignment and rigid coupling in hydraulic or pneumatic systems depend on the precise geometry of this flanged interface. The component features a central through-bore surrounded by a raised hub, which acts as a locating feature to ensure concentricity with mating shafts or bearings. Six evenly spaced mounting holes on the outer perimeter allow for secure bolting to machine frames or adjacent components, distributing clamping forces uniformly across the assembly.

Achieving tight tolerances on the bolt circle diameter and maintaining perpendicularity between the sealing face and the central axis are critical for preventing leakage and vibration. The visible brushed surface finish indicates a post-machining treatment that enhances corrosion resistance and aesthetic uniformity, typical for stainless steel parts used in demanding environments. Manufacturing requires careful fixturing to minimize deformation during the boring and facing operations, ensuring that the flatness of the contact surfaces meets strict sealing requirements.

Leveraging over 12 years of experience in precision CNC machining, our facility utilizes high-end turning and milling centers to produce such non-standard mechanical parts with consistent quality. We support a wide range of materials including stainless steel, aluminum, and alloy steels, offering secondary processes like passivation or electropolishing to meet specific industry standards.
