CNC Machined Stainless Steel Cylindrical Shaft with Multiple Through Holes – Precision Drilled Connector for Mechanical, Fluidic or Electrical Integration

This precision-machined stainless steel cylindrical shaft is a custom-engineered component designed for use in mechanical systems that require structural support combined with multi-functional connectivity. Crafted via high-precision CNC turning and drilling, this part features four through holes of varying diameters, symmetrically distributed along the shaft's body.

These through-holes serve as interfaces for component mounting, fluid transfer, or cable routing, making the part suitable for diverse applications in automation systems, fluid control modules, medical equipment, or electromechanical devices.

Key Features & Structural Highlights

Material – Stainless Steel (e.g., 304 / 316)

• Excellent corrosion resistance, especially in humid, chemical, or fluid-exposed environments

• Strong mechanical properties for rotating, supporting, or fastening roles

• Clean metallic finish with optional passivation or polishing

Cylindrical Body – CNC Turned Precision

• The main body is fully CNC turned to ensure roundness, dimensional stability, and tight tolerance control

• Surface finish can be adjusted to meet functional or aesthetic requirements (e.g., Ra ≤ 0.8μm)

Four Custom Through Holes – Varying Diameters

• Four precision-drilled holes pass through the shaft horizontally

• Diameters are non-uniform, allowing multiple functions or connection types within one part

• Hole spacing and position are engineered for symmetry and functional alignment, enabling:

  • Screw or pin fastening

  • Sensor or wire pass-through

  • Fluid/gas channeling in compact systems

  • Mounting interface for bracket or housing

Optional End Features

• Ends can be customized with chamfers, flats, threads, or cross-drilled holes as required by your design

Typical Applications

This component is ideal for systems requiring mechanical alignment + multifunction routing, such as:

• Fluidic manifolds or micro-piping bases

• Sensor mounts with wire pass-through capability

• Rotating connectors in automation equipment

• Custom jigs, fixtures, or mechatronic modules

• Medical devices with internal fluid or vacuum paths

Its structure supports mechanical fixation, fluid/electrical transmission, and modular integration, all in one compact form.
