Our precision stainless steel long slender shafts are critical components engineered for the most demanding medical device applications. Manufactured from premium materials with state-of-the-art processes, they deliver unmatched reliability, safety, and performance in high-end medical equipment.

These medical device accessory shafts are characterized by their high length-to-diameter ratio and exceptional mechanical properties. They are designed to transmit force, motion, or energy with utmost precision within compact medical devices.

• Exquisite Machining: The meticulous deep hole machining process guarantees exceptional dimensional accuracy, straightness, and internal surface smoothness, which is critical for precision assembly and function.

• Superior Finish: Each shaft undergoes a specialized polishing process to achieve a flawlessly smooth, burr-free surface. This ensures patient safety, operator comfort, and facilitates easy cleaning and sterilization.

• Advanced Manufacturing: The integration of advanced cooling systems and precision tooling during the deep drilling process effectively manages thermal and mechanical stress. This prevents material deformation (such as warping or hardening) and directly enhances the product's long-term durability and fatigue life.

• Robust Performance: Built from high-quality stainless steel, these shafts provide an optimal balance of high tensile strength and exceptional corrosion resistance, ensuring reliability through repeated use and sterilization cycles.

We provide comprehensive customization services to meet your specific design and application requirements. Options include:

• Dimensional Tailoring: Custom outer diameters, inner diameters (for hollow shafts), and lengths to your exact specifications.

• Tolerance Control: Manufacturing to extremely tight geometric tolerances for diameter, straightness, and concentricity.

• Material Selection: Choice of stainless steel grades (e.g., 304, 316, or 316L VM) based on specific regulatory and performance needs.

• End-Finishing: Custom machining of shaft ends for specific interfaces, threads, or connection features.

• Primary Material: High-Quality Stainless Steel (Typically Grade 316L or 304, compliant with ASTM standards)

• Key Material Properties:

  • Excellent Corrosion Resistance

  • High Tensile and Yield Strength

  • Superior Biocompatibility

  • Outstanding Durability and Fatigue Resistance

• Surgical Instruments: Drive shafts for laparoscopic tools, surgical graspers, scissors, and staplers.

• Diagnostic Equipment: Precision components in endoscopes, ultrasound probes, and biopsy devices.

• Robotic Medical Systems: Critical actuation shafts and structural elements within surgical robotics.

• Orthopedic & Dental Devices: Guide wires, drive shafts for drills, and intricate components in various handpieces.
