High Corrosion Resistance Ultra-High Precision Tolerance Custom Machining Dowel Pin and Locating Pin

High-precision cylindrical dowel pin is a core mechanical hardware component specially manufactured for accurate positioning, structural connection and assembly calibration in industrial machinery and automation equipment. Adopting strict precision turning, grinding and mirror polishing processes, this cylindrical locating pin achieves ultra-high dimensional accuracy, smooth surface finish and excellent straightness. It is widely used to eliminate assembly gaps, prevent component displacement, and ensure consistent repeat positioning accuracy during mechanical fitting.

Different from ordinary standard pins, our dowel pins feature tighter tolerance, better wear resistance and stronger shear stability, perfectly solving loosening, shaking and positioning deviation problems caused by long-term mechanical operation. We provide full custom machining services, including customized diameter, length, chamfer, step shape, groove structure and special size dowel pins to meet diverse mechanical connection and locating requirements.

• Ultra-High Precision Tolerance: Machined under strict micron-level tolerance control, ensuring zero-error precise locating and seamless assembly for precision mechanical structures.
• Excellent Wear & Shear Resistance: High-density material and fine surface treatment greatly enhance friction resistance and load-bearing capacity, suitable for long-term repeated assembly and high-frequency movement.
• Stable Mechanical Positioning: High straightness cylindrical design effectively prevents component offset, structural shaking and assembly deviation, improving overall equipment stability.
• Smooth Burr-Free Surface: Mirror polishing treatment ensures smooth insertion and extraction, no jamming during assembly and disassembly, improving production efficiency.
• Strong Compatibility: Suitable for mold positioning, equipment assembly, fixture calibration, mechanical connection and multi-layer stacking installation scenarios.
• Full Custom Machining Support: Support non-standard size, special-shaped structure, step pin, grooved pin and chamfer customization according to drawings and samples.
