High-precision cylindrical dowel pin for mechanical connecting and locating applications with full custom machining capabilities.
Product Overview
Stainless Steel Support Shaft Pin, also known as cylindrical dowel pin or mechanical locating pin, is a high-precision solid mechanical fastener widely used for equipment positioning, structural support, rotational connection and assembly locking.
Manufactured from high-quality 304/316 stainless steel, this cylindrical pin features high hardness, uniform density, excellent wear resistance and strong shear resistance. After precision CNC turning, grinding and deburring treatment, the pin body achieves ultra-smooth surface, strict tolerance control and high straightness, ensuring zero-gap matching and precise positioning during mechanical assembly.
It effectively solves positioning deviation, structural shaking and loose connection problems of mechanical parts. Suitable for repeated assembly, high-frequency movement and long-term load-bearing working conditions. We provide full non-standard custom machining according to customer drawings and samples, including custom diameter, length, chamfer, groove and special-shaped structure.
Core Features
High Precision Dimensional Stability: Strict micron-level tolerance control, high straightness and smooth cylindrical surface, ensuring accurate positioning and no assembly deviation.
Premium Stainless Steel Material: Adopts 304/316 stainless steel, featuring rust-proof, anti-corrosion and oxidation-resistant performance, suitable for humid, outdoor and harsh industrial environments.
High Hardness & Wear Resistance: Excellent surface hardness and mechanical toughness, resistant to friction and long-term reciprocating movement, not easy to deform or wear.
Strong Support & Shear Resistance: Solid one-piece structure provides outstanding load-bearing capacity and shear strength, stabilizing mechanical structural connection.
Smooth Assembly & Reusable: Fine polished surface without burrs, easy to install and disassemble, suitable for repeated assembly and maintenance.
Full Non-Standard Customization: Support custom pin diameter, length, chamfer angle, step shaft, groove and special structural size to meet personalized mechanical matching needs.
Stainless steel cylindrical support shaft pins are widely used in automation equipment, precision mechanical instruments, electronic equipment, automotive parts, communication devices, industrial molds and general machinery assembly.
Mainly used for precise positioning, structural support, rotating connection, gap fixing and component anti-shake assembly, serving as essential precision hardware for mechanical stability.
