stainless guide pin
wda-GP-45553-001
Engineered for critical positioning in high-accuracy systems, our Precision Stainless Steel Guide Pins deliver unmatched dimensional precision and wear resistance, ideal for injection molds, CNC machine tools, and medical robotics. Crafted from 303/304 stainless steel with tight tolerances (±0.002mm), these pins ensure smooth motion and long service life in demanding environments.
Premium Material Performance
Alloy Options:
303 SS (free-machining, hardness 180-210 HB) for high-speed cutting applications (e.g., automated assembly lines).
304 SS (passivated, ASTM A967) for corrosion resistance in wet environments (e.g., food processing equipment).
Heat Treatment: Stress relieving (190°C, 2 hours) reduces internal stresses, improving fatigue life to ≥10^6 cycles under 50% load.
Precision Machining
Swiss-Type Lathes: Achieve diameter tolerances ±0.002mm and surface finish Ra ≤0.4μm, with straightness ≤0.01mm/m verified by laser alignment.
Grinding & Polishing: Micro-polished tips (Ra ≤0.2μm) reduce friction by 30% compared to standard pins, minimizing wear on mating bushings.
Design Customization
Head Styles: Flat, rounded, and threaded heads (M2-M12, ISO metric), with optional lubrication grooves (0.5mm depth) for self-lubricating systems.
Coating Options:
PTFE coating (5-10μm) for low-friction environments (coefficient of friction ≤0.15).
Black oxide (Fe3O4) for moderate corrosion resistance (500h salt spray).
Injection Molding: Guides mold cores in automotive part production, ensuring alignment accuracy (±0.01mm) and reducing flash formation by 40%.
Medical Robotics: Critical components in surgical arms, with 316L SS variants meeting USP Class VI biocompatibility standards.
CNC Machine Tools: Linear guide pins in ball screw systems, maintaining positioning accuracy (±0.005mm) in high-precision machining centers.
Precision Assurance
100% inspection using CNC CMMs (resolution 0.001mm), with detailed reports including roundness (≤0.003mm) and cylindricity (≤0.005mm).
Material Traceability
Sourced from AISI-certified mills, each pin is laser-marked with lot number and heat treatment date, compliant with IATF 16949 for automotive applications.
Rapid Turnaround
Stocked standard sizes (diameter 3-25mm, length 20-200mm) with 5-day lead time, and expedited machining (3-day rush service) for urgent orders.
Engineering Support
In-house design team provides DFMA feedback, optimizing pin geometry for press-fit applications (e.g., interference fits with 0.001mm precision).
