- Metal Sheets: Cold-rolled high-carbon steel (SPCC) or stainless steel (SUS304), thickness 0.8-1.5mm.
- Accessories: Chrome steel balls (G10 grade, Ø2-3mm), glass-filled nylon retainers, lithium grease.

- Progressive Die Stamping: High-speed presses (300-600 SPM) punch mounting holes and create features like connection notches (to reduce weight and adapt to uneven surfaces).
- Roll Forming: C/U-shaped or "几"-shaped profiles (for load distribution) are formed via

- Integrated Stamping: One-piece structures (e.g., base plates with guide rails) eliminate welding, enhancing rigidity.
- Automated Welding: Tail hooks and adjustment plates are welded at 5-8 pcs/min, compatible with 250-600mm lengths.
- Surface Grinding: Contact surfaces polished to Ra≤0.8μm for smooth sliding.

- Quenching & Tempering: Oil quenching at 820℃ + tempering at 180℃ achieve HV550 surface hardness.
- Anti-Corrosion Coating: Electrophoretic coating (20-30μm) or Zn-Ni electroplating (8-12μm) passes 480hr salt spray test.

- Ball/Roller Loading: Retainers molded with ±0.02mm precision; vibratory feeders place 40-60 balls per slide.
- Hydraulic Pressing: Inner/outer rails + retainers assembled under 50-80N preload.
- Grease Sealing: Lithium grease (NLGI 2) injected and sealed via ultrasonic welding.

- Smoothness Test: 100,000 cycles at 0.3m/s, friction coefficient <0.15.
- Load Test: Static load ≥60kg; 20kg dynamic fatigue test (100k cycles) without deformation.

- Rust Prevention: VCI paper + PE film for 24-month storage.
- Laser Engraving: Load rating (e.g., 60kg), certifications (BIFMA), and batch codes marked.
