1. Hard-Anodized Aluminum Side Plates The black, teardrop-shaped components are CNC-machined side plates for professional pulleys or connectors. Material: Forged or billet Aluminium Alloy (6061/7075). Finishing: Hardcoat Anodization (Type III), which provides a sapphire-hard surface that is resistant to scratches, salt-spray corrosion, and UV degradation. Design: Ergonomic, weight-optimized profiles that maintain high Breaking Strength (MBS) while reducing the climber's load. 2. Precision Stainless Steel Axles & Pins (軸件) To the left of the plates are the internal "bones" of the assembly:

Multi-Stage Precision Shafts These are critical mechanical components designed for power transmission and rotational stability. They feature a **multi-stage diameter design**, meaning the shaft has several different thickness levels along its length to accommodate bearings, gears, or housings. 2. Key Technical Features precision Threading: Two of the shafts feature high-precision external threads at the tip, designed for secure fastening with nuts or within threaded assemblies. Keyways and Slots:You can see precision-milled longitudinal slots (keyways) and transverse holes. These are used to lock gears or pulleys onto the shaft, ensuring they rotate together without slipping. We specialize in sourcing and procuring various types of metal machining parts, components

1. Complex Cylindrical Housings and Sleeves Precision Sleeves: The large, hollow circular parts at the top represent precision sleeves or outer casings. They feature internal grooves and specific cut-outs, likely used as protective housings for bearing assemblies or sensor units. Slotted Collars:The ring-like part with vertical slots is a specialized collar, often used in mechanical locking mechanisms or for heat dissipation in high-speed rotations. 2. Multi-Stage Precision Shafts and Axles Stepped Shafts:The long, slender components in the middle row are classic examples of multi-stage shafts. They feature various diameter changes, precision-ground surfaces, and specialized tips. These are critical for power transmission in automotive or industrial robotics. Knurled Adjustment Pins: One of the longer shafts features a **knurled head** (textured surface), designed for manual grip and fine-tuning in mechanical calibration equipment. 3. Specialized Valves and Connectors Hydraulic/Pneumatic Fittings:Several components feature tapered ends and internal threading, resembling high-pressure valve stems or fluid connectors. Their smooth finish is essential for maintaining airtight or watertight seals. Nozzle Components:The smaller, pointed parts are likely high-precision nozzles or injectors used in medical or fuel-delivery systems. 4. Precision Washers and Positioning Discs Perforated Discs:The flat, circular parts at the bottom-left are positioning washers or distribution plates. They feature precisely drilled hole patterns (bolt circles) to allow for fluid flow or secure mounting in an assembly. Recessed End Caps:The disc with a deep center indentation serves as a mechanical end cap or a seat for a rotating component. 5. High-Precision Technical Features Material Integrity:These parts appear to be crafted from high-grade **Stainless Steel and Aluminum Alloy, offering a balance of durability and corrosion resistance.
