Supplier's note

  1. Key Technical Breakthroughs:

    • Material Upgrades: The Pro model’s stainless steel construction provides 40% better corrosion resistance than cast iron, ideal for marine or chemical environments.
    • Precision Grooves: The Advanced model’s ±0.05mm tolerance ensures 20% faster belt alignment compared to industry standards.
    • Temperature Range: The Pro model’s expanded -40°C to 120°C range accommodates extreme industrial conditions.

  2. Optimal Version Selection:

    • Base Model (SPA): Suitable for standard conveyor systems where cost efficiency is prioritized.
    • Advanced Model (SPB): Ideal for medium-duty applications requiring enhanced durability (e.g., food processing machinery).
    • Pro Model (SPC): Best for high-stress environments (e.g., mining, chemical plants) needing extreme resilience and precision.

Example: With the Pro model’s 800N load capacity, you can handle heavy-duty conveyors 60% beyond the base model’s limits. Its stainless steel material ensures safe operation in corrosive settings, extending equipment lifespan by 30%.
