What surface treatment options are available for synchronous pulleys?

Raw metal components face surface degradation when exposed to humid assembly plants, chemical washdowns, or constant mechanical friction. Applying the proper surface finish extends part life and ensures clean operation:

  • Ordinary Oxidation: The baseline standard treatment for aluminium components. It establishes reliable micro-level corrosion protection while maintaining exact dimensional tooth tolerances.
  • Hard Anodizing: Recommended for high-speed or high-abrasion environments. It forms a dense, hardened ceramic layer on aluminium profiles to drastically lower tooth wear during high-cycle running.
  • Blackening (Black Oxide): A practical chemical conversion coating for 45# steel components. It improves anti-rust properties and delivers a sleek, dark aesthetic finish without changing machined dimensions.
  • Zinc Plating (Galvanizing): Creates a sacrificial metallic barrier against moisture. Ideal for outdoor general industrial machinery or humid textile factories.
  • Nickel Plating: Combines premium corrosion resistance with a bright, clean look. Perfect for components facing light chemical exposure or requiring clean room compliance.

B2B Specification Guarantee: Sables guarantees that all surface treatments are carefully calibrated so that chemical layers do not compromise the pitch diameter or precision tooth profile, ensuring smooth engagement with your timing belts.
