Frequently Asked Questions
Trapezoidal teeth (like XL, L, H) are traditional designs for general power transmission, whereas Arc toothed (HTD, GT series) profiles offer higher torque capacity and reduced noise by distributing the load more evenly.
At high rotational speeds, even minor imbalances in cast iron can cause significant vibration. Grade 6.3 balancing ensures smooth operation, prevents premature bearing failure, and protects the engine's structural integrity.
Yes, we offer custom inner bores ranging from 2mm to 200mm with H7 precision tolerance to ensure a perfect fit for your specific shaft requirements.
For high-corrosion areas, we recommend Galvanization or Anodizing (for aluminum). Black Phosphate is excellent for general wear and friction reduction in standard industrial settings.
For high-load applications, Steel C45 and Cast Iron GG25 are recommended due to their superior hardness and structural strength compared to aluminum.
Absolutely. Our pulleys are manufactured to meet international standards for HTD3M, 5M, 8M, and GT2, GT3, GT5 profiles, ensuring full compatibility with industry-standard timing belts.
