Frequently Asked Questions
For high-load applications, GG25 Cast Iron or C45 Steel is recommended due to their superior strength and wear resistance compared to aluminum.
T-toothed pulleys use a trapezoidal profile suitable for general synchronization, while HTD (arc-toothed) profiles are designed for higher torque transmission and reduced belt wear.
Yes, we provide inner bores ranging from 2mm to 200mm with H7 precision, and we can customize any specific bore size to fit your shaft.
Dynamic balancing (Grade 6.3) eliminates centrifugal imbalances, reducing noise and vibration, which protects the bearings and extends the overall machine life.
We offer Black Phosphate, Black Oxide, and Galvanization for steel and iron pulleys, and Anodizing for aluminum pulleys to ensure maximum corrosion resistance.
Absolutely. Our timing pulleys are specifically designed to synchronize the crankshaft and camshaft, ensuring valves open and close at the precise moment for optimum performance.
