Buying tips

When selecting a timing pulley, match the pitch and tooth profile to your belt (e.g., GT2, HTD, XL). Consider material: steel for durability and heavy loads, aluminum for lightweight and cost. Check bore size and keyway options to ensure compatibility with your shaft. Brands like Gates, Browning, and Martin are reliable for industrial use, while SDPSI offers budget-friendly choices for hobbyists.
