FAQ:

Q: Why are the teeth on a GT2 pulley curved?

A: Similar to HTD timing belt pulleys, their teeth are curved for high strength. The curved teeth create positive grip engagement with timing belts, so these pulleys do not require re- tensioning— unlike drives using V-belts or sheaves.

Q: When to use a GT3 timing belt pulley?

A: For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics. Similar to HTD timing belt pulleys, their teeth are curved for high strength.

Q: How many flanges are in the Max belt idler?

A: Timing Belt Idler Pulleys For Max. Belt Wd., mm OD, mm Number of Teeth Pitch, mm Number of Flanges 12 90 32 8 2 20 146 30 14 2 21 90 32 8 2 7 more rows …

Q: What kind of material is a pulley made out of?

A: Made from iron or steel, these pulleys are strong and wear- resistant. The black oxide coating protects the pulleys from corrosion in dry environments. Trapezoidal teeth on the outside of the pulley fit into teeth inside your timing belt— select a pulley that matches your belt trade size.
