Frequently Asked Questions

Q: What belt width is this XL timing pulley compatible with?

A: This XL timing pulley has a groove width of 11mm, making it designed for use with 10mm wide XL timing belts. The 5.08mm pitch matches the standard XL belt profile for a precise, synchronous fit.

Q: What materials are used in this timing pulley?

A: The pulley body is made from lightweight aluminum alloy, while the retaining flanges on both sides are constructed from galvanized iron to prevent corrosion and keep the belt securely aligned during operation.

Q: Can I use this pulley for a CNC machine or 3D printer?

A: Yes! The XL series timing pulley is widely used in CNC routers, 3D printers, laser engravers, and robotics. Simply select the tooth count and bore size that matches your drive shaft diameter and gearing requirements for a direct drop-in fit.

Q: How do I choose the right bore size and tooth count?

A: Select the bore size that matches your motor or drive shaft diameter (available from 5mm up to 30mm). Choose the tooth count based on your desired gear ratio — more teeth means a larger pulley diameter and lower rotational speed relative to the motor.
