Pulleys are XL series (extra light) and have trapezoidal teeth. Pulleys are aluminum, has low density, but high strength, excellent electrical conductivity, thermal conductivity and corrosion resistance, which is more corrosion resistant than steel. 

These Timing Pulleys are for use with XL standard Timing Blts with 5.08mm (0.2 inch) tooth pitch, in 10mm (3/8 inch) max. width belts.

These pulleys are widely used in 3d printers , cnc machines and other transmission applications. It is widely used in various types of mechanical transmission in various industries such as textiles, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automobiles, CNC, 3D printers, robotics, etc.

High precision, the teeth of the pulley engage with the belt stably and will not slip.

Smoother, smoother transmission cushion, low noise, low loss.

More accurate, with accurate transmission ratio.

High efficiency, high transmission efficiency, more time-saving.

For tight spots, choose a pulley without a hub.

Tip：
- The external dimensions may vary according to the production batch, and the actual dimensions shall prevail. Please understand.
- Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.
