What's the difference between the 20T, 40T and 60T pulleys?

The 'T' number is the tooth count, so a 20T pulley has 20 teeth and a 60T has 60 teeth. A pulley with more teeth will have a larger diameter, which affects your drive ratio and speed. All these pulleys have the same 3mm tooth pitch to match an HTD 3M belt.

Will this pulley fit on an 8mm motor shaft?

You need to check the 'Bore Size' option for the specific pulley you select, as different tooth-count pulleys come with different standard bore sizes. If an 8mm bore isn't listed as an option for the pulley you need, it won't fit your shaft without modification.

Which width of timing belt should I use with this pulley?

These pulleys are designed to be used with either a 10mm or 15mm wide HTD 3M timing belt. Just make sure the belt width you choose is the same as, or slightly narrower than, the pulley width you order.

This HTD 3M timing pulley works with a matching belt to make exact, repeating movements in your machine. You can get it with different tooth counts, from 20 to 60. This lets you set the gear ratio you need for speed or power. It fits belts that are 10mm or 15mm wide. Features and Benefits - Many tooth counts (20T, 30T, 40T, 60T) - You can adjust the final speed and power output of your drive. - Machined aluminum build - It's strong but light, which lowers the overall weight of the system. - Fits two belt widths - It's made to work with both 10mm and 15mm wide HTD 3M belts. - Comes with two set screws - These hold the pulley tight to a motor or shaft. This stops it from slipping during use. Applications - Laser cutters and engravers - It moves the laser head smoothly, helping make clean, accurate lines. - Small robots - Useful for building drive systems or arms that need exact placement. - Automated camera sliders - It moves the camera along the belt at a steady, controlled speed.

Q: What material are these pulleys made from? A: These pulleys are machined from an aluminum alloy. This material gives them good strength for transferring power while also being lightweight, which helps keep the rotational inertia of your system low.. Q: What material are these pulleys made from?

A: These pulleys are machined from an aluminum alloy. This material gives them good strength for transferring power while also being lightweight, which helps keep the rotational inertia of your system low.. Q: Can I use a 15mm wide timing belt with the pulley marked for 10mm belts? A: You shouldn't, as the belt would overhang the pulley flanges and would not be properly supported. It's important to match the belt width to the pulley's specified width—use a 10mm belt with a 10mm pulley, and a 15mm belt with a 15mm pulley..

Q: Do I need to buy screws separately to attach the pulley? A: No, each pulley comes with two set screws already included. You can use these to secure the pulley tightly against the flat on a D-shaft or directly onto a round shaft.. Q: Do I need to buy screws separately to attach the pulley?
