Can anyone recommend a US supplier for timing belts and pulleys with reasonable prices? Anything I should look for in particular?

Thanks

B&B Manufacturing.

That would probably depend on the specific application. Belts and pulleys are used for many different things.

Thanks Gerry,

Using them to drive ballscrews from my stepper motors (570oz)

Are you reducing/increasing the speed, or just transferring motion? If you use it to reduce speed, in hopes of getting more torque, you're going to be disappointed, since steppers have less torque the faster they run. If you're trying to increase the speed this way, you lose resolution. If all you're doing is transferring motion, you can do that easier with spider-type couplings.

Thanks Andrew. I'm not looking to change any ratios, just fold the system on itself so I can align the steppers parallel to the ballscrews and not have them sticking out from the machine.

Try SDP/SI.

I've bought lots of belts and pulleys from them.

I get mine from a visit to a local bearing supply house, they often either carry them or can bring them in from their supplier.
