Finding belt pulleys?

[eklaw]

Our team is struggling to find the belt pulleys that we need. We are looking for 3-4" diameter belt pulleys that fit belts 2" thick and have a .5" bore. Even if you don't have time to find this specific part, links to suppliers would be greatly appreciated. Thanks!

We have but none of their pulleys have a large enough diameter/ width for our application.

May i ask what you are using them for?

Check out McMaster-Carr http://www.mcmaster.com/#timing-belts/=l1f6zu

Another option is Gates that is a big sponsor for FIRST. http://www.gates.com/index.cfm?location_id=4978

We haven't used either one extensively but have heard that Gates is the better and more reliable option.

We want to use a belt in a linear shooter direct driven off mini cims.

This is slightly off topic, but Brecoflex (http://www.brecoflex.com/index.php?) offers a greater variety of belt surface materials (http://www.brecoflex.com/index.php?CATID=1&SCATID=6&SMENID=22) and features that could give you a better grip on the Frisbee than other belts that are designed purely for power transmission. I have never dealt with them or their products before, but this search (http://www.chiefdelphi.com/forums/search.php?searchid=4568947) seems to suggest that others on this forum have had positive experiences with them.

Last year we got pulleys from B&B Manufacturing http://www.bbman.com/. If you ask, they will give you a FIRST discount (or at least they did last year).
