I've been looking on the web for suppliers of (large bore and larger
than 30 teeth)XL type aluminum timing pulleys and have been unable to
find any. Found semi-steel (sintered iron) on the McMaster-Carr site
and plastic, small bore pulleys.

Need XL (0.200, 1/5" pitch) 36 or 44, 0.500 and 0.750 inch bore.

Any suggestions to a source of pulleys ?????

Thanks ahead of time,

Harley.

Sorry, I just ended up getting the steel ones from McMaster. I would be interested in finding other suppliers, though.

Motion Industries, Stock Drive Products, are two additional that I know off hand. I have found though, that most of the sellers sell only two or three products and they are mosly all the same three product lines.

I found a supplier on the web that has 5mm pitch pulleys with flanges. Not exactly (XL, 0.200, 5.02mm) what I wanted but this will do the job.

All metric sizes from 2.5 - up, aluminum, steel, cast iron
and urethane belts.

5mm, 36 tooth, aluminum, (AT5) stock bore of 8mm, can take a max bore of about 28mm (~= 1.125" or so)
Price is reasonalbe: $18.02, less shipping.
