Model Forum / General / Models / February 2009Pulley suppliers
I'm looking for a source of A section steel pulleys 5/8" shaft 1x 55mm and 1 x 65mm. The smallest RS carry is 80mm This is on behalf of someone else and yes I could make them but they are not that close and frankly don't want to spend the time but if anyone knows of a supplier I'd be grateful. Online/mail order would be a distinct advantage. TIA Bob > I'm looking for a source of A section steel pulleys 5/8" shaft 1x 55mm > and 1 x 65mm. [quoted text clipped - 8 lines] > > Bob Bob You could try https://sdp-si.com/eStore/Direct.asp?GroupID=548 this company do a number of different sizes and do mail order. I xcould not see your exact sizes and I have never used them. Also Chronos do pulleys but only a few sizes and not exactly what you are after. In the past got all my pulleys from Picador, but they have gone now I think. Cheers Dave > The smallest RS carry is 80mm There's a reason behind that: The smallest allowable diameter for section A is 90 mm. So they are already a bit below that. You'll have to make your own I think! Nick  SignatureThe lowcost-DRO: <http://www.yadro.de> > A is 90 mm Ooops, sorry, wrong column: 75 mm! Nick SignatureThe lowcost-DRO: <http://www.yadro.de> >> A is 90 mm > > Ooops, sorry, wrong column: 75 mm! <G> Me again! I found a supplier selling pulleys for section A and SPA with an effective diameter of 55 mm -> <http://maedler.de/en/Catalog/P/1643/1617/309/311.aspx> Don't know wether they sell to the Brits. :-) At least their pages are in English.

Looks like the machine designers broke the rules. There appears to be a widely used modification of using a twistlock belt which possible gets acceptable performance from the drive. The machine has a 1.5hp motor which seems to break the other rule (from the back of my head someplace) of 1hp per a section belt.

I remember the last time I checked a Z belt for a large 24v 160A alternator and was surprised at what a Z could carry. Speed and pulley diameters obviously important. Check the Fenner or Gates site for "cogged raw edge" belts, you may find that Z would be ok and pulleys more easily available. Richard > The machine has a 1.5hp motor which seems to break the other rule (from > the back of my head someplace) of 1hp per a section belt. Forget that rule! The first limiting factor is the pulling force inside the belt (and thus torque). The second one is max. speed (in m/s; up to and above 100 m/s). So if you do have high RPM, you can transmit a higher power.

Thanks for that Julian, I've not come across them before. site bookmarked! Bob >> I'm looking for a source of A section steel pulleys 5/8" shaft 1x 55mm >> and 1 x 65mm.

Another recommendation for Bearingboys, just bought a couple of A section belts from them, ordered at 3.00pm and they landed on my desk the following morning ! |
