Hi, I have this pulley that is intended to drive a short length of steel cable back and forth. A picture of the pulley should be attached to this post. Alternatively, you may view it at photobucket here In this capacity, it had the cable attached to the pulley in the middle of the height of the pulley (bottom of the slot), and then had one side wrapped with cable, and the other side not. When it would rotate one way, it would unwind the cable that it had, and wind cable on the other side. I believe this is called a "wire rope pulley". After 20s of variations of that, a week on the calendar, and a couple of hours in front of the monitor, and various combinations with other words that I thought would be near to it, I did not turn up any relevant results in google. I've tried grainger, mcmastercarr, jlindustrial, smallparts, sdp-si, and a number of others that I found with google, and none of them seem to have what I'm looking for. Even a pseudo exhaustive inspection of all products listed on sdp-si's website did not turn up anything relevant. I called a number of places local to me, and most knew what I was talking about, one even told me the name as being "wire rope pulley", but none had what I was looking for, and the one that did have something close, it was somewhat larger than I was looking for (2"+ OD). This is not a conventional drive product (it cannot transfer single direction power continuously, where something such as a timing/cog pulley and belt can). I fear that these sorts of pulleys are all custom produced in large numbers and not available in standard configurations like cog pulleys and belts are. I suppose this is more of a motion control product, which, from what I can tell, is in short supply. For reference, the pulley is Aluminum, but I also have one like it that appears to be made out of GRP. It is probably metric, but using "inch" measure the bore is around 3/8", and the OD is maybe 3/2". What I am looking for is a pulley; Alum, GRP, or the like, that has an OD of around 1", and a bore of exactly 1/4" or 3/8". Any info or help that anyone can provide about this topic would be greatly appreciated. Thanks.
