  • Belt Grinder wheels?

    Will something like this work for wheels on a belt grinder?

    The bearings in those castors would never take the RPM of a belt grinder, that's my opinion anyway.

      No...

      Choose your bearings carefully - figure you need 3-4000 sfm for average use. Mine is variabe speed up to 6000sfm.

        automotive timing belt idler bearings make great belt grinder pulleys.

          On my "No Weld Grinder" 2x72, for the idler pulley I used 2 pulleys and the bushings from a Dodge Caravan 3.3 engine. Many pulleys will work. The reason i specified this engine, the pulleys are flat and the bushing has 10 MM ID. I mated the open sides it works very well. Also at the North Atlanta Pull A Part the Caravan is common. Check at your local self help salvage yard.

              No I doubt that a caster wheel will work unless it's slightly crowned. If it's not crowned the belt will fly right off it. The issue mentioned with the bearings is also correct. I think Mc Master has wheels for belt sanders, you might also try a company like Kalamazoo that makes belt sanders and see what they have for wheels that you can use.

                Are you wanting a contact wheel? I think Grizzly sells one that isn't serrated but that's pretty cheap.

                  Way out idler:

                  About ten years ago, I was given an old computer. How old? It still used those about 12 inch al. with copper flashing discs. Anyway, if any of you looked inside and found a 120 v ac drive motor, it is very smooth!! Mine has an Al. flywheel. Trouble is, not a lot of power. If you can get more more amps, good luck! With this motor, being so smooth, it could be the balancing motor because it is so well balanced! wayne.

                    As an FYI, if you didn't know:

                    Beaumont Metal Works sells KMG parts separately, including drive, idler, tracking, and contact wheels. They are not cheap, but they are (1) made in USA and (2) designed for this application.
