Maybe someone has some experience with something like this. I have a mild steel strip, .50 inches wide, .10 thick, with a thin PTFE material bonded to one side. This strip is pulled through two - three tooth broach cutters that trim a few thousandths off each side to width. The pulling is...
Yes, that configuration would provide the clearance. But the complications due to the length necessary would be about as bad as staying with a belt. I'm thinking that I should probably look a little bit at right angle gearheads, too. The ideal would be a longer motor, which might be hard...
My electrical supply couldn't come up with anything on this one. I found a 24V DC brushless, 100-2500 RPM, 1/25 HP, 15:1 gearmotor from Oriental. The great thing about it is the 20 mm distance of the output shaft centerline to the edge of the gearmotor. I'm trying to do away with a belt...
Well, it looks like Alpine Bearing may have some NHBB ABEC 7's. Yes, I am disappointed in my big-time nationwide distributor (who will remain nameless). It sure is nice to have a forum like this to go to where people know a thing or two.
I am looking for a source for extra precision ABEC-3, extra light single row ball bearings, specifically the equivalent of Fafnir M9102K. These bearings are available in angular contact, but I cannot use those. Distributors and Timken (which acquired Fafnir) have told me the M type is no...
After talking to our maintenance guys, I learned that they do routinely use tapping fluid while drilling and tapping polycarbonate here. At that point, we couldn't wait to try the brake cleaner test. We did and it was a real eye opener. Armed with this knowledge, I think we will have fewer...
I'm seeing what everybody is saying here about contact with liquids, and we do subject our usually 1/4" PC guards to a lot of liquids once on the floor in service in production areas. They do fall apart then in some cases. But I still see the material cracking a lot during initial...
Back in the 1970's when I first encountered Lexan polycarbonate, we used a lot of 1/8", 1/4" and 3/8" sheet to make machine guarding and enclosures. It was trmendously expensive then, but as I recall, virtually indestructable. We drilled, tapped, sawed, bent, heated, you name it, and I can't...
I'm trying to think of what the downside would be of just leaving the seals. You say the load is light, but don't say what the RPM's are. A seal is made of rubbery material and because there is contact, they generate a little heat, more at higher RPM's. If you don't have a heat problem...
I am looking for a cycle or hit counter to attach to forming dies. This counter would ideally be solid state, watch battery powered or maybe even unpowered, able to fit in a small space of a two inch cube or so, bulletproof, attachable with a couple of socket head screws and would count...
