My bad, I ordered the wrong size, so I never got to use these little guys. But they are good quality and the coating was perfect. Just wish I could read measurements more accurately, these things would have worked out perfectly.

this was exactly what i needed to swap my compressor motor over from a 5rib pulley design to a vbelt, to match the vbelt pulley that came on my replacement pump. appears to be balanced spinning at 3450 rpms on the motor shaft. good product, and shipped quickly. came with the locking screw to clamp down on the key. it did not come with a new slot key, but the old one fit perfectly, after buffing the rust off of everything.

I picked up a link belt for my vintage craftsman contractor saw, and replaced the stock pulleys with these. I was initially looking for a machined pulley, but the only ones I could find were outrageously expensive. Glad I found this, the casting is high quality. Between a pair of these pulleys and link belt the saw vibration is almost non-existent.

If you need a new pulley, which I did for my 1970 Craftsman Jointer. The jointer came with a similar pulley but it was cast iron and wasn't cast very well. Screw stripped and as much JB Weld I tried to put on the old one to make the screw stay it wasn't working. Ordered this pulley that has the same dimensions and when I got it. It was night and day difference in quality compared to original! Very very very well made. No doubt I can possibly strip the screw hole on this one. I'm very happy and impressed on the quality of this pulley.

Got a pair of these to replace the worn pulleys on a Sears Craftsman table saw circa 1975-1980.

On the good side, these are VERY nice, heavy duty pulleys. I have no doubt they'll last the rest of the life of the saw. They are solid and powder-coated. On the bad side, they're VERY precisely made, and on an older system you'll need to do a bit of work to get them to fit.

So... got some notes for you that might help.

1. Getting the old pulleys off required a blowtorch, penetrating oil, and a whole lot of cussing. The interior pulley especially took a while to get off since there was so little room to work in. (Being left-handed was a decided plus.) t wasn't quite rusted in place, but it was pretty close. The interior key piece took a lot of oil and hammer.screwdriver work to remove.

2. You WILL need to polish the shafts if you've got ANY sort of corrosion on them. These pulleys are very tight, and a thin coat of rust will mean the difference between it fitting and it not fitting. And even if you think they're clean, sand them down a bit anyway. (The pulleys ARE tight after all.)

3. You MAY need to sand the INSIDE of the pulley's hole. One had just a bit of overspray from the powder coating inside the center hole for the shaft. Guess what! It wouldn't fit onto the shaft until I sanded that out.

4. 150 grit sandpaper is your friend for both the shafts and the holes on the pulleys.

5. The key pieces, if they're removable, will likely need to be sanded down to remove rust and corrosion also. The interior pulley on my table saw had a key piece that had a very thin layer of oxidation on it - which was enough to keep the pulley from fitting.

Would I buy these again? Yes, very much so. The only caveat is that they're precise enough that they may be hard to install on older equipment.
