TB WoodsAK2558 FHP Bored-to-size V-Belt Sheave, A Belt Section, 1 Groove, 5/8" Bore, Cast Iron, 2.55" OD, 9810 max rpm

Exactly what I needed! Work like a million bucks. Keyway groove had to be delicately modified to accept a 5mm Key. Not the end of the world, Mic/file and done. Couple minutes in the vise and it's installed on the arbor, with Key and spinning smoothly under my new adjustable, segmented belt. The difference in vibration on my band saw is incredible. Bad pulley, plus old V belt to true, new pulley and new belt, the result of the effort, was extremely gratifying. Great pulley, .63 fit like a glove, on my .627 arbor.

Has a back spacing not indicated on the ad

The part seems to be well made. It fit the engine perfectly and works very well.

I bought two pulleys AK2558 to replace the aluminum ones in my Craftsman 113 table saw. (Product selection in this listing is for .63 inch bore and 2.55 outer diameter). My saw's original motor pulley was visibly bent and causing wild shaking of the belt and vibration of the whole machine as a result. Each pulley came in a cardboard box, with a light coat of oil on the machined bore, and minor traces of cardboard fibers stuck to the oiled surfaces. Easy to wipe off but I did feel that I needed to, not a problem. This pulley fit nicely on the clean 5/8 motor shaft and key with no slop, and turns with no visible issues. The set screw works as it should and the coating seems good, though I didn't try to scrape it so I don't really know. My saw now runs much smoother. I still have a small amount of belt shake, but I have not yet replaced the arbor pulley (will do that soon when I'm ready to replace the bearings). I'm happy with this product, it's a good value. One star off because it's supposed to be 2.55 inch outer diameter and measures more like 2.5 or slightly less. I don't know whether 2.55 is some kind of nominal dimension that doesn't physically exist, but I doubt it.

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.

My calipers measure the ID of the pulley as .624. Shaft is 5/8”. I’ll make this work by increasing bore and tapping it onto the motor shaft for a tight fit.This is a heavy part, much better made than the 30 year old Craftsman pulley. Heavy-Duty Grizzly motor due any day. I’ll mate them up and have a much better drive motor and pulley.

Well, it's a great product but It seems I ordered the wrong size. I don't understand why, in the United States of America, we tolerate the use of metric parts, even worse, mixed and matched SAE & metric parts. But alas, the engine shaft I have is metric and the pulley I ordered is SAE / Imperial.I measured the engine shaft at 12/16ths, but it seems to be a 20MM shaft because a a 12/16ths (.75) is just a hair too small. I'll put it in my parts box, I'm sure I have a motor or something around here with a .75 shaft that I'll inevitably use with it.The pulley itself is very strong, its well coated, but I'm very disappointed that its made in china. Its good quality though.Pity. Off to the hardware store.-2020/07/25 UpdateThe hardware stores don't sell metric parts! Even Amazon only has two suitable pulleys and they are very expensive; unacceptable!American ingenuity will not be hindered so easily! I took it to a family member who ground the bore diameter out to roughly 20mm and it now fits, if a bit tight. Since there is no keyway on the engine shaft, the keyway is irrelevant and the setscrew will be adequate for its intended use of powering a supply fan. Good steel quality, it took a little bit to grind it down.

Not much to say it’s a pulley
