Hi people, I have this old saw now for 40 years and love it. I must rebuild the head track and the 4 bearing/wheels that controls the head in and out. You can buy the two small tracks that head rides on, but You can’t buy the wheels/bearings anymore! Has anyone else run into this problem? Any info would be great.

What model saw? Searspartsdirect, ereplacementparts and several other have them in stock, at least for my c-man RAS which is about 40 years old; although they are way expensive. Got a part number? Also, you might be able to rebuild those bearings unless they are very bad off.

Cheers,
Brad

Try eBay for the bearings. There are a lot of Craftsman RAS out there and are always being parted out. If I were you, I look around on Craigslist for a Dewalt or multiplex…much better saws and cheap.

I’m not familiar with those bearings, it’s possible they may still be a stock item (bearing supplier, take one with you), or not. E bay does have some stuff from parted saws. Are you sure they need replacing? I’ve rebuilt 4-5 Dewalt saws, and only had to replace 2 bearings. The others came to life after being soaked in solvent and “spun” a little.

Normally, most bearings are a stock item Fred.. but, at least for my C-man RAS, those are weird ones:

Kind of need to know what model saw the OP has though to make sure. Also, I’d be suspicious of any bearing that has been soaked in a solvent without re-packing with grease after. You wind up with metal on metal which won’t last very long. For sealed bearings, it’s pretty easy to pry off the seals, soak and clean and then re-pack them, and I’ve done that quite a few times before with great success. Shielded bearings can be done as well, but much more difficult to get the shields off without damaging them. For those, many people have had good results by ‘canning’ them without the need to remove the shields.

Cheers,
Brad

Maybe its time to retire it. Have you thought about a sliding miter saw?

You will need to know the model of your saw and preferably the numbers on your bearings and some pictures. But if you post over at OWWN.org those guys should be able to give you some good direction.

Good luck.

It’s not a problem to clean them, ask any of the guys over at OWWM about it. I think that’s true in powered/heavy load usage, but the bearing on a RAS carriage go back and forth very slowly, and have a fixed load that really isn’t all that much. I have cleaned and replaced the carriage bearings on both my RAS, and one has been in use for over 7 years with nary a squeak. No doubt, if his bearings are as in that pic you posted, they won’t be a stock item.

Got ya.. had the impression you were talking about bearings in general since there are more than just the carriage bearings on the RAS. I agree that for those, it’s probably not much of a concern.

I bought a Craftsman RAS back in late 70’s. My first “big” woodworking tool purchase. It’s mainly used for crosscuts now. I occasionally clean the tracks and wipe bearings, but have not noticed any issues. Would be interested in knowing if and where you do find replacements…just in case!

Out of curiosity, I did a search and found this…

Kinda pricey, but looks like you can still buy. Saw some on eBay too, but that’s a gamble.

Most appear to still be available from Sears, but as noticed, you pay out the nose for them (they want over $50 a piece for the ones on my RAS!!!).. If the dimensions can be measured, you can get them from most bearing suppliers for a fraction of the cost. They are typically referred to as U-groove, U-channel, V-groove, pulley groove, rail channel or a couple of other names along those lines depending on the manufacturer. Small ones like used on the RAS shouldn’t be more than around $5-$10 a piece.

Cheers,
Brad
