Hi all,

I have a small 9” Delta bandsaw (28-150) that was given to me. I was able to use it to make a few inaccurate cuts before realizing it needed a lot of TLC to be usable. (and after it kinked a brand new blade I got for it.) I found new tires available on amazon, and I’m trying to find how I can replace the Thrust Bearings. I know how to get the shaft out of the guide, but I can’t tell how to get the bearings off without doing damage. I’d really appreciate it if anyone can tell me how to get the tiny clip off of them?

That bearing is very small; 9/16” in diameter. I’d like to get this little one running to tide me over until I get more power run to my shop (aka garage), and buy a larger one. If you know a good place to buy new bearings that would be great as well. The guys at my local hardware stores look at me like I’m speaking Greek when I ask if they carry thrust bearings.

Thanks,
Jon / Vaul

There is a retaining clip (circlip, snap ring, what ever you want to call it) that holds the bearing on. Remove the clip and the bearing should pop right off. I don’t know what size those bearings are, but on the Delta 14”, they are just standard 6200ZZ bearings that can be obtained anywhere.

Cheers,
Brad

Edit: After a little digging, it looks like those are 696ZZ bearings, OD 15mm, ID 6mm and Width of 5mm. Measure to make sure that is what you got.

Yeah, I’m wondering HOW to get the clip off :) I tried pulling/pushing at it with my tools but it doesnt seem to want to move enough, and I’m afraid I’m going to bend/break it.

I’ve never seen such a retaining clip, unique looking – also it appears to be partially “sprung”, but should be serviceable.
But in any event, you can use a pair of circlip pliers or even smaller pointy needle nose pliers to spread it apart and remove it, but keep your thumb over the end of that shaft as you remove the clip or you’ll be chasing it around the shop.

There is a special tool to remove and install that snap ring. Look for a “snap ring tool”

You can get a set of circlip pliers (internal and external) at HF for under $10 or can find them at any hardware or big box store. Alternatively, you can usually get them off with a small screwdriver and a pair of needle nose pliers. It needs to be expanded (using the two holes) so it slips off the groove on the shaft.

Cheers,
Brad

PS: If you DO break the clip, you can get them for a few pennies at the hardware store.

After you get the snap ring off gently put pressure on the back side with a screw drive while you tap the shaft with a hammer. Bearings are easily obtained at a decent auto parts store. I just went thru this process with my 50 year old band saw.

While that bearing may be acting as a thrust bearing, it’s really just a roller bearing being used as a thrust bearing. If you look at a source for bearings, you probably won’t find a match under “thrust bearings”.

I usually get bearings from VXB, although there are many sources. If the one you have isn’t marked (something like MrUnix described), measure the ID, OD, and width (use calipers, and it’s probably metric), and they should have a replacement.
