Topic tags/keywords: bandsaw question bearing 422291390002 delta 28-190 thrust

Hi all -

I snagged a pretty cherry bandsaw at auction for $40, and when I was swapping out the old dull blade for a new one, I noticed that the previous owner had lubed the thrust bearings with automotive grease. So basically, they are now glued still.

The lower bearing had actually be cut almost in half by the back side of the blade.

Looking up the part (422291390002) gives me prices around $28 EACH. For a single bearing. Insane.

These look an awful lot like a roller blade bearing to me. So the question is, has anyone substituted a non-oem part in for a roller bearing with any success? Are these just rollerskate bearings with insane prices? Are there any aftermarket thrust bearing assembly replacements I should look at?

Thanks for the info!

Personally, I’d buy the exact right bearing. You already got a deal on the bandsaw, and 56$ isn’t all that much money if it gives you years of service.

Take it down to the local bearing shop. They can match just about anything. I have one called Motion Industries about a block away. Most larger towns have a source for stuff like that.

I’m all for buying the right ones. I was just wondering if anyone knew any secrets about the topic. For all I know, a Bandsaw thrust bearing is the exact same thing I have on my skates. I’ll pay the money if I have to, but if I don’t have to, I don’t want to. Knowhutimean?

I also would take it down to the local bearing shop or perhaps an auto supply. They’re spec’d out as I.D. O.D. TH which is inside diameter. outside diameter, and thickness. If you can get the bearing # off of the back of the bearing you could order it off the ‘net.

I found I have a couple of those Motion Industries places around. I’ll pull one off, clean it up and see what I can do.

Most good bearings have a part number thermostatically etched in one of the races. Match the number and double check the ID, OD, & thickness. When I rebuilt my old Rockwell 14” BS, I saved about 75% on what Rockler and the other stores asked for by going to a bearing dealer. I used King Bearing here in California. But they have changed their name once or twice since I’ve dealt with them.

Try to save the SKF number when you clean them. Any thing in Timken is good.

I’ve heard rumor that people HAVE replaced their bearings with ABEC-7 or ABEC-9 bearings, and with great results.

I don’t KNOW THIS AS FACT, but … one day … I’ll take the micrometer to my OEM bearings, and … if they fit … they fit.

Is there any reason that logic sounds flawed to anybody ????

I Rollerblade. I do NOT believe that ceramics, or ABEC-9’s will equate to an extra HP on my Grizzly (LOL), but … they’d STILL be cheaper than any OEM stuff … likely.

This isn’t a swap, but .. this guy is a well known woodworker, and he’s making it work.

I’m gonna’ look some more. I want my Grizzly to FLY :-)

Here’s one of our own that made it work on his Rikon:

Another—less certain—data point:

More anecdotal info here:

I THINK this is LJ’s own knotscott:

If I were a betting man, I’d say most Taiwanese 14” band saws WOULD take inline skate bearings.


Will YOU be the guinea pig ?? LOL!

When my Carter bearings froze up, I just took them down to the local auto parts store. They had two quality level bearings to replace it, so I chose the more expensive. I don’t recall the details of the bearing, but they work great. I don’t think the thrust bearing its a hyper-critical application. After all, the saw seemed to function with one nearing completely frozen. Anything you do can only make it better.

Iturra Designs 904-642-2802 they sell thrust bearing for $15 and have a wealth of knowledge. They say they are going to put up a website soon, we will see.

Have your say...
