Wheel bearing vs thrust bearing

Is there much if any difference between them? The reason I ask is that the bottom thrust bearing (and blocks) on my BS is/are missing. It still cuts, but doesn't track well .
To replace it does it require that specific bearing or will the same type bearings from the wheels work just fine?
This is just one of those mechanical things I'm not well schooled on.

I figured it's time to change my signature so hold your breath. This is it.
Impressive, huh?

Same type bearing will work fine.

If you don't have time to do it right the first time, when will you have time to do it over?

Thanks..I didn't want to use the wrong kind only to have things grinding apart whilst cutting things up..

Thrust bearing - Wikipedia

https://en.wikipedia.org/wiki/Thrust_bearing


A thrust bearing is a particular type of rotary bearing. Like other bearings they permit rotation between parts, but they are designed to support a predominately axial load.

I would get the specified bearing. Using a standard rotary bearing may work OK, on the other hand it may not. Depends upon the load it will be carrying.

For the most part if I have something that is broken or missing I try the normal and usual repair to get it back to operating condition. Rarely, if ever, do I look at re-engineering as a repair solution.

Bearings are not as uncommon as they look, most are dirt cheap till you get into high speed,big precision types.

For example $1.88 is a great price. This site has some of the best prices.
https://www.thebigbearingstore.com/r...ring-1-2-bore/

I built a light duty wood lathe last month and bearings cost less then $10.
Im sure some digging around and you can find the exact bearing you need.
The big bearing store site beats many other sites prices by a large margin.

By name, a "wheel bearing" and a "thrust bearing" are nothing alike.
The tapered roller bearing, or wheel bearing will take thrust loads, but it is not a thrust bearing.

Bearings are sold by part number ... not by where they are used.
This one is a Y32010X. Any bearing supply place should be able to get yours for you.

bandsdaw thrust bearings

There are two different positions that a sealed ball bearing would mount on the bandsaws height adjustment rod.

One is like this:


The other way is like this:


Neither of these are "wheel" bearings or "thrust" bearings as posted above. They are just typical ball bearings, which are sealed to prevent dust from entering. I have bandsaws which have it mounted in both those positions.

These are listed on Ebay as thrust bearings for a Delta 14" bandsaw:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

I don't quite understand this, is the complete unit missing or just the blocks and the bearing?

The same parts are used top and bottom, blocks are sold in sets of four, the bearing is a standard off the shelf product.

If the complete assembly is missing, depending on saw, one may be available on Ebay, on larger saws these are often upgraded with Carter Products for example.

the best advice would be to check the manufacturers parts list - what does it call out and use it. the band saws we have in house have the bearings perpendicular to the blade, and the part callout is the same for all - std ball bearing. no thrust bearings per se...

It's a used Ridgid 14".. I have no idea why the previous owner removed them.
There's a few other things missing as well. The blade guard by the post is gone as well..
Checking ereplacement parts has them listed as discontinued..go figure.
The guard I can work without even though I'd like it to be there. As long as I don't go trying to reach through there while it's running I should be ok..
The bearing and blocks bother me more..
I might rebuilt the whole thing when the weather cools down a bit. It gets a bit toasty by the garage door.

I figured it's time to change my signature so hold your breath. This is it.

I can attest to the Carter bandsaw guides, I replaced the ones on my Grizzly G055 and find the saw to be 100 percent better at cutting and tracking as well as way easier to adjust. If you have the money for the parts its the way to go.
