Hi Darren,

Yup….couple of reasons for that….
One is, a cam follower has a lot more stuft. Eccentric haft, bearing and housing, and the bearing is a needle type.
Other is, they just don’t make that many, in comparison to something like the ball bearings used on my Grizz saw. (6000-2RS) They pump out a kazillion a year. Cam follower….not even close.
And they are, a heavy duty bearing. Have to be to take the loads they are designed for.
Stainless? I wouldn’t bother, or even think about it.

As far as the drive & idler wheels….I would doubt the bearings in those would be anything exotic. All things considered, not really a lot of load, compared to a lot of things I have worked on, and the RPM is quite low. Besides that, impact is pretty much non-existent.
You will find out when you get in there, but I doubt it’ll be a big deal! I’d thing they are either ball or deep groove ball. Needle bearings would be overkill.
Whatever you find in there, I would replace them by what they are, by part number & configuration. (seals, shields etc)
My opinion, for something like that, stick with name brand bearings, ie; SKF, Timken, NTN, etc. You can save a bunch of money by going through someone like VXB, who sells made in China who knows what they are bearings (they do sell some name brand stuff) but why?

When you get to coolant systems, speak up. FYI, I use none on my saw, unless I cut hardened alloys, like 4140/4142Q&T or something, or thick steel parts. And I use mist, rather than flood when I do. For most things around the home & for the hobbyist, flood is overkill, and somewhat messy, in my opinion.

Fun project you are on Darren!
Look forward to hearing more!
Bill

Bill,
You weren't kidding. They are PROUD of those cam followers. However, I believe I have the proper size ordered. We'll see in a couple of weeks, once they arrive from the manufacturer. I plan on implementing a liquid lubrication system, at some point. I looked into the stainless steel cam followers but decided against them as they literally cost more than silver, per ounce. So, I got the sealed version.
During this experience I started looking at replacement drive and idler wheel bearings.. I figured I'd probably need just regular bearings. However, after learning about the loads these things put on the blade, I have to wonder, that load must be transferred to the bearings. Right? So, should I be looking at any particular bearings for the drive/idler wheels?
Thanks for the continued support!
Darren

Just needs a bit of TLC!
All the saws I have seen that used cam follower guides were high quality US made machines. I remember a DoAll we had that was built that way.

Bill,
I appreciate your positive outlook. :) It's been an education thus far. I.e. concentric vs eccentric. ;). I continue to learn from y'all and appreciate every bit of it! For my own knowledge, and anyone else who might look for this in the future, I'll post up what I find.
Thanks again!
Darren

I’d bet they are standard flavor, that you can find easily at a bearing house, or online...
Good news is, they are a far better bearing than a ball or deep groove ball, and will last a lot longer.
Smaller ones are needle, larger generally a double row needle, and will handle a lot more load than ball bearings.
They cost more, initially, but overall, the cost will be less due to the long life they have.
I’m thinking you will have a really good saw when you get it all plus’d back up!

Dang, I was REALLY hoping that wasn't the case. Wanna bet these are funky dimensions? Time to get out the calipers.
Thanks Bill!
Happy Thanksgiving to all that celebrate it tomorrow! :)

You don’t replace just the bearing, you replace the bearing, stud & all.

[Attachment(s) from Darren McCarley included below]
The resurrection of the Bainbridge bandsaw continues.. I've refinished the stand and base. Moving on to replacing all the bearings I find myself a bit bewildered. Attached you'll find images of the guide bearings. I believe the bearings are captured by the concentrics. However, one bearing shows signs of a previous owner trying to press the bearings out, and failed. So, I don't think I'll be attempting that route. I doubt the images show it, but I believe I see threads under the concentrics. However, the bolt is pretty soft and I don't want to screw up the flat head.
So, my query to this group, how the heck do I go about getting these trashed bearings off???
I've considered they may be reverse threaded. However, I come to the same conclusion, regardless of the direction, I don't want to scar the concentrics. They are about as thick as a Sharpie pen and rather thin walled.

Thoughts? Suggestions?
Thanks
Darren
