Shopsmith Bandsaw Bearings

Post by backhertz »

In my on-going Shopsmith restoration, I'm still waiting on backorders: a couple of quadrant assys & a power cord. I am one double-bearing quill bearing short due to an Ebay seller listing one twice, when he only had one. So rather than pay to ship just one bearing, I took my band saw cover off & figured I'd get the bearing numbers so I can spread the shipping cost over several bearings. I'm a believer in replacing bearings rather than try to re-lubricate sealed bearings.

I took the wheels off. The upper wheel uses two needle bearing assemblies marked USA B INA SCE88. These are common.

The lower wheel has what looks to be an idler assy shaft. The markings are: 885144 A Japan OPC. I Googled it and found this is a common water pump assembly part.

The tensioner has two 627Z bearings which are one next to the other. These are common bearings, I believe.

The upper & lower guide bearings are marked SST WC77037-1. I was unable to find these on the net. I understand in the old bandsaws, these bearings were made of bronze. Anyone know of these?

There is another thread started by LDH, he posted a great set of plans to do an upgrade to the bearings. I have attached it again here. I have done it and it works great, I have lots of exta parts because I purchased items in bulk, PM me if you are interested.

Shopsmith Bandsaw Bearings

Post by billmayo »

The upper bandsaw wheel will accept GB88 bearing also. The upper and lower bearing guides will accept 77037 or WC87037 bearings. I get them from http://www.ebatmus.com for customers. The old bronze bearings just needed lubication when oiling the headstock. I remove the bronze bearings and use a good grade of wheel bearing grease. Never had any problems with my bandsaw in 28 years. I will continue to use the bronze bearings in my personal bandsaws.

bandsaw bearings

Post by eagleflight53 »

I could use a little help finding the bearings for my bandsaw; particularly the upper wheel needle bearings. I appreciate the help from this site.

Shopsmith Bandsaw Bearings

Post by billmayo »

I have been using 2 higher quality 627Z bearings at all 3 bandsaw bearing/bushing locations for customers. I had to use a very thin shim on the inside bearing on the upper and lower blade guide locations and file a small notch on the blade guides for the outside bearings to clear. I used the 514008 shoulder screw in all 3 locations. I will continue to use the bronze bushings on my personal bandsaws and lube them when I do the headstock.

I have ceramic guide blocks available for the Shopsmith bandsaw.

Blade guide assembly

Post by benjamin »

On the shopsmith bandsaw, is the blade guide that holds the bearings a die cast or machined part?

Problem is that this is a bearing/shaft assembly where the shaft is part of the bearing and Shopsmith appears to have molded the wheel on the shaft making it impossible to change just the bearing/shaft.

Or did someone find a way to remove the shaft from the wheel or bearings?

I think Nick once posted that he tried to remove this water-pump-type bearing with a 100 ton press, and it wouldn't budge....

I'm happy,happy,happy!

Today I put a 3 arm puller on my '59 Magna (Shopsmith) lower band saw wheel, and it easily :D started pushing out the shaft bearing assembly (New Departure 885126). Now I'm going to start looking for equivalent, or that 885144 A Japan OPC that was mentioned.

I thought I was doomed to start saving up for the $100 complete assembly.

Especially after I read:

Maybe Nick was trying it on a different year band saw?

...and Bill, I appreciate your insight on keeping the bronze bushed guide bearings. Will save me some money!
