Bearing info for Craftsman 10" Table Saw

[Kd4lok]

I am trying to replace the bearings on a 10" Craftsman table saw. The Nameplate ID is 103.23871. I have not found this number in the literature but find it similar to the 8" saw by ID 103.23831. I have disassembled the heart of the saw down to the shaft and inner bearing race, having removed the outer race and roller bearings. I am currently of the opinion that the bearing and shaft were manufactured as a unit. Please correct me if I am wrong on this.
If someone has replaced the bearing on their saw and can advise about parts that were used and are currently available, it will be appreciated. As well, if someone has updated their saw with a 5/8 shaft and bearing set, information on the parts used for this upgrade would also be appreciated. Thanks for your advice and help. Bob

Have you tried calling Sears Parts? With Sears in it's present state, it may, however be an exercise in futility.

Good luck

Thanks. I have not called but did look on the Sears Parts website. They have nuts and bolts items but did not find anything significant available for my saw that seems to have been introduced in the early 50's.

Check here http://vintagemachinery.org/home.aspx or take the bearings to a machine shop / bearing supply they may be able to read the numbers at the bearing supply . A machine shop can tell you they were most likely hot fit . And which bearings the trunion or motor bearings. ?

Can you provide some pics?

Bearings are quite standardized. If they're normal ball bearings, it won't be hard to find replacements.

This. Take some pictures, and measure the dimensions in millimeters. I can almost guarantee that they are metric.

Here is a link to you saw.

The bearings are not permanent to the drive shaft. You will have to be careful and remove them from the drive shaft. You can take them to a place that sells bearings and they will be able to match them up for you. The table saw you mentioned is the 8" version of the Craftsman Saw.

103.*** is the code for King Seeley.We are talking about something no newer than the 50s or 60s. I can almost gaurantee that it is not metric. As one who worked on equipment at that time, I can tell you that metric was practically unknown here. Except for a few imported cars of which there were few, we never saw it. Practically nobody sold metric tools or fasteners. This country manufactured almost all of it's own stuff and did not have to conform to a World standard.

Have to agree with FrankLee.

Many moons ago I changed the bearings in a Beaver saw CS 2200 and was surprised as hell to find metric bearings in a 40/50's saw.

Thanks for your comments. However, I just found a post on old-woodworking-tools.net from an owner who smashed the bearing and also determined that the shaft and inner race are in fact made as a unit. My current focus is to find an alternate shaft and bearings to fit the support bracket that takes a 30 mm od bearing. Bob

Is there a number or numbers on the bearing on the bearing? Excuse my skepticism but why would anybody build a bearing on a shaft? It is a lot of work for no advantage that I can see. It may well a very tight fit and maybe the shaft was frozen or the bearing heated. The fact that some woodworker, in the past, did not see the seam is not proof. There is always bad info going around.

Do a search at OWWM.org. I remember at least one King Seely made saw used a shaft with integral bearings. I think it was called a water pump shaft or possibly water pump bearings. Sorry, my memory is a little fuzzy on the correct term. If I remember right the unit is still available ( I don't think from Sears) but some machining is required.

You might be thinking of the Floating Drive. I've got an 8 inch table saw with that set up.
I suppose the work around would be to machine a shaft and press on the appropriate OD bearings.
Sounds like a great excuse to buy a lathe

I went and had a look using "Craftsman Water Pump Bearing" and got some hits though not for that exact model#. King Seely (103 prefix) and later Emerson (113 prefix) did use water pump bearings in some models of their saws. The bearings are basically machinable shafts with bearings that use the shaft as the inner race. You can still buy them but the ends will need to be machined to fit your application.

Might try joining oldwoodworkingmachines.com
someone over there should know 100% for sure.
They are strict though, may wanna read the rules also.
Like if you say in Passing, I may sell this saw when I am done fixing the bearings,
They will PM you and Say, That has to go in the classifieds.
But they are a knowledgeable group of guys.

I stand corrected. Live and learn. I still can't imagine why anyone would make it that way.
