The 2 bearings on my Logan lathe's variable speed drive are in need of replacement. I figured I could get them fairly affordably from one of the various bearing manufacturers, but I'm having a hell of a time identifying them. They do have a C-clip that is throwing me off.



There is one on each end of the variable drive shaft, under each of the brackets with 2 bolts.



Here is the shaft removed; you can see the bearings on each end.



This is driving me nuts. Is it a specialty one I should just order from Logan? They are $70/each from them. That seems a bit high to me compared to similar bearings I've replaced in the past. Parts direct from Logan do tend to be a bit on the high side.

ID: 0.984"
OD: 1.85"
Thickness: 0.47"

Try using the metric size, look up 25x47x12 with c clip, this should get you close.

We use a gazillion bearings at work, if SF doesn't give you the answer by Monday morning, I'm pretty certain my friend at work can tell you.

No real help. Good pix though. I would be in the camp to buy the factory ones. Then you know they fit and will most likely out live a generic version. mtcw

This one? https://www.ebay.com/itm/17486...tkp%3ABk9SR4LW-YiDYg

I hadn't considered metric. This is off a 1969 Logan lathe made in USA. I would have thought it was all standard.

Any numbers on the seal surface?, usually can look it up that way.

McMaster-Carr is another option.

Is there a specialty bearing supply house anywhere near you? That's your only hope other than ordering from the machine's manufacture, assuming they are still in business and have the part. That price, BTW, doesn't strike me as being all that high.

6005-2RSNR

SKF P/N 6005-2RSHNR
NSK P/N 6005DDUNR
Timken P/N 6005-2RS-NR
NTN P/N 6005LLUNR/2AS

All are Deep Groove Single Row Ball Bearings - C0 Medium Fit w/ 2 Contact Seals and a Snap Ring. You should check the existing bearing for markings to confirm fit, etc

The SKFs will probably cost $70, the rest about half that...The SKFs are probably worth it!

Should be a number on the seal. AS NHRA stated above. NR is for the snap ring. It has a rubber seal so the -2RS denotes (2) rubber seals. 6005 would be a 25mm bore size. Measure the OD and the width to confirm. All the listed brands above are good quality. They are all USA or Japan brands, just stay away from China made. Take the sample bearing to local Motion Industries branch and they can confirm the size for you.

That should be an easy lookup on a part number search and just put clip in the search too.
You can also do a search using the dimensions, ID, OD and length.

The clip is on any that also have a light thrust loading. Also specify a seal, metal would be best, since it's exposed to metal shavings.
Here's an example using the common bearing number 6202 (yours may be different):

I'd check to see if they were installed correctly in the last replacement or assembly.
I think the clip should be on opposite ends.

Rather than buying from Logan, I would follow the suggestions of the others and go to an industrial bearing supplier. Ask for the best they have. While more expensive, it will likely last the longest and run the smoothest. For accuracy on a lathe, you want the best available.

I can no longer read the numbers on the seal.

Lots of other great info; thanks everyone!

Take a look here. Lots of quality bearings.

Amazon has some Timken bearings at lower cost.

McMaster Carr was one of the first places I looked, but they didn't seem to have one with a ring in those dimensions.

Just do a search with the dimensions and you should find them easily.

The 6005 size is what he's looking for. All the bearings that I have ever used are specified in metric dimensions, even for U.S. made equipment. The OP measured them in inches, not mm. If they had been specified in metric measurement, they would have been easy to find.

We bought bearings by the hundreds, sometimes a thousand per order, for our rental equipment which was made in the U.S.A. (Reno, NV).

^^^Not that the math is hard, but the second post had the metric dimensions...

McMaster Carr shows two bearings with retaining rings and a 25MM ID, they have OD of 52 and 62 MM.
