Need help finding a bearing...

rtimgray · Jul 31, 2013

Looking for a bearing for my Kuhn mower, that is only available as part of a $300 assembly from Kuhn or John Deere dealers.

The bearing is a simple double-row ball bearing, sealed. Bore is 35 mm, outer diameter 72 mm, thickness is 33 mm. I have searched many, many websites, eBay, etc. and can't find it, except one place in the UK and they haven't returned my email about overseas shipping.

If anybody has any leads on this, I would sure appreciate it.

Thanks. Good luck and take care.

Not sure where you are located.In my area The company I use is Allied bearing.Many times I have gone in with a high 80 dollar dealer bearing and walked out with the same bearing at Allied
for about $14.00...I would look for a bearing shop or a company that supplies industrial companies in your area.
Good luck

ditto that. with id, od, thickness and roller profile, cone taper.. etc.. they should ( sometimes) match you up. same with seal....lip style, id, od, thickness...

So far I've always been able to find any bearing I needed from Purvis Bearing Service. But of course I don't know whether there's one close that you could take the old bearing to, to be matched.

I have used the online catalog of SKF many times to find bearings based on measurement or cross reference.

Bearings, units and housings - SKF.com/Products

Find a number this way and then cross reference.

I have tried our local bearing outlets, local farm store that has a huge inventory of bearings, and have a request in with a couple of our industrial suppliers (haven't heard from them yet). I have contacted both of the links given in this thread and neither of them have it - I did get a response back from the UK dealer and he is giving me a shipping price.

Other helpful notes: what I'm looking for should be equivalent to SNR GB12094-S04 or FAG 548083.

Thanks for the help so far.

I searched deeper at the site I posted and found this: 5207-2RS 5207-ZZ Radial Ball Bearing 35X72X27

Can you install a 6mm shim?

LD1 · Jul 31, 2013

A simple 5207 is pretty close. Right ID and OD, but only 27mm wide.

How are you measring the width?? does the bearing you have, have an extended inner race??

A 5307 is the right thickness but wrong od.

Are you sure it is a double row ball bearing and not a roller bearing??

Perhaps some pictures?

The SKF pages either come up as page not found or when I do get to a chart/search, they don't show one with a 35mm bore with the thickness required. Who knew this could be so tough?

Beat me to it:laughing:

I also found on MRC's website a 5207c1 and the c1 is extra width. But still only a tick over 30mm wide. And no greater load capacity.

Here's a pic of what's left of it - it had two rows of ball bearings. I also have what is left of the inside race. I'm measuring with digital calipers.

The fella on youtube that rebuilt his used a National 513002 bearing (not sealed), but the national 513002 bearing that I got doesn't fit - not even close. Don't know if there were some differences between years of manufacture - I know the JD dealer said that there were different parts breakdowns before and after some serial number breaks, so that may be one of them.

Thanks again for the help - surely someone will turn it over somewhere other than the UK.

I'd rather not have to install a shim if I don't have to - given that it's on a disc mower, and given the RPM that the blades spin at, I want as much bearing as I can get on there.

Thanks for the suggestion though.

Type SKF bearings in a search and it will come up. I have found lots of odd stuff there.

I can get to the SKF bearings page - but when I try to go to various pages within their site, it gives me the error. I even have an SKF number BA2 B445535 AE and I can't find it (all of these bearings show up as available from an overseas chinese importer, but not anywhere stateside).

Thanks.

Just got off of the phone with Allied bearing - they've got nothing, but they are (claiming) they are going to do some further research and get back to me. Looks like it may be coming from the UK after all.

There are two bearing shops not far from me. Either one can get pretty much anything. They do it for a living so they know exactly where to look and which suppliers to call if it's not listed. Do a yellow page search for bearing or power transmission.
