Bearing sources

Hey Guys!

Trying to track down some bearings for a Nelson .45 outboard, though not sure of the numbers and Google isn’t helping much with measurements.

From a set of digital calipers, the big bearing is reading:
OD: 30mm

ID: 19mm

Depth: 6.3
And the small:
OD: 22mm

ID: 9.5

Depth: 5.5.

Preferably a high quality ceramic if possible, but open to a source either way! Thanks!

You might try Jon Thibodeau at [email protected], he's on this forum and has been my source for WIB bearings for everything except the Novarossi special bearings, and great to work with.

Alan Elzer ran Nelson motors, he might know a source and size?

Try Boca?
They've come thru for me on hard to source stuff...

Hey Mike!
Unfortunately I think those might be for either the short stroke Nelson or the long stroke, small crank. I’m assuming these calipers may be off a tick since the sizes aren’t ringing up exactly standard.

Frank,
Tried using the boca bearing search but hasn’t been completely helpful. Will probably need to try and give them a ring instead

I will shoot Alan a message Brad, don’t know why I didn’t think of that

Thanks for Jon’s email! Didn’t have it, I will shoot him a message as well.

Brandon,
Those odd ball sizes for bearings would lead me to believe that you are looking for something sized in inches.

Check and see if they size out at 1.1875x.750x.250 and .875x.375x.218.

Try calling 336-685-4000

This guy sells the Nelson airplane engines. Maybe he can help

So yes! Figured that out with the Large Bottom bearing, I will have to double check the top bearing because I couldn’t get the numbers to work out properly, unless the calipers came in that far off.

Are those sizes you’re able to get Mike?

Thanks Fred! I’ll give them a ring

Sorry Brandon, I don't have those bearings. Your best bet is to look them up on Boca bearing site.

Hey Brandon,
Try ACER RACING on their web site.

Thanks Mike B.!
Double checked the sizing, pretty surprised to see Imperial measurements used inside of an engine!

Bearings tracked down

Interestingly, the PTO still uses the 698 bearings

If the small bearing is the .875x.375x.218 size, that is a version of an R6 bearing. I looked in some stuff the other night and I have a couple of them. You can have them if they fit. I have no use for them.

R6, that was an OPS 67 bearing

Yes those will fit, just let me know what I owe you!
Much appreciated!

looking at the 698 on Bocas Website there are so many different kinds. What would be the best one for PTO? I’m looking for the 698 as well.

You can get all your bearing needs from Technology hobbies

Just send me your address. We're good unless you'd like to come up here and shovel snow for me today.

I can send some pics of sunshine from Florida instead?

Lol, shooting you a PM now. Thanks!
