Post up a detailed pic of each side of your bearing to compare to below.

The Dolmar 960-123-129 bearing sure looks OEM proprietary, with an odd casing on the outer face & no separate seal on the IPL, but I’ve never pulled a 4300 apart. Uses the failure prone nylon ball carrier too.

That’s it, not in stock and discontinued

Someone posted a link to a business that makes seals but I can’t find it. Bearings of this size are available, it’s the seals that I haven’t found. Are they proprietary?

here is a pic of the backside of the seal.

Here’s another pic showing both sides of the bearings. The seals have a spring by the way

They’re SKF bearings, I have emailed the company.

Are you looking these seals up somewhere, if so you could provide me the link and I can do it myself.

The bearings and seals are identical on both sides

I am looking for alternatives....Freunderberg company makes quality seals...

Regarding bearings.... SKF... ***.... INA.... it doesnt matter really!

 

[redhawk23]

SKF also makes seals. You’d think they made them for their own bearings!

 

[Tomos770]

But Dolmar didnt want them to be "SKF" way.....blame Dolmar!

 

[redhawk23]

I don’t know yet whether SKF makes the seals or not

 

[Tomos770]

Just measure the height of your seal!

Or even better....give us complete measures of your seals...

 

[redhawk23]

Seal thickness: Around 2.5 mm at the edge,

it’s easier to search for them once you know what they’re called: crank shaft seals or oil seals. Bearings have their own seals, apparently

Next Point Bearing
123 Bearing
Erie Tech Bearing

These places nay not help the OP but I know the builders are looking. Keeping them running helps keep us running.

Well....they made them non-standard on purpose......

Just sent a pic to SKF.

It looks like this is your part except your has a /C3 suffix which indicates internal clearance so the full part number would be ICOS-D1B01 TN9/C3.

ICOS-D1B01 TN9/C3

appears to be obsoleted and replaced with ICOS-D1B01 TN9/C3S0VP303. The S0 is a heat treatment that is stable to 150C vs 120C, which should not matter. VP303 means the seal is made from HNBR rubber and the part is packaged without any bearing preservative.
The good news is we do have them in stock. The problem is the parts are Italy and are not in the US system so we have never imported them here. The two options I see are going back to the saw’s OEM, or trying to find a distributor in Europe that sells these and will ship to the US.
This works for Europe as well, just zoom way out and then back in over there.

Great job in birddogging the bearings, hope you can source them without too much trouble & international postage...

Just remember to pull out the metal shield on the inside.
