Ok let me see if more interest. They were engaged on LDU seal. Prefer not to disclose more without their permission. Anyway, their website shows Tesla logo haha. I'll be glad to share company name once I get more interest and their permission. One note is we don't know if quality will be better or ...

Maybe anyone can ask SKF about the dimensions of such an oil seal? It seems to be for electric motors, it would be interesting to know what sizes are available

From what I've read, Tesla seems to have no interest in selling parts to end-users (and few parts to professionals), which is discouraging. Yes, they sell engines and batteries only if they install them, but it seems to me that with the right to repair, the sale of the oil seal is really necessary,...

Probably yes
By the way, do you think it makes no sense to contact Tesla so that they start selling these oil seals or give the contact of the factory that made them

I can confirm my new Chenming seal is leaking. Sensor is wet after about 300 miles but doesn't seem to be leaking at a high volume. No fluid in the motor or inverter, and nothing came out of the drain bolt I drilled next to the sensor. The search for a better seal continues. @Boxster EV - Any updat...

Does anyone know the size of the O-ring on the drive unit speed sensor? I don't see the ring itself listed in the Tesla or MB parts diagrams. Mine was torn when removed. Edit - it appears to be a 24mm ID, 2mm thick O-ring. It is necessary that someone measure what was taken, try to approach the car...

johu: redacted excessive quote - please quote selectively

Is the red seal original or refurbished? And have you tried following the qr code on it?

What’s the point? It's all good feedback, Folks. The SKF 30x55x7 HMS5 V is designed to work with the SKF speedi sleeve 99114. If it works, it'll be a far easier solution to repair than having the rotor re-machined. I'm happy to be the guinea pig. I am however away on business for a week so wont be ...

I have now fitted the aforementioned SKF seal. It will run on the Speedi sleeve. I took the car for a blast last night and everything seems fine. I’ll update any relevant long term feedback in this thread. Edit: Johan kindly did some calculations ref RPM and seal tolerances. With my wheel sizes, th...

Maybe we just have to live with a bit of a leak and install a drain and 12V pump it back to the coolant reservoir (drill small hole next to reluctor wheel etc etc). Also check a good related thread on ENG-TIPS.com. From this thread (FWIW): "Bear in mind that PTFE is a sintered product, inheren...

There are people who make a new surface with the help of spraying. Yes: example of spray welding of tesla rotor on Youtube Yes, that's what I'm talking about. In order for the new seal to last longer, it is necessary that the surface of the rotor be in a normal state, and if there are grooves and i...

I’d be really interested to know if anyone has a lead on a good quality 30x55x8 seal. After a 1000 miles my drive unit is leaking again with Ceimin seal. And the one that dripped after 1000 soaps, is it still the same or was it 1000 miles, then a new oil seal and again after 1000 miles? And was the...

I think that most of SKF's PTFE seals are custom made to order. The closest SKF off-the-shelf catalogue seal that matches the desired dimensions and is able to run at 12,420RPM is the rubber(!) seal model HMS5 V , but that one is "designed for oil or grease lubricated applications" ( sour...

I got this response from them: "We do not sell to the public. Is this for personal use, or for a commercial application? How many pieces are you after? Please let me know and I can direct you from there." best regards, Aaron Friedmann It may be asked if there are those who sell their produ...

I also found such an oil seal on aliexpress, to the previously found ceimin

I think you should try to contact them or browse the catalogs of available oil seals on third-party sites.
You have given good information, thanks!

SKF does not offer a seal with dimensions 30 x 55 x 8mm (d1 x D x b, using SKF symbols). I just received this info from SKF USA by email. Hello, thanks a lot for the info. Who do you think we can turn to? After all, someone makes these seals for Tesla, it is unlikely that they themselves Ceimin sea...

How is your car and seal?

It’s no longer leaking with the speedi sleeve fitted. However I don’t think it will last long-term.

Hi ! How are you?

According to the seller, BK means "oil flooded" and should have a longer life. I don't know what they exactly mean with oil flooded. PTFE often has certain additives to improve friction and dry run, so maybe they mean an additive. Have a look here for the actual spec for the Ceimin seals ...

The Merc B250E uses a Tesla motor, and there are seal's available which you should be able to order/by from any Merc dealer. I can let you know the part number for each from the drawing below - let me know if any look close? Looks like they are £3-£10 so not expensive. https://live.staticflickr.com...
