rear axle bearing

[CSP311]

The bearing that goes on the rear axle shaft is 43215-08000, and doesn't have a built in seal, what is the part number for the same bearing with the seal built in? 43215-?

Cheers

Update, well looks like Nissan did superceed this bearing with a built in seal.

[Solex68]

Is there a different part number for the sealed version?

[CSP311]

Yep, and a different part number for the retaining collar too. It maybe not news to the roadster owners here, but it's new to me, and Wiki hasn't anything. Let me see what comes of the parts on order to see if this works out.

Nissan never changed the Roadster rear axle bearing and started to supply a sealed one in its place. There is no supersession. I found that sealed bearing 12 years ago from another vehicle and started to supply it instead of the 43215-08000 original in our product line. Nice find for me, sold tons. I have them in stock.
I buy them directly from Koyo 500 at a time with their internal Koyo part number, so the part number would be no good to you as they are not kept here in the states, nor will they keep them in stock overseas or sell them to private parties. There may be some lying around in somebodies warehouse here in the states if you my price is not attractive enough so search around.

Hello Dean, all.

Sorry the late reply, waiting for the collars to come in from the USA.

Dean, I have no problem with your $55 for the axle bearing, as like you and the other vendors are a wealth of knowledge and keeping our parts supply alive for our cars and in return make a living from it. I do have an issue with the cost of shipping and the Government import tax here in the UK (20% up to about $20, then another 20% over about $120), which is obviously out of the vendors or my control. E.g. to get one of your bearings to my door would be about $100, with the shipping and the tax. So, either I do a bulk order of parts, or find another source.

If I can source some parts here to lessen that, all the better. Bearings are a prime example, not being specific to a model of car, but more that the car manufacturer uses bearings mostly that are already available and design the car parts around that, it keeps their cost down. For example, bearings for the drivetrain and wheel bearings are generic, therefore a bearing that may fit a Nissan could well fit a Massey Ferguson tractor.

I didn’t say (43215-08000 ) was a superseded Roadster part, I said Nissan superseded THE part. The front (43215) part of the long Nissan part number IS the part, with the second being which model it goes on and minor supersedes (e.g. -14600 to -14601 where there is no visual difference and just a Nissan tweak). Anyway, what is more to the point, it the bearing is exactly the same apart from having a built in seal. The link below says its superseded, so I will go with that.

As Dean alluded to above, on his Koyo Bearing Cartel/Monopoly, I can’t comment on that, but since the UK isn’t a USA State, the Cartel doesn’t seem to apply here. It was easy to find the Koyo bearings in the UK, and the bearing supplier has 471 in stock. And as there are other bearing manufacturers and their bearing codes for these, I don’t think the Cartel covers these, so hopefully it will help someone. And by the looks of it Nissan didn't just use one bearing manufacturer either.

So, what I have found/common knowledge, is the 43215-0800 is 62mm external, 32mm internal (bore) and a width of 16mm. I just so happened to be browsing Yahoo auctions, and a seller was selling the stock roadster bearing and another, the same, but with a internally built in seal. A google of the part number, and what do you know…

43215-18000 Nissan part number for the bearing. It comes from some of the B110 models (Datsun 1200’s).

The site at the bottom says it is NLA, but also listed is the generic bearing codes. These are;

SKF GRW115R
KOYO 83294C4
NSK B32-3CC5
NSK B32-3AC5
NTN 6206BLUX/32C4

I brought KOYO 83294C4, for about £40 ($55) for the pair including shipping. These have the same dimensions as the original roadster axle bearing.

A very quick look on Ebay.com, shows one of the generic bearings for $9.99.

And this German Ebay; https://www.ebay.de/itm/DATSUN-B110-197 ... 4255641907

These here are NOS, and using the magnifier on the image, they are NSK B32-3CC5.

Also, the website shows a different part number for the axle bearing retaining collar. It looks different and is 43255-H1000. Whether it fits, I don’t know, but I followed up the link in the website (bottom) and brought a couple from RockAuto for $3.40 each. At that price, it’s worth a go. They measure about 41mm external, 31.7mm internal (bore) and 21mm width. As I haven’t done the bearing swap yet I am not fully in the know… Is the shape of the roadster collar 43084-10600 to hold the separate bearing oil seal in place (if using the 43215-0800 open bearing)? If so, is the –H1000 collar the way to go if using the -18000 bearing? Discuss…

Spacer, the roadster uses 43070-04101, which is superseded by 43070-01L00. The old Nissan part number for the spacer on the some of the Datsun 1200 is the same (-04101), but the number changed to 43070-H5000. Is the spacer the same? I am not saying it is, but if it works out as another alternative that fits, why not…

Whether this is all correct, I don't know, but it certainly could be a start.

Thanks for your efforts and your input.
Definitely helpful to the community here. By the way, can you explain your "'78 260Z"? I thought those were only made in 1974. Or was that just a US market thing?

[CSP311]

Thanks Todd for your kind words. I half expected a few more, but I understand how it is.

Yes, the UK and Europe got the 260z from late '73 to 1978 (though I had one first registered in 1980). Its a different beast than the North American market 260z, firmer suspension and sway bars, "aero package", and 5 speed (which we had for all Z's), no impact bumpers and I think the engine set-up delivered a bit more power too.

[CSP311]

Can some/all of this go in Wiki to help the community then?

[Steve_69]

Very good information. Definitely worthy of putting somewhere for future reference. Thanks.

I think the bearing information is good, but sure would not use any retaining collar other than the
Genuine Nissan roadster part.

Major safety issue with this!!

There have been serious accidents and totaled cars from losing bearing retainer press at highway speed.
At least one death as I recall.

The failures were likely not installed properly or an old retainer was re-used, but it’s definitely nothing to fool around with.
Buy new, correct bearing retainers. Anything else is penny wise/pound foolish.

Thank you for posting this information. It's really helpful, and good timing for me.
