Rear Hub Bearing part number?

[rfurzer]

I have done a search here on non-gen replacements for the bearing 07296 (or 270604) and popped off to my local bearing bloke for a nice high quality (ie not britpart) bearing. I had SKF or FKC 88128 as the number.

I was then asked 88128-R, -RA or -RB?

which one is it?

Thanks

Hi Russ

Ive just fitted new brgs on Klonks rear axels, have checked the invoice and no letters after the part nos. The brg company said they were the ones used in Ford F150 rear axels, so figured they would be fine for a land rover. Sorry dont have the packet now.

I removed the inner bearing seal when fitting and half filled the space between bearing and seal with bearing grease as there is not much in the bearing, dont fill the space,this allows for expansion when hot.

R & RB are listed here. TIMKEN BEARING part number system (nomenclature) (http://www.ahrinternational.com/TIMKEN_nomenclature.shtml)

Did the bearing bloke explain what the letters stood for or was he just looking through a bearing catalogue and didn't know himself ?

colin - the latter

Thanks for the link. Unfortunately I dont understand the difference even when spelled out in the attachment.

I have been offered some old stock bearings labelled for S1 Land rover rear bearing use that are 88124 rather than 88128.

Soooo confusing.

Furthermore, the F100/ F150 ones (said to be the same) have at least three variations on 88128 including R, RA and RB. There are some F100/150s that use a different size item too.

If I remember I'll see what I used when I did mine 3/4 years ago. I think I still have the box and the old bearing somewhere.
I just took the bearing in and got them to match it.

The R & RB don't sound right but, yes, it isn't clear in the description.


Can't find 88124 via the internet.

Another part number shows up here 514003 as a replacement for the 88128 (probably a Ford number)

Just to confuse things. Ive been told the 1950's Grey fergy tractor uses the same wheel bearings

The ones I fitted were 88128R.

I left both seals in place because the grease used during factory assembly should last the life of the bearing.

The ones I removed had blistered rubber seals due to the brakes being partly jammed on ! Still well lubricated and I only changed them 'just in case'.

Grey Fergie seems to use taper rollers but perhaps they changed at some point ?

This is one I removed from a S1 semi floating half shaft.According to my bearing catalogue, 88128 and 407592 are of identical dimensions.Seals on both sides. L/R no 07296 . Maybe the number changed, when the seals changed from metal to "rubber". .W.

Called in to the brg company we use at work while getting other parts. Asked about the letters, and was told that they usually refer to types of seals, corner radiases on the bearing and circlip grooves. He was abit busy to look up the exact listing.
Also he said a third to a half of the capacity inside the wheel brg is ok to fill with grease.

At work we run five road trains from Albany to the Pilbarra, all the hubs are half full of grease and we've never lost a wheel (touch wood). The company next door also run trucks, they only used to pack the brg and leave the hub empty. They lost ten Wheels last year. (two tyres,two rims and a brakedrum = one wheel x 90 kph).
Thats alot of death and destruction if you get hit doesnt matter what size vehicle you are in. They have now changed that.

Just something to think about next time you see a truck and trailer comming towards you.

If you overpack a bearing with grease you get 'churning' which causes heat.
I've always wondered about those trailer hubcaps with grease nipples and can imagine people pumping grease in until it forces out past the seal !

Yes your right :o

Back in 1979, a friend and me were driving between Ballarat and Creswick . A large truck appeared - coming towards us . Anyway , when the truck was about 150 metres away, a rear wheel came off the truck, the wheel was headed straight for us :confused:

You can imagine our shock , what to do.

As the wheel got closer, it veered onto the road verge , right in front of us , across our path - it then careered off wildly into the bush .

I have a confession,the only reason I removed the bearing seal was because I damaged it while fitting.:oops2:
I removed it to straighten it and noticed that there was very little grease, so had to change tac.

Colin. I have those hubs on my boat trailer and I don't grease them much as you stated.

Mike, Bet you have to change the seat as well as your trousers.

Did anyone ever come up with a final set of alternatives for this bearing? Several different possibilities are tossed about but no one every posted any conclusions. Just curious.

[gromit]

88128R fitted my '56 Series I OK.......the alternative letters after '88128' determine whether there are rubber seals a chip shield or no seal.

I chose the sealed ones (R).
