MG Midget and Sprite Technical - Taper bearings (Q for turbo bob)

http://www2.mgcars.org.uk/cgi-bin/gen5?runprog=mgbbs&mode=archiveth&archiveyear=110_2009.dat&subject=110&subjectar=110&source=T&thread=2009022409303630996

Did you get anywhere with finding a good price for these, I'm about to strip the hub for another reason and thought now would be a good time to invest
Will Munns

Will, from what I've experienced with the conversion you should be able to source the bearings by size just by measuring your original ball type races for width, bore, and diameter. The real key is the radius on the inner bearings inner race, it must be large enough to clear the fillet between the stub axle and the kingpin. I couldn't find a bearing here in the US that would fit after checking with several bearing suppliers, so modified mine with a die grinder. Worked great and now fits up fine.

Are you asking Rob ((Robert)Turbo) about the 40deg face-adjusted bearings?

Anthony Cutler

Yup, at the end of the thread he was still investigating cheaper sourcing
Will Munns

If you re-visit the thread, I think someone had found a good price, (i.e. much cheaper then I paid!).

But as a comparison, bearings for a MX5 are twice as dear as the worst price I could find for these 40" degree bearings. And it's a good conversion too.

I didn't se the cheaper price, are you sure they are the ones Bob was refering too...?
I too am waiting to order at least one set of Bobs 40 Degree bearings.

count me in on any info, part numbers etc.

I'd like a set too please.

At the moment Will I have not been successful in finding a cheap supply. I suppose you get only what you pay for. What we need is someone who has an account with either NSK or SKF then we could deal but I have not found anyone as yet.

However I think if you bargain hard with the suppliers then you should be able to buy 4 bearings for about 90 quid which isn't too bad for a superb product that does what you want it to do.

Here is the better link

If you go into a bearing supplier make sure they give you exactly the right bearings as numbered in the article and get a price on both SKF or NSK as they do vary.

Will,
got mine for just about the 90 quid mark inc vat, if you have no joy your end I will get you a set and post them, if thats any help!

Howie,
Did you get your bearings from a supplier in Cambridge?

I tried to get these 40deg bearings yesterday, but the price for one side was about £80 and would have to be ordered from aboard!

where is a good company to buy from?
d cusworth

looking in my SKF manual, the BECB means "angular contact ball bearings single row for paired mounting"
all drawings show a pair of bearings together.

on another page there are bearings with the page headed "angular contact ball bearings single row"

would these be cheaper and more suitable?
d cusworth

All bearings are mostly ordered from abroad, vast majority are made either in china or Japan. :-))

Obviously your supplier does not work very hard to get what people want at a fair price

With regard to your question about single row usage the whole point about why run of the mill bearings do not work correctly and end up with play is because the Spridget design is for 2 bearings and thus it require 2 bearings that are machined to suit each other

Have you read why?

http://www.mgcars.org.uk/mgcc/midgetreg/Frontwheelbearings.shtml

If you don't agree with this I would be very interested in your thoughts, please
Robert (Bob) Midget Turbo

Still 90 quid for BOTH sides SKF 7303BECBP X 2 & 7205BECBP X 2

Best Regards,

Howie.
Howard Wright

The cheaper bearings could be used but you would have to use shims to get the preload/clearance right when used with the spacer. I suppose as people do use taper roller bearings without the spacer the same could be done with angular contact bearings and the nut adjusted to give the correct setting.
David Billington

howard - is that "still" 90 if we get them from you, or "still" 90 if I go to the right place?
Will Munns

Robert, I have no experience to go on, and admit i don't know what i am talking about, but the BECB bearings are illustrated running in a matched pair in different configs

http://www.skf.com/skf/productcatalogue/jsp/viewers/productTableViewer.jsp?&lang=en&tableName=1_3_2&presentationType=3&startnum=2

if you drop the "CB" off the part number (ie 7303BEP)you get a similar bearing designed to work without an identical bearing next to it.

it's too late for me as i had to fit something in time for the weekend, so it was the best standard Chinese bearings for me, which actually fitted better than the last set 17 years ago!
d cusworth

Of course David is correct

The non face adjusted 40 degree bearings can be used as a taper bearing with no spacer fitted but with the nut adjusted correctly and locked into postion. I spoke to NSK about this application and they agreed that was possible although the more expensive face adjusted bearings fitted as designed originally would give better reliability and durability.
Robert (Bob) Midget Turbo

Will,
I will get you a set for 90 quid + postage, I have a mate at the supplier, this is the same for anybody interested. Let me know
Howard Wright

Robert,

Hopefully that wasn't meant as though I was always correct, as I'm not, although I do try to comment on subjects I have knowledge of and not when I don't. I'm not a bearing expert by any means but can see that the face adjusted ones are appropriate for the standard application whereas standard bearings don't have the requirement on the face alignment and so might require shimming or adjustment. The fact that the bearing inner races are clamped in the standard application may also help hold the inner races in better alignment than if they floated slightly, have seen many worn stub axles mainly outer ends with adjustable arrangements.

I would love to hear from enthusiasts who have fitted these bearings and found them to fit correctly and remove the play associated with cheap alternatives.

I have fitted them successfully and hope others have too.
Robert (Bob) Midget Turbo

I will nudge my bearing supplier, I was with him last week talking about these bearings again. Like bob, I believe these to be probably the ultimate set up. has anyone bought a set of Std Spridget ones off the shelf recently? They are absolute rubbish!

Mark.
M T Boldry

I agree!!
I replaced the kingpin/stub axle set up less than 800 miles ago and renewed (standard) bearings both sides, 1 set went in with a touch of play, the other with none. MOT last week and he pointed out that there was play on each., roughly what was on the ones they replaced

1st happy customer,

Howard Wright

I was chatting with Paul at PBW last week, he agrees that most bearings now available are rubbish too.

He says he can get better ones if I want them but frankly I am tempted towards these too. I'll see whether I get an MOT this week, (slight rocking detected, F.O/S)

we shall see

These are SKF and made in Austria, just installing mine in my nice new alloy hubs.
