Metric bearings in imperial wheel rims

Hmm, you're either a troll or you have absolutely no idea what you're talking about. Wheels mount onto a flange on a hub, in which is contained the wheel bearing. ...or I've missed something completely.

These are not car wheels, and from the size of the bearing i would have thought that was obvious. These are 8 inch diameter wheels for mounting on a small buggy. The bearings fit into the rims, and then onto a 17mm axle.

|Hi there, | |I am looking to buy the following from the usa | |

Your local bearing shop can get whatever you want, metric or imperial.

But not, as it appears, a bearing with an imperial OD of 1+3/8 and a metric ID of 17mm. Well at least not the company i tried to get bearings from anyway. Maybe i will have luck elsewhere, but was given the impression that this bearing would not be available anywhere.

Cheers

Mark

IIRC .075 mm or 3 thou is a very heavy drive fit. Google for "drive fit" "push fit", We used to have tables of such things, but I can not find them on Google.

Spin the hub in a lathe and ease out the 0.003" with emery. Alternatively, if it's not a high speed bearing or something under extreme load you can warm up the hub (If poss with a blowtorch) and press the bearing in.

I would ease the hub diameter out myself.

Take the extra bit of metal off the ID of the wheel so you can use standard bearings?

That'll teach me to speed read postings :-)

That sounds well within 'tap it gently with a hammer' range, or 'heat the housing with a blowlamp first'

You have missed the actual URL which shows an 8" split rim alloy wheel with integral bearing housings

So ream out the wheels...if you can't take off .075mm with a bit of emery you don't deserve to be posting in UK.d-i-y

I know absolutely nothing about metalwork, its not something i have ever had to do. (does this lack of knowledge in one area mean that i dont deserve to post here? its never stopped dimm and his dual combi bollocks)

Is it worth getting a sheet metal fabricators (i know one) to do this for me, or is it something that can be done by hand? I suppose i'll get the tinned reply, "if you have to ask then its best to get it done by a pro", but if not, do i need to buy any special tools to do this.

An old fashioned jobbing garage would be what you want - king pins etc had to be re-bushed at one time and they'd have adjustable reamers.

If you can get one bearing thats got slightly too much metal, then you can get two with the same ease. So take the metal off the easy-to-replace part, not off the hard to replace part.

Bearings are Hardened Steel and an absolute swine to machine.

Yes. Bearing shells are case hardened steel and most tools will bounce straight off. You need to hone them. Non trivial

Whereas mild steel alloy or bronze would be likely for the housings, and its easily cut or abraded.

Hi,

Why not buy the bearings from the US too, don't the above company supply them as an option?

cheers, Pete.
