bearing makes.

[EML]

Changing the tyres for Double the Dirt this week end today and have found the bearings need doing again!! Every time I cahnge tyres it seems I need to do bearings-does this happen to everyone or are my suppliers giving me shite products?

[LWC82PE]

Change to SKF, they have the best seals by far and last way longer than NTN, Nachi, Koyo etc.

eml sidecars are harsh on wheel bearings unless they are upside down

Quite often the tube that sits between the bearings in the hub gets crushed over time.
The outer race of the bearing sits up against the lip in the hub so if the tube is too short then the inner race is under too much sideways pressure.

Doesn’t matter what quality bearing you have, they will all fail under these circumstances.

Either buya new one or machine one up.
Measure between the outer edge of the lips in the hub to determine what length the tube needs to be.
I usually make them between 0.25 - .035 mm longer than what I measure to make sure the balls is not under any thrust pressure.

Yes and hello Mr GMC. I know that the tolerances can be critical in that area and those tubes should be changed from time to time.
The thing with the sidecar is that it spends alot of its life going sideways so maybe this has a bit to do with it.
I also know that you have to keep the wheels rolling after jumps or they will cop a caining too, however I expect to get more than a couple of meetings out of them despite all the bumps and jumps.
Time for a brand change as LWC says.

[GMC]

Certain bearing sizes are available in what they used to call transmission bearings.
Basically they had an extra ball in them and could cope with more loads.
Try counting the balls in the bearings that are failing and compare that to what is available.

[EML]

Thanks GMC, will try that.

[Lozza]

Try cylindrical roller they locate the shaft better axialy.

[Freakshow]

Try counting your balls in the bearings.

Yer EML.......  count your balls buddy   

[EML]

That's what I did after Popeye and I went upside-down

[LWC82PE]

EML, we found that on 16" sidecar wheels which have the bearings more exposed to the elements that SKF had the better seals to seal out the muck and water. Other brands such has NTN had crap seals and needed replacing after 1 wet muddy event. Then changed to SKF and they have lasted several years/several seasons. The seals are just so much better at at sealing out the mud, dirt, water and you can actually see the seals are better quality and a tighter fit.

lcw82pe you seem too knowledgable about sidecars methinks you need too find one and bring it out and play
