I have question regarding bearings - how often and how do you clean them?
Which lube or grease do you use? (I have some b*ke chain lube and Shimano green grease).
My enviroment is dry but with lots of sand and dust.
Bearings (QuAx alumuni 26") with dust seals and they are in sand. I cleaning them but it feels that they moving much harder then before. It seems to me that I will not be able to install dust seals back if remove them.
take your wheel off and using a stanley knife or other fine tip blade prise out the dust seal from the outside edge, then using some nice thick grease repack them and push the seals back in so they sit under the lip of the inner and outer bearing race. For a proper job use a bearing puller to remove them from the axle and take both seals off degrease the bearing and repack with grease and refit. However it is easier to junk and fit new ones which are cheap as chips. If your bearings feel like crap the damage may have already been done.
The bearings are not made to last offroad with dust seals rather than bike hubs which have labrynth seals. Here in the wet muddy uk I replace my bearings every 6 months as it only takes a few minutes to do and costs £9
It cost nothing to pop the seals and pack in new grease and it may smooth things out for a while, but having a puller and an old cut off of seat tube to remove and fit new bearings is a must for any uni toolkit.
Another thing to check is how tight your bearing csps are done up, if they are too tight it will accelerate bearing failure and make the wheel nor spin freely.
Using some time only for cleaning… I have good Sh!t remover anyways
All my tools are from MTB repairs, so these two items are missing…
About tighting of bearing cups not sure at all. They are not overtighten but can not tell 100% sure due to torc wrench missing
I tighten cups then checked wheel to spin freely. Untighten a bit - looks pretty good
That’s all you need to do, tighten them equaly and spin the wheel, it should spin for a while before stopping but without the bolts being too loose, you can put some thread lock on them to makes sure they don’t come loose
These are interesting. The specification appears to be right but ISIS unicycle bearings are a none standard size and made especially for unicycles. I did not know of any being used in any other application. I also can not see where these bearings would be used in a remote control car.
There are different quality of bearings, but there is not much difference in them and I am certain they will do perfectly if they do fit. The KH and Nimbus ones got upgraded a few years back to increase their ability to deal with the lateral forces. Although… I struggle to tell the new ones from the old ones it is so subtle!
