un-seizing bearings...

[SyC cHyLd]

Hey my profile bearings sound like they're about to go, AGAIN:mad:... i very often take them out and re-pack them with grease and stuff...

but anyways.. they're creaking like mad like they did before they seized last time.. i was wondering if anybody has any ways to maybe get them running smooth again... even if its only a temporary fix

I was told a long time ago that soaking them in gas over night may help a bit... does anybody have any experience with this or know about it at all???

Any suggestions would be great, thanks:)

Gasoline is a form of solvent. It may free them up if they are seizing, but it is not a lubricant. They are sealed bearings ( I believe...) , and not able to be serviced, so it looks like you are out of luck!

Try BC Bearing or Raeside Industrial Drives and Bearings for high quality, CHEAP priced bearings to replace em. Just bring in your old ones to have them matched up.

I don't know anything about profile bearings but sometimes you can pry the rubber seals off the sides of a bearing and re-lube them,if they are metal seals you are sol.

If you can get the seals off ,varsol might be better than gasoline as a solvent... not so flammable or stinky,and then re-grease

[corey@nsmb.com]

If you are pulling rubber off the sides, they are sealed bearings. The metal covered are called "shielded" and are not as good.

That rubber is not meant to come off, and doing so will likely compromise the seal. Typically sealed bearings develop play before they seize up.

Varsol or any petroleum based lub may also react with the rubber seals on the sides, causing it to swell and break down. Use caution!

ok but what's the worse that can happen ... you would need to replace the bearings?

In the olden days nothing used to be sealed,you could buy all the individual balls in a BB for like $2.50 so it was cheap to grease and replace them often.


if you can strip it down and regrease often there really isnt much difference between that and what they did 15 years ago.If you regrease on a regular basis(before they sieze?) and figure out what kind of a duty cycle you are dealing with you can keep on top of it and save some $.It sounds like they don't last very long as sealed bearing units anyhow

sometimes you can get the rubber seals back on

you can always buy new bearings

thanks dudes.. i dont think im gona bother.. they arent seized yet they just creak a lot and sound like they're going to
the last time i got new ones was the end of last summer... so they last around a year i guess

[marksnet]

you have the eruo profile bb do you not? where did you get bearings from last time, i think i need to replace them, as does my friend.

from what i hear profiles are more trouble than they're worth

[DangerousDean]

just go to bc bearing, i got soem new ones for my cranks, they were 10 bucks each took a day to get them in

you say that you've repacked your bearings a bunch of times. did you remove the seals, clean them out with solvent (gasoline works but its pretty explosive and dangerous) dry them thourouly and then fill them with fresh grease and replace the seals?

profile bearings are a custom size that the bearing supply places don't have.

are there any gouges in your spindle? if there is, use locktite 680.

is the bearing loose on the spindle or in the cups? use locktite 409.

hope this helps.
