Linear Profile Bearings - Clatter Noise, Maintenance?

[Tenson]

Okay I took the worst sounding bearing apart, cleaned and re-assembled. Thanks for the help Jazz.

Sadly it seems just the same! I couldn't see any damage to the plates. Interestingly these bearings have no plastic tubes, see the image.

That said, it probably is to do with the plates as they quiet down with some weight on them, presumably pressing the balls onto the main body and keeping them off the plate edge.

Ok well this is not unusual but it does show they are older than 3yrs because for the last 3yrs every one i've used has the tubes. Before that they didn't.! Infact the latest ones the plates are actually fastened using little screws and can be removed without taking the end caps off.

Regards the weight making them quite down then again thats not unusal and they will move more freely also and take that notchy feel away.!

Honestly I wouldn't worry about it put them back together and use.!

Good idea, if you have a decent set of weighing scales this might show a difference between the one you stripped down and one of the quieter ones.

Really not worth the effort has they will be fine and besides there's very little can be done about it if they are worn out because the body will be worn not just the balls.!
Even if they are worn they will still be miles better than the cheap round rail bearings unless completely knackerd which they don't look or sound to me.
