in bouwverslagen kwam ik wat problemen tegen met de standaardlagers; het lijkt of die met oranje rubber geseald zijn, maar dat is niet zo.
Ze zijn met metalen ringen geseald, die op zich weer "bekleed"zijn met oranje kunsstof of rubber. En dat schijnt nou net niet zo lekker te lopen, vanwege "aanlopen".
Daarom dacht ik ze meteen maar te gaan vervangen.
quote van GS forum:
I was a little disappointed with the nice looking bearings though, they all felt kind tight and binding. This is normal because all kit bearings come packed with grease no matter who makes them. The problem with the TM G4S ones is that even when you flush out all the grease and then re-oil, you may not find that all of them will be smooth. This is because the orange seals are not true rubber seals, instead they are rubber-coated metal seals and the coating isn't the best quality. Some of them just purely binds the bearing's outer cage to the inner cage. I use 400 grit sand paper to smoothen out some of them but as you'd guess, this does not work well on rubber but it did improve things a little bit.
