Bearings are bearings. Some have tight seals, some do not, some are even
just shielded. Buy a 10 pack from VXB and pop new ones in. and Pulleys
are pulleys. I don't think I have been running OEM pulleys since 1989.
or Get some shimano pullleys and put them on your sram derailluer.
I personally run thin washers that overlap the seal. grease that gap for
sure. Grease the bejesus out of the bearing also. its not like you are
going 2000 rpm and have to worry about grease churning and
bearing overheating. And if you seized them once, they are shot. Yes in
my younger poorer days i was known to run toothpaste in them to clean them
back up, but at some point the fits are gone and its all wobbley. so really
probably get new bearings. especially if you weren't careful
about cleaning it well, warming it, wd-40 it, oil it, warming it,
air blowing it, etc, etc, then greasing it, working it in. blowing it,
greasing it, cleaning seals, checking for damaged seals, etc, etc, etc,
etc. these aren't forgiving cup and cone bearings, these precision fits
with are like 10th of your hair thickness. If these are type where you
can't push the bearing out and push new ones in,then yes just get some new
pulleys.
