sram pulley replacements

I have never had to replace mine but have had to clean and relube them several times. If your pulleys are sticking remove them from the deraileur and clean them up and replace them. If the bearings are sticking you may have to remove the rubber seal, clean and regrease. SRAM has more details on their website.
It depends what year you have. I buy my 8-speed 9.0SLs on closeouts and just salvage the unbroken parts after I shatter one in a rockgarden or wreck. The most recent one was not ball bearing and had a grooved seal in it that a metal disc on the cage fit into. In short, my experience is that aftermarkets would not work.
That's because they are made of nylon or some plastic. Next time you break a derailleur, just save the unbroken pieces. Those pulley wheels usually survive.
What year is your derailleur? I have about 5 busted 9.0 laying around, I coulde easily drop a few spare pulleys in the mail.
I just replaced mine but that was because the cartrige bearing was so worn the ball bearings fell out and I couldn't get them back in. The teeth where worn to sharp points but I noticed no problems with shifting. As they take no load I don't really think it's worth replacing them until they fail.
The lower pulley is standard but all the sram upper pulleys I have seen use a big bushing with two holes in so you pretty much need a sram pulley.

The only problem I could see with that is some part of the mech is going to take over the job of moving the chain during shifting. Also It could rub during normal riding. Perhaps not the best thing if you have one of the plastic sram mechs.
I just ground off the nubs that fit in the second hole in the sram jockey wheel and fitted some shimano jockey wheels.
I don't know why sram decided to use a proprietary upper pulley in the first place, the shimano method has no problems and spares are easy to find.
The shimano ones are a fair bit bigger but work fine.
