Probably not but, in my experience, the actual sealed bearing you find on some high end derailers usually outlast the jockey wheels, either because of wear or the plastic of the pulley cracks.

Reminds me of a story worth repeating from my bike shop days. A mother and her 13-year-old son came in the shop with a bike she'd bought for him 2 months earlier. She said that they'd brought the bike back for gear adjustments three times in those 2 months because the gears kept spontaneously going out of adjustment and that if the bike needed its gears adjusted one more time, she'd return it and get her money back.
I asked, "Has anyone [looking at the son] been attempting to adjust the gears at home?"
She answered hotly, "They asked that last time! I asked my son, and he said no. MY SON DOESN'T LIE TO ME!!"
I looked at the son again. He looked back at me sheepishly.
I took the bike to the repair department and adjusted the gears. Then I dabbed some green touch-up paint on the adjustment screw threads and on the top of the screw heads. Brought the bike back up and pointed out the painted adjustment screws: "This way, if someone tries to turn the adjustment screws, you'll see cracks in the paint."
Off they went. As far as I know, the bike required no more gear adjustments after that.
Looking back, I'm glad I didn't give in to the impulse to say, "A 13-year-old boy who doesn't lie to his mom? Call the Guinness Book of Records!"
