Bearing issues

So i was playing my cascade and it became responsive. I open up the bearing and found little bits a silicone in the bearing. And also found bits of silicone in the race and such. So the question is, is my bearing is unusable? Do I have to buy a new bearing?

Just give the bearing a cleaning and it should be fine:,871.0.html
