I have a ChannelMaster 9521A rotator. When I installed it several years ago, I installed a bearing above it to keep pressure off of the bearings in the 9521A. I tried to rotate it after a couple of years, but the upper bearing is rusted, and has one area that it will not rotate through. I don't remember where I purchased the upper bearing. Does anyone have an idea where to get one?
