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?

Well, I figured out that the one I have is a TB-105. I found a few places online to get it; warrenelectronics and starkelectronics. If I can't find one in Atlanta, I will order one.

I haven't looked for that part number, but VBX.com has always treated me well and had good prices.
