These are renderings of the antenna base design. What do you think ?
This is the construction of the antenna base. It has a side-rail to keep it absolutely steady when turning, a spring to take load out of the side rail and a few ball bearings (9 to be exact).
This is a close-up of one of the rollers around the base. There are 6 of these and each of them is capable of handling about 400 Kg weight. Each roller has an elastic dampener (nitrile rubber) to take away the small scratches in the rail.
This is the spring that takes away most of the load from the side rail. The ball bearing is more than capable of handling 10 times the load it will ever get in this installation. It was chosen merely by the dimensions than the load capacity.
Both upper and lower parts of this carousel are adjustable for off-center conditions. This is essential to be able to straighten things up.
