Hi Jon,
The bearings came off ebay, if you search " BEARINGS 6200 - 6209 2RS " it will come up with list of sellers, I used the first listed Bearingoptions, cheap and really fast.
I ordered the bearings before ordering the Unistrut, and took dimensions off the unistrut website. When my strut was delivered It differed slightly in size from original 'Unistrut" and I needed to reorder. Ordered 32mm O/D and found 31mm would have fitted but used 30mm the next stock size.
To save you time they are listed by QTY 10x Type 6200 2RS I/D 10mm O/D 30mm Width 9mm
I used the 2mm thick heavy duty strut .... if you are using light duty, its likely a larger diameter will fit so definitely measure first
hope that helps, let us know how you get on .......
regards Colin
