“Bought this as it was the same bearing (pk3459) as the Hillbilly older style trolley which has a built in spacer. It has a metal race with a plastic housing, not a great bearing but the built in spacer made it a necessary replacement without having to find and fit two seperate spacers.
I believe the newer trolleys use a different bearing which removes this problem and allows for replacement with a better one when the time comes if you so wish.”
