I'm going to restore my window unit this year. I've been looking @ ball bearing pillow blocks with zirk fittings.
I have no idea how old mine are, the unit is 10 years old i Believe. Got it from a lady who was told it would cost 2k to service it/fix it.
My question is it best to not reinvent the wheel or try and see i can make some work.
I figured it would be better then the bushing ones they sell.
