Grainger's site is down.I remember McMaster-Carr for something and kind of remember them somewhere in Roch,but couldn't find it.I found threw searches on the net they are called Pillow block bearings/holders.Tractor supply has those in stock at the local store for me to take a look at.I am going to take a look there to see what they have.Again,I will get some pictures once I get back to the shop to show what I want to design.
