Cast iron with sealed bearings would be the longest lasting but you'd see some wear on both them and the tracks after some time.

Polyurethane, polyolefin, or nylon with sealed bearings would all be better choices than rubber.

All the urethan/nylon ball bearing wheels I can find are bigger than 2 inch.

My fault I missed the 2" size. You're going to be limited in that size to likely roller or delrin bearings. Neither is terrible just won't last as long.

Yeah the first one looks great, until you see the price. 16 x $30 - Dang. The second choice looks like what is there, and they have lasted about 15 years.....so I guess I will go with them. Thanks

Yea casters themselves are just crazy expensive. I ordered some last year for work that were like $400/piece. Definitely a cost/benefit part.

I actually found rollerblade wheels small enough. The "aggressive" style rollerblade wheels are 55mm. There is about an inch play each direction on the lift, so it should work. About the same price as the rubber ones from mcmaster when you factor in the bearings and spacers that you have to buy seperate with the rollerblade wheels.
