We have a house on stilts. The house has a cargo lift that's basically a metal cage that rides up another metal cage from the ground up to the living floor (about 25 foot rise) by way of a chain hoist. The inner cage runs along the outer cage and is kept in line by 2 inch wheels - two on each corner at 90 degrees from each other. The wheels are starting to break down. They appear to be rubber with no bearings. Direct Florida sun for part of the day. The lift is pretty rough / jerky. Watching it run it appears to be a combo of the deteriorating wheels and rusty /dry chain on the hoist. Looking to replace the wheels what material would you use and would you use a bearing?

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.

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

I'd go to harbor freight and pick some out. Almost anything other than rubber should last a few years.

Since this is exposed to Florida, I'd go cheap and just plan to change them every 5 years.

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.
