Skelang Leveling Machine Caster Model-80, Large Top Plate Leveling Wheel with Retractable NBR Pad for Heavy Workbench, Electric Equipment, Vending Machine, Total Loading Capacity 3300 Lbs, Pack of 4

These are excellent value and well built. I have them under a metal welding table and a wood workbench. They work great and are sturdy. I will buy more when I need them.

Installed on my assembly/outfeed table for woodworking. Very well made and work perfect.

These things are built like tanks. Given the low price, I was a bit concerned that I was going to end up with some flimsy, plastic wheels and housings.When I opened the box I was immediately impressed with the heft and quality of the materials and design. I’m using them for a big heavy woodworking bench so they need to be rock solid, and I haven’t been disappointed.My one concern is that the sprockets that adjust the height are the only part of these assemblies that are made of plastic. I haven’t had to adjust the height yet under significant load so I’ll have to come back and update the review to tell you whether the plastic sprockets are an issue or not.However, so far I’m thoroughly impressed.

Did not come with screws. That’s OK because I expected them to be crap but still. These do allow my heavy work bench to be repositioned and made stationary, but the adjustment wheels are fiddly and uncomfortable to use but they are sturdy. Does not provide any significant lift for leveling but maybe your floor is not as bad as the one in my garage

Great solution for my milling machine. Had to drill and tap a few holes in the base to accommodate 3 points of contact rather than the 1 point the mill base was designed for resulting in a more sturdy design. This left the single holes free to mount to floor when not needing to be moved. These are well built easy to raise and lower even under weight. Roll around easily then when in place spin the finger wheels to level and secure in place. I will be buying more for a lathe soon.
