The best bet is to use a caster with all steel construction or with a cast Iron wheel. Use the caster for the mobility of the table, not the leveling of the table. On mine I have 360deg swivel casters on all four corners and then levelig pads adjacent to the casters that have enough adjustment to pick the caster off the ground and level the table. This way the table is firmly in place and level. I have cad and pdf files of mine if youd like to see, drop me a PM.
