Water Casters use water instead of air bearings in order to supply the bearings with sufficient pressure.

Water Casters are being used for extremely heavy applications when water flooding the floors is not a problem such as dry docks and shipbuilding and when applications for water evacuation and recuperation are being anticipated such as caisson building up to 5200 tons or stadium gallery moves.

Standard water pomps make for easier and more cost efficient water supply in case of large quantities.
