Round Steel Air Caster Modules are the ideal machinery moving equipment, and are very strong and robust structures capable of supporting the proportionate weight of loads weighing many tons. They have a profile height of under 3 inches. They are the most suitable equipment for lifting and moving heavy machinery, and are often attached permanently to machinery that requires repetitive movements, via an optional steel mounting plate.

The low profile of this caster module requires less than 3″ clearance.Ordinary 90-110 psi air is required to inflate it. This air bearing is ideal for the fixed application of modular air bearings.

Here is a typical round steel module system footprint diagram highlighting the various elements of the system and how they connect together.

Please note: Any Hovair round steel air bearing system can be operated via optional remote control. If a remote control the air flow control valves shown above are replaced by air inlet ports and all module air pressure regulation is done at the remote control box
