Square aluminum air caster modules are strong and robust structures capable of supporting the proportionate weight of loads weighing many tons. As machine moving equipment, they have a profile height of just over 2 inches. They can slide under loads and machines with suitable heights, often making them an ideal solution as machine moving equipment. They are also the most suitable module for when a load can be placed directly onto the modules. Ask your Hovair Systems support contact for details.

The low profile of this module requires just over a 2″ height clearance. Ordinary 90 psi air is required to inflate it.

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

Please note: Any Hovair square aluminum air bearing system can be operated via optional remote control.
If a remote control is used, 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.New To Air Bearings? For Everything You Need To Know –
