Air bearings - Import export

Hydrostatic bearings are characterized by practically frictionless movement. The corresponding linear guides are free from stick-slip effects and there is practically no wear on the guides. Gases (mostly air) or liquids (mostly oil) can be used as the carrying medium. Air-bearing guides are ideal, for example, for clean room applications or at high sliding speeds. If oil is used as the carrying medium, higher carrying forces can be achieved with the same size and better damping properties. Various designs are available, which can be customized at any time to meet special requirements in terms of installation space, load capacity, guide length / table diameter, drive type, position measuring system, etc.

Air-Engaged Fan Drives The HT/S Advantage is perfect for high run time applications. We started with a technologically advanced hub bearing assembly optimized for durability. We added a PFD (Piston Friction Disc) featuring the System Sentry®. This patented device reacts to heat build up caused by fan drive slippage or fan obstructions. When it senses excessive heat, the System Sentry releases, disengaging the fan drive before extensive damage occurs to the cooling system. Finally, we included a new air cartridge with a long-life carbon tip and double O-ring air seal to reduce the possibility of air leaks. The bearing assembly design, PFD with System Sentry, and air cartridge, combine to provide you with a premium on/off fan drive that will perform consistently under extreme conditions - exactly the sort of performance you've come to expect from Horton!
