Off-the-shelf solution suits high temperature environments

The linear and rotary guide system is made from stainless steel, which means it is inherently clean, non-corrosive and able to withstand high temperatures. All free spaces within the VACSS bearings are connected to a vent hole in the bottom of the retaining screw, eliminating outgassing. Another advantage of the Hepco system is that a six bearing carriage system, unlike a re-circulating ball rail system, has the ability to traverse a large gap in the rail. This design allows the carriage plate (and component placed upon it) to move from the outside into the vacuum chamber and act as an automated feed-in system. The Hepco system works with or without grease and is available as both concentric and eccentric. It can be installed easily and offers a long service life. Typical applications include semiconductor wafer and aerospace component manufacture, vapour deposition processes, LCD panel/ plasma display manufacture and vacuum evaporation equipment.
