Linear & Rotary Guide Solutions

HepcoMotion's new off-the-shelf stainless steel linear and rotary guide solutions are supposed to ease the lives of those design engineers looking to design systems for vacuum and extreme temperature environments. A vital feature of the new system is the use of stainless steel. All of the bearings' moving contact surfaces are made from hardened stainless steel, which is beneficial in a high vacuum environment. The quality of this carefully-selected steel ensures that performance is optimised, and wear-generated debris is eliminated so avoiding the possibility of contamination. Outgassing, is eliminated as all free spaces within the VACSS bearings are connected to a vent hole in the bottom of the retaining screw. 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 effectively as an automated feed-in system. Grease selection is another key area of the system and it can, if the application demands it, work 'dry'. All other bearings can be lubricated internally with grease suitable for their temperature application. The VACSS vacuum and high temperature types use Krytox LVP grease, which is rated from -15˚C to +210˚C, while the LTSS low temperature bearings are lubricated with AeroShell Grease 22, rated from -50˚C to +150˚C. The bearings can also be supplied with alternative grease or without grease if required.
