Hepcomotion's bearings can create linear and rotary guides for extreme temperatures

Apr 30,2014
Hepcomotion has introduced its off-the-shelf stainless steel linear and rotary guide solutions, which are aimed at design engineers looking to design systems for vacuum and extreme temperature environments. The bearings are available in sizes from 18–54mm in diameter, with a broad range of fixing styles and load capacities from 180–4,200N. They have the same dimensions as the bearings in the HepcoSL2 range and can be supplied ready-mounted onto an SL2 or PRT2 carriage plate, or as components that users can mount onto their own carriage assemblies. They are suitable for use in applications such as: semiconductor wafer and aerospace component manufacture; vapour deposition processes; LCD panel/ plasma display manufacture and in vacuum evaporation equipment. The LTSS bearings also appear in low-temperature applications such as cold stores and specialised freeze dry equipment. Key product benefits * The Hepco system is a six-bearing carriage system; unlike a re-circulating ball rail system, it 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. * Hepco’s vacuum and extreme temperature bearings are simple and cost-effective to integrate, and deliver consistently excellent results throughout a long operating life. * Stainless steel is the default choice for a vacuum because it doesn’t outgas, is inherently clean and non-corrosive and therefore suitable for vacuum applications which require a high level of cleanliness. Stainless steel also doesn’t melt in high-temperature environments. * The bearings are available as both concentric and eccentric, which extends the life of the system as when wear/play starts to develop in the system, it can simply be eliminated by adjusting the eccentric. * Grease selection is another key area of the Hepco system and it can, if the application demands it, work ‘dry’.
