Vacuum & Extreme Temperature Bearings and Track Rollers - 1

This datasheet interacts with the catalogues below EX Precision Ring and Track System GV3 linear guidance and transmission system SL2 stainless steel based slide system Vacuum & Extreme Temperature Bearings and Track Rollers HepcoMotion® Vacuum & Extreme Temperature Bearings and Track Rollers are designed for extreme environments. They are available in sizes from 18 to 54mm in diameter, with a broad range of fixing styles, and with load capacities from 180 to 4,200N. They can be used with stainless steel linear and curved slides from the Hepco SL2 and PRT2 ranges. Both the VACSS range of vacuum & high temperature bearings and the LTSS range of low temperature bearings use components which are entirely made from stainless steel. Their construction and materials are shown below. Stud Austenitic Stainless Steel Nut Austenitic Stainless Steel Washer Austenitic Stainless Steel Bearing Rings Martensitic Stainless Steel Shields Austenitic Stainless Steel Cage Austenitic Stainless Steel Balls Martensitic Stainless Steel Rivets Austenitic Stainless Steel Grease Krytox LVP for vacuum & high temperature bearings - use from -15°C to +210°C. AeroShell Grease 22 for low temperatures - use from -50°C to +150°C. Screw Austenitic Stainless Steel Vent Hole (VACSS versions only) To prevent outgassing.

Vacuum & Extreme Temperature Bearings and Track Rollers - 2

Vacuum & High Temperature Bearings Hepco VACSS Vacuum & High Temperature Bearings are made entirely from stainless steel parts and are lubricated internally for life using Krytox LVP grease. They are suitable for use in high vacuum, at temperatures from -15°C to +210°C, and in the presence of oxygen. They are widely used in applications including semiconductor wafer manufacture, aerospace components, vapour deposition processes, LCD panel and plasma display manufacture and in vacuum evaporation equipment. The bearings have the same dimensions as those in the HepcoMotion SL2 range (visit...

Vacuum & Extreme Temperature Bearings and Track Rollers - 3

Low Temperature Bearings Hepco LTSS Low Temperature Bearings are lubricated internally for life using AeroShell Grease 22 which is suitable for use at temperatures from -50°C to +150°C. This lubricant enables use in much colder conditions than the VACSS bearings, opening up applications in cold stores and specialised freeze dry equipment. Through Hole Fixing type is available in two stud lengths covering most thicknesses of mounting plate. Both are available in Concentric (C) which are fixed, Eccentric (E), adjustable, and Double Eccentric (DE) which have sufficient adjustment to enable a...

Vacuum & Extreme Temperature Bearings and Track Rollers - 4

Vacuum & Extreme Temperature Track Rollers HepcoMotion Vacuum & High Temperature and Low Temperature Track Rollers are available mounted on both concentric and eccentric through hole fixing studs. They are available in diameters 25, 34 & 54mm with load capacities up to 4,200N. Track rollers can be run with any suitable flat track, or can be used as cam-followers. Materials and greases are the same as are used on the VACSS vacuum & high temperature and LTSS low temperature V bearings shown on the previous pages.
