Vacuum & Extreme Temperature Bearings and Track Rollers are designed for extreme environments. They are available in sizes from 18mm to 54mm in diameter, with a broad range of fixing styles.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 vacuums, 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 com-ponents, vapour deposition processes, LCD panel and plasma display manufacture and in vacuum evaporation equipment.The Bearings have the same dimensions as GV3 Standard Bearings

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, for applications such as cold stores and specialised freeze dry equipment.

Through Hole Fixing type is available in two axle lengths covering most thicknesses of mounting plate. Both are available in Concentric type (C) which are fixed, Eccentric type (E), adjustable, and Double Eccentric type (DE), which have sufficient adjustment to enable a Carriage to be disengaged from the Slide .
Blind Hole Fixing type (BHJ) allows mounting into a solid machine base where through mounting holes are not possible, or where the thickness of the mounting plate is too great. The Blind Hole Fixing type is also useful where adjustment from the front is preferred or where access to the opposite side of the mounting hole is restricted. They are available in the fixed position Concentric type (C) and adjustable Eccentric type (E).
