Thermionics manufactures a full line of metal-sealed linear motion feedthroughs. They are all metal, using welded bellows and stainless steel linear bearings. All manual units are bakeable to 200°C fully assembled. Higher bakeouts may be used with partial disassembly. These feedthroughs are also available with a number of custom options.
NOTE: The support shaft (1/2″ dia.) supports itself beyond the mounting flange. In horizontal operation, depending on stroke, extension and payload, some deflection may occur.
