Minus K Technology


Minus K vibration isolation systems can be made vacuum compatible so they can be used right inside vacuum chambers. In addition to their superior vibration isolation performance, this offers other advantages of much lower payload weights, more compact systems, and eliminates problems associated with vacuum chamber feed-throughs.

Our vibration isolation systems have also been used to support entire vacuum chambers. This offers the advantages of more standard designs and lower costs in some cases.

 

Modifications for to the isolators based on your application requirements could include:
• Use of Stainless Hardware
• Removal of Paint and/or Powder Coating
• Removal of Anodizing
• Replacement of Nylon or Plastic Parts
• Electroless Nickel on Steel Parts
• Venting Blind Holes
• Use of Vacuum Grease for Low Outgassing
• Passivation of heat treated parts
• Bare Aluminum
• Ultra Sonic cleaning of parts
• Mechanical tilt flexure

We'll need to provide custom pricing for vacuum applications (the price is typically 3 times the standard units)
