VMC Group UN Series Heavy-Duty Spring Isolators are most frequently used to support machines on deep concrete foundations such as forging hammers and roll grinders. The UN Series isolator supports the structural members within the foundation. By adjusting the UN Isolator, both the machine and the foundation may be leveled. 

Separate snubbing and damping controls are available. A load range to 35,000 lbs. per isolator and deflections to 1.5" result in excellent shock and vibration attenuation.

Features & Benefits

  • 5,000 lbs. per isolator load range provides high vibration damping for heavy industrial equipment
  • Support of structural members permits leveling of both the machine and the foundation

Applications

  • Punch presses
  • Milling machines
  • Compressors
  • Pumping equipment
  • Drill presses
  • Drop hammers
  • Forging hammers
  • Lathes
