t-type-bushing-vibration-isolators

To optimize the selection of a vibration isolator one should consider:

  • device’s full mass
  • amount of points of support
  • load concentration on a point of support
  • rotational speed of spinning/rotating elements
  • possible deflection

Order of operations:

  1. anchor the vibration isolator to the floor or a support structure at the mounting location – make sure that the coaxiality is kept between the mounting screws and the holes in the base or the frame of a machine
  2. lower a machine inserting the mounting screws into the holes in the base or the frame of the machine
  3. level a machine by turning the lower leveling nuts right – lifting, left – lowering, level evenly on all mounting screws keeping the screws in a vertical position
  4. secure the leveling of a machine by clamping a spring washer on the mounting screws using the upper locknut
  5. verify the leveling of a machine after ca 1 week of operation and correct the leveling if required.

A machine should be leveled at a minimal distance from the floor or the support structure, keeping the mounting screw in a vertical position.
