U-type 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

U type plate vibration isolator installation guidelines:

Mounting in unthreaded through holes

Kolejność operacji:

1. lift a machine

2. screw the mounting screws into the threaded bushings of the vibration isolator

3. lower the machine with the screwed in vibration isolators

4. level the machine by turning the mounting screws right – lifting, left – lowering, level evenly on all mounting screws – keep the screws in a vertical position relieve the load on the vibration isolator before leveling.

5. secure the leveling of a machine by clamping a spring washer on the mounting screws using a locknut

6. verify the leveling of a machine and the upright position of the mounting screws after ca 1 week of operation and correct the leveling if required.

A machine should be leveled at a minimal distance from the floor, keeping the mounting screws in a vertical position.
