Jackmounts
JCM, JRM, JSM
For mounting, levelling and vibration damping of machines and equipment suited to levelling screw support in all industries.
Why choose Farrat Jackmounts?
Farrat Jackmounts offer a simple sercure and economical means of supporting and installing machinery suited to
jackscrew support.
Manufactured by Farrat they have been used for decades
in thousands of applications around the world.
Jackmounts should not be used under machines with strong vertical or horizontal shock forces (consider Isomounts, Wedgemounts or Isolated Foundations instead).
Advantages of using Jackmounts:
- Enables excellent, stable seating on uneven floors.
- High vibration damping to improve machine performance,
reduce machine wear and lower noise levels. - Reduce shock transmission to and from the machine.
- Protect floors and surroundings from the harmful effects
of vibration. - High friction grip so machines don't move.
- No bolting down or grouting for fast and economical
installation and relocation.
