Co-Ordinate Measuring Machine isolated using a reinforced concrete foundation block supported on
STUDFLEX Rubber Pads.
Quad Layer STUDFLEX Pads in
Natural Rubber providing:
• 14.4mm deflection on each Pad giving an
isolator Natural Frequency of 4.8 Hz.
• System capable of providing isolation of
vibration down to nearly 7Hz thus giving
maximum protection against disturbances
from the presses and other mechanical
plant which are in close proximity.
Industrial Isolation
Our wide range of anti-vibration mountings provide the right level of reduction that
is required so the forces produced by building and industrial equipment are
attenuated
We are involved in:
• Power Generation
• Air Handling Units
• Plantrooms
• Pipe work
• Cooling Towers

Industrial Isolation
• Our Key Advantage? Our in-house data processing capability enables us to evaluate the
most complex problems in 6 Degrees of Freedom using our proprietary CRMS software.
• CRMS output is balanced with real world experience in all
types of applications by highly trained Applications Engineers.
• We do this to ensure that there are no factors that would
affect performance that go unreported.
We analyse:
• Translational modes:
• Vertical
• Transverse
• Longitudinal
• Rotational modes:
• Yawing
• Pitching
• Rolling
