Do Four Silicone Feet Share Load Equally? Center of Gravity Checks

Grommets, Cushioning and Vibration
Key point: Total weight divided by foot count is only an initial estimate. Center of gravity, base stiffness, mounting heights and surface flatness change actual load distribution.

Scope and common interpretation errors

For small-equipment support feet, not professionally unverified load-bearing safety structures.

Height differences let some feet contact first and carry more load; base deformation then redistributes it. A single-foot compression test does not establish whole-unit balance.

Turn the review into recorded checks

StepAction and evidence
1 · Map gravity and supportsRecord equipment orientations and variable attachments, not only total mass.
2 · Check every contactObserve loaded and lifted feet on the real base and compare flat and uneven surfaces.
3 · Review local loadsEvaluate deformation, stability and long-term support in the worst orientation rather than relying on averages.

A comparison to avoid misinterpretation

A power supply or motor on one side may produce unequal marks in identical feet. Check distribution before softening all feet.

Frequently asked question

Does equal compression mean equal load?

Material, geometry and base constraints must also match.
