Leveling feet GN 148 are designed for limiting vibration on heavy machinery, thus increasing the lifetime of the machines and reducing noise pollution.
The structure of these feet helps absorb horizontal forces. The version with tear-off lock (identification no. 2) protects the feet from destruction caused by tear-off under excessive tension loads.
The information about load bearing capacity are non-binding guide values and rule out any liability. They constitute no general warranty of quality and condition. The user must determine from case to case whether a product is suitable for the intended use.

The first step is to determine the static load F per leveling foot. With appropriately arranged leveling feet and thus an evenly distributed load F, this value is calculated using the following equation: Force due to weight of the machine [lbf or N] / Number of leveling feet = Static load F [lbf or N] per leveling foot Use the calculated static load F to select a leveling foot from the table, making sure that the static load F lies as close as possible to the static load capacity without exceeding it. The associated stiffness R of the selected leveling foot is also taken from the table. Static load F [lbf or N] per leveling foot / = Actual compression s [in or mm] Starting from the calculated actual compression s, the achievable degree of insulation as factor of the interference frequency can now be taken from the chart shown above. To optimize the achievable degree of insulation, the number of leveling feet may be changed such that the static load F for each leveling foot is as close as possible below a load capacity value given in the table. This will increase the compression s which, in turn, results in a higher degree of insulation. |
