GN 42 leveling feet are simple, economically priced components.
The static load rating of these feet is limited due to the acceptable load rating of the stud (tensile strength 500/mm2).
The values given in the table assume a straight compressive load, perpendicular to the foot. The bending and buckling stress factors often found in the actual application reduce the load rating of the stud, and must be compensated for accordingly.
To insure proper leveling mount size, divide the machine weight
by the number of feet required. This will equal the pounds
or load per leveling foot.
