At a spindle thread size M 10 and higher, the static load of the leveling feet GN 21 is limited owing to the permissible contact pressure of the adjustment spindle acting on the base plate (at a spindle strength ≥ 500 N/mm2). The values given in the table (valid for type D0 without rubber underlay) assume a clean pressure load perpendicular to the base plate. Bending and buckling stress which often occurs in practice results in a lower load-bearing capacity of the adjustment spindle and may have to be taken into account.
The details given on strength are non-binding guide values without any liability. In general, they do not constitute a warranty or quality.
The user must determine from case to case if a product is suitable for the intended purpose or use. Environmental factors may influence the stated values.
