Product description


Leveling feet GN 20 with mounting holes comply the guidelines of the EHEDG, with the 3-A sanitary standard 88-01 and the DGUV testing principles, making them suitable for use in in hygienic areas.

The bottom seal protects the area beneath the base from dirt. For this, the foot must be screwed dowon using the mounting holes and compressed accordingly. Hygienic fasteners such as GN 1580 screws and nuts, and the correct position of the mounting bores in the mating surface are essential for a properly sealed foot to surface installation. The sealing ring above the adjustment sleeve enables mounting without dead space. Due to the wiper or the joint sealing ring, the movable components are sealed against the environment.

The high surface quality prevents dirt from adhering and facilitates cleaning.

The values for static load capacity listed in the table refer to a purely vertical load to the leveling foot. Under normal operating conditions, bending loads or angular loads are not uncommon and result in a reduction of load capacity, which must be taken into consideration.

Sealing Concept

The design shown below of a GN 20 leveling foot in Hygienic Design illustrates how the different seal arrangements can be configured.

Drawing Application example GN 20


For parts that are designed in Hygienic Design, seals have the central function of protecting dead spaces, gaps and cracks from penetration of cleaning fluids or product residues.

This requires a defined pre-tension / pressure of the seals and wipers for a reliable and permanent seal when installed. Within the Hygienic Design range, seal installation spaces and seal cross sections are therefore calculated and designed using simulation software in such a way that the necessary surface pressure is achieved during installation and at the same time, the seal material is not overstressed.

A fundamental differentiation can be made between static and movable seals:

The static seals shown in the application example below (at the top towards the mounting surface (sealing ring) and at the bottom towards the installation surface (bottom seal)) are tightened during installation. It should be ensured that all surfaces in contact with the seals have a surface quality of at least
Ra 0.8 µm.

The movable seals on the adjustable sleeve (wiper) and on the ball joint (joint sealing ring) of the foot are designed in such a way that they allow an adjustment in height and angle. Also with these, the installation space together with the seal cross section ensures a gap-free, pre-tensioned seal.

Depending on the version and application, it may be necessary to replace the seals in case of damage or for preventative maintenance. For this purpose, JW Winco offers the respecitve seals separately as a standard part under Sealing Rings GN 7600 for spare part requirements.
