Type B - With mounting holes
GN20 Levelling Foot, Hygienic Design, with Mounting Holes
GN 20 hygienic levelling feet with mounting holes are certified according to EHEDG and 3-A Sanitary Standard Inc. guidelines and are therefore ideal for use in hygienic applications such as found in the food, medical and pharmaceutical industries and their associated processing and packaging.
The bottom seal protects the area beneath the foot plate from dirt. For this, the foot must be screwed on using the mounting holes and compressed. Hygienic fastenings and the correct position of the mounting holes are essential. The sealing ring above the adjustment sleeve enables fastening without dead space. Due to the wiper and the ball seal, the moving components are sealed against the environment.
The high quality finish prevents adherence of dirt and facilitates cleaning.
The values listed in the table for static load capacity refer to a purely vertical load in relation to the levelling 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.
