* Complete the description of the standard item needed by adding OS (without plastic cap), KR (with plasitc cap non-gliding) or GV (with rubber, vulcanised).# The values reported in the table refer to the heaviest type GV.

Additional information

Assembly screw

Stainless steel A2, glued.

Base

– Zinc-plated steel, blue passivated (type OS and KR). <BR>- AISI 304 stainless steel (type GV).<BR>

Features and applications

The levelling elements GN 440.1 are an easy and very reasonably priced foot design variant.<BR>The static load capability of these levelling feet has been tested in a series of tests involving a tension-compression test bench. <BR>The values given in the table assume a straight compressive load perpendicular to the articulated foot. The bending and buckling stress factors often found in practice reduce the load rating of the screw and must be compensated accordingly.

Internal thread

Zinc-plated steel, tensile strength 500 N/mm².

Standard types available

– Type <STRONG>OS</STRONG>: without plastic cap. <BR>- Type <STRONG>KR</STRONG>: with 73 Shore hardness thermoplastic rubber cap (SANTROPENE), non-gliding. <BR>- Type <STRONG>GV</STRONG>: NBR rubber (PERBUNAN), hardness from 65 to 75 Shore, vulcanised to the base.
