Page 33 | Highlights - Standard Parts in Hygienic Design Leveling feet GN 20 with mounting holes comply with the guidelines of the EHEDG, the 3-A sanitary standard 88-01 and the DGUV testing princip- les, making them extremely suitable for use in hygienic areas. The bottom seal protects the area beneath the foot plate from dirt. For this, the foot must be screwed on using the fixing holes and compressed accordingly. Hygienic fastenings, e.g. GN 1580 screws and nuts, 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 or the joint sealing ring, 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 leveling foot. Under normal operating con- ditions bending loads or angular loads are not uncommon and result in a reduction of load capacity, which must be taken into consideration. see also... • Leveling Feet GN 20 (Stainless Steel, without Mounting Holes, Hygienic Design ) Page 30 Information Specification • Spindle, adjustable sleeve, foot plate - Stainless steel AISI 304 - Turned • Seals, blue, FDA compliant - Sealing ring NBR, hardness 70 ±5 Shore A - Wiper TPU, hardness 95 ±5 Shore A - Joint sealing ring H-NBR, hardness 85 ±5 Shore A - Bottom seal Silicone, hardness 85 ±5 Shore A • EHEDG and 3-A Principles Page 1454 • Elastomer Characteristics Page 2158 • Stainless Steel Characteristics Page 2166 • RoHS • Cover Sleeves GN 20.1 Page 34 • Sealing Rings GN 7600 Page 36 • Wipers GN 7607 Page 37 • Screws GN 1580 Page 20 • Screws GN 1581 Page 22 Accessory GN 20 Leveling Feet continued 1 d 1 2 d 2 3 l 1 4 Type How to order 1 2 3 4 GN20-120-M16-175-B
