By stacking several spacer disks on each other, the spring rate of the package can be increased, which opens up new possibilities for use. Foot discs are used for installing small machines, systems or devices and, for the type A, are attached with screws. Bear in mind the maximum height of the screw head. Alternatively, after the protective film has been removed, the type B can be adhered to all suitable and clean surfaces by means of the adhesive pad. see also... • Buffers GN 454 → Page 1532 Information • GN 438 Steel Zinc plated, blue passivated • GN 438.5 Stainless steel AISI 304 • Rubber underlay Acrylonitrile butadiene rubber (NBR) - - Vulcanized - - Black - - Temperature resistant up to 120 °C - - Hardness Shore A 70 • Adhesive pad (only type B) Scotch mount TM 5952 - - Double-sided - - Acrylate rubber core • Elastomer Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 5 • Other Shore hardnesses On request 1 2 3 d 1 h d 2 +0,5 d 3 +0,5 s 1 s 2 19 3  7 14 4  7,5 1,5 1,1 25 3  8 16 4  7,5 1,5 1,1 32 4  9 18 5  9   2   1,1 38 4 10 20 5  9   2   1,1 50 5 11 22 6 11   2,5 1,1 64 5 13 26 6 11   2,5 1,1 GN 438 GN 438.5 Spacer Disks and Foot Disks Steel Stainless Steel with Rubber Underlay, Vulcanized
