The metal bellows also reliably com- pensates for shaft misalignments and runout tolerances. The clamping hubs make bellows couplings very easy to install. They are used in applications where precise position and movement transmission is required, such as in the servo drive systems of machine tools and in industrial robots. see also... • Assembly Instructions on Couplings → Page 1694 • Technical Information on Couplings → Page 1696 • Beam Couplings GN 2246 → Page 1690 • Elastomer Jaw Couplings GN 2240 (with Clamping Hub) → Page 1680 Information • Hub Aluminum AL Anodized, natural color • Bellows Stainless steel AISI 304 NI • Socket cap screws DIN 912 Steel, blackened • Crimp ring Brass • Temperature resistant up to 120 °C • ISO Fundamental Tolerances → Page 2151 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 5 • Bore with keyway On request
