As a result, they are used in applications with a focus on pure torque and power transmission as- sociated with high lateral s haft misalignments . The use of grub screws for clamping and the simple plug-in installation make oldham couplings very easy to assemble. They are suitable for a diverse range of applications and are used in general machine construc- tion in packaging machines and pumps. With the bore code K, the keyway is always integrated into both bores d 2 and d 3 . see also... • Assembly Instructions on Couplings → Page 1694 • Technical Information on Couplings → Page 1696 • Oldham Couplings GN 2242 (with Clamping Hub) → Page 1684 • Elastomer Jaw Couplings GN 2241 (with Grub Screw) → Page 1682 Information • Hub Aluminum AL Anodized, natural color • Spacer Plastic (Polyacetal POM) KU Temperature resistant up to 80 °C • Grub screws - - Steel, blackened - - For d 2 / d 3 ≤ 4, one grub screw - - For d 2 / d 3 > 4, two grub screws • Temperature range: -20 °C up to +80 °C • Keyway P9 DIN 6885 → Page 2078 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification 4 5 GN 2243 Oldham Couplings continued
