Oldham Couplings Oldham Couplings KSK Max. rated torque [N∙m] Bore ranges [mm] Operating temperature [°C] Drive High stiffness Easy to mount and remove Long service life 7 φ3 ～ 16 －30 ～ 80 Servomotor, stepper motor Positioning systems, conveyors, spindle drives, actuator drives, linear drives, distributed drives Backlash free Couplings with High Torsional Stiffness The Oldham coupling is the solution for installation situations where space is at a premium. This three-part plug-in coupling grew out of an idea to develop a backlash-free Oldham coupling. It is now an indispensable part of all servo and positioning drives. The KSK, which offers precision, a lightweight design and a high level of torsional stiffness, offers an alternative solution to elastomer couplings in the case of high-precision systems.
