This Oldham coupling is intended for use in the driveline of a Citroën 11CV Perfo engine. The coupling connects two shafts with limited alignment accuracy and provides torque transmission at low to medium speeds. The design with a central sliding element compensates for radial and axial deviations and reduces vibration in the system. The part matches the original mounting points and dimensions of the vehicle. The material selection focuses on dimensional stability and wear resistance under normal operating conditions. The coupling is used during service, repair and restoration of classic vehicles of this model series.
