Arcusaflex AC‑H 11 Coupling | REICH Rubber Coupling

REICH Arcusaflex AC‑H 11 SM Rubber CouplingThe REICH Arcusaflex AC‑H 11 rubber coupling is a heavy‑duty torsionally flexible coupling designed for large diesel engines and industrial drive systems. It ensures reliable torque transmission while effectively absorbing torsional vibrations and shock loads between the engine and driven equipment.The AC‑H 11 series is widely used in marine propulsion, generator sets, compressor drives, and heavy industrial machinery, where high torque capacity and drivetrain protection are essential.Different elastomer hardness versions (WN, NN, SN, UN) allow engineers to match the coupling to the required torque load, vibration damping characteristics, and operating speed.Product InformationProduct: Arcusaflex AC‑H 11 Rubber CouplingBrand: REICH KupplungenSeries: ARCUSAFLEX AC‑HModel: AC‑H 11Type: Flexible Rubber Flywheel CouplingTechnical Specifications – AC‑H 11VariantRubber HardnessNormal TorqueMax TorqueNormal SpeedWNShore A 5516000 N.m40000 N.m2000 rpmNNShore A 6518000 N.m54000 N.m2000 rpmSNShore A 7520000 N.m60000 N.m1800 rpmUNShore A 8523000 N.m60000 N.m1800 rpmThese variants allow selection of the appropriate torsional stiffness and torque capacity for heavy engine applications.ApplicationsThe Arcusaflex AC‑H 11 coupling is commonly used with high‑power diesel engines and industrial drive systems.Caterpillar EnginesCAT 3516CAT 3512Cummins EnginesCummins KTA38Cummins QSK45Industrial UsesMarine propulsion systemsPower generation equipmentIndustrial compressor drivesHeavy industrial machineryThe coupling helps ensure smooth power transmission and reduced torsional vibration in engine‑driven systems.Key FeaturesHigh torque capacity for heavy diesel enginesTorsional vibration damping for drivetrain protectionFlexible rubber element for shock absorptionCompensation for angular and axial misalignmentDurable construction for continuous industrial operationMultiple elastomer hardness optionsLong service life with minimal maintenanceReplacement Part Numbers12011200420004ARCUSAFLEX AC‑H 11 SNREICH KUPPLUNGEN AC‑H 11REICH COUPLING ACH 11 UNREICH AC‑H11 NNThese references help procurement teams identify replacement Arcusaflex AC‑H 11 couplings or rubber elements for engine and generator drive systems.
