R+W EK Series Elastomer Couplings
R+W EK elastomer jaw couplings for general industrial drives with damping and low inertia.
EK elastomer jaw coupling
R+W EK series couplings use an elastomer spider between two jaw hubs to transmit torque while damping vibration. The design accommodates angular and parallel misalignment in pumps, fans, compressors and general industrial machinery.
Zero-backlash performance depends on spider hardness, fit and operating condition -- confirm requirements with application data.
Selection factors
Torque and service factor
Size the coupling for peak torque and application duty class.
Spider material
Different elastomer hardness affects damping, temperature limit and torsional stiffness.
Bore and keyway
Shaft bore, keyway and clamping style must be confirmed for each order.
