EK 20 A (red) R+W Servomax Elastomer Coupling Insert

The R+W EK A (Red) TPU elastomer insert is designed for Servomax backlash-free elastomer couplings where superior vibration damping and shock absorption are required. Manufactured from high-performance Thermoplastic Polyurethane (TPU), the red insert combines the flexibility of rubber with the durability and wear resistance of an engineering polymer, helping to protect motors, gearboxes and driven equipment from damaging load peaks. Its softer hardness provides increased damping characteristics while maintaining reliable backlash-free torque transmission, making it ideal for applications with fluctuating loads, frequent start-stop cycles and a need for smoother operation.
