Product Description
The R+W EK B (Green) TPU elastomer insert is engineered for Servomax backlash-free elastomer couplings requiring maximum torsional stiffness and precise motion control. Manufactured from high-performance Thermoplastic Polyurethane (TPU), the green insert offers outstanding durability, wear resistance and long service life while delivering highly responsive, backlash-free torque transmission. Its harder material provides reduced rotational wind-up and improved positioning accuracy compared to softer insert options, making it ideal for servo drives, automation systems, robotics and other high-dynamic applications where precision, repeatability and performance are critical.
