Product Description
The R+W EK1 Servomax backlash-free elastomer coupling is designed to provide precise torque transmission while effectively damping vibration and shock loads in servo-driven systems. Supplied with pilot bores for custom machining to suit specific shaft and keyway dimensions and a replaceable elastomer insert, the EK1 delivers backlash-free performance, excellent vibration isolation, and reliable compensation of angular, radial and axial misalignment. Its compact, lightweight design makes it ideal for servo motors, positioning systems, packaging machinery and automated equipment where smooth operation, protection of drive components and high positioning accuracy are essential.
