About Star-shaped elastic coupling (GR)
This product is a torsionally flexible coupling with fail-safe features. Its structure is compact, lightweight, and has low rotational inertia,but can transmit high torque. The coupling's high operating quality and lifespan are due to all surfaces being precisely machined. Thespider-shaped elastomer made from special polyurethane effectively dampens vibrations generated during operation, absorbs the shocks from uneven operation at the power end and equipment end, and avoids stress concentration due to its drum-shaped tooth design, thereby effectively correcting axial, radial, and angular installation deviations.

Key Features
Zero backlash, high transmission accuracy: Pre-stressed assembly ensures zero rotational backlash, making it ideal for servo systems, precision drives, and applications involving frequent forward and reverse operation. The elastomer is constrained by the claw blocks, preventing deformation or fragmentation under impact.Superior shock absorption, vibration damping, and noise reduction: The central polyurethane (PU) star-shaped pad offers high elasticity and resilience, effectively absorbing vibrations and impacts to protect bearings, pumps, and motors.
