Precision Rotex Series Flexible Plum Couplings for Industrial Motion Control

Our Rotex Series Jaw Spider Couplings (also known as Plum or Star Elastic Couplings) are designed for compact, high-efficiency power transmission. Engineered with a focus on vibration reduction and axial compensation, these couplings provide a maintenance-free solution for various industrial environments.

Core Structural Features

• Compact & Low Inertia: Lightweight design ensures minimal rotational inertia, making it ideal for high-speed applications.

• High-Grade Elastic Elements: Utilizes premium engineering plastics (Polyurethane) that provide excellent cushioning and wear resistance.

• Advanced Elastomer Protection: The elastomer is constrained by convex claw blocks, preventing internal deformation from impact or external deformation from centrifugal force.

• Optimized Surface Pressure: The large concave surface area of the convex claws keeps surface pressure on the involute teeth extremely low, preventing wear or deformation even under overload.

• Easy Installation: Features a practical axial plug-in installation design for rapid assembly and maintenance.
