Compact Power Transmission with Advanced Vibration Damping

The A Series Star Elastic Coupling is a high-performance, Rotex-standard solution for modern drive systems. Designed for axial plug-in installation, this jaw coupling combines a compact footprint with the superior damping properties of engineering plastic elastomers. It is engineered to minimize surface pressure on the involute teeth, ensuring that even under overload conditions, the components remain free from wear and deformation.

Why Choose the A Series?

• Low Inertia & Compact Design: The streamlined structure reduces rotational inertia, making it perfect for precision motor applications requiring rapid start-stops.

• 98Sha Engineering Plastic Elastomer: Our premium star-shaped spiders offer excellent wear resistance and cushioning. The elastomer is uniquely constrained by convex claw blocks to prevent deformation from centrifugal force or impact.

• Maintenance-Free Operation: Designed for a long service life within a temperature range of -35°C to +80°C, requiring zero lubrication or ongoing maintenance.

• Precision Involute Tooth Profile: The large concave surface area ensures that pressure is distributed evenly, protecting the integrity of the coupling during high-torque transmission.

• High-Speed Stability: Capable of handling speeds up to 5000 RPM with a rated torque reaching 500 N·m depending on the specific configuration.
