Precision A Type Star Elastic Couplings for High-Efficiency Pumping

Our A type star elastic coupling is an ideal, cost-effective substitute for KTR Rotex Aluminium Alloy AI-D/AI-H 19 models. Engineered with a compact frame and small inertia, this coupling is specifically designed to enhance the performance of stationary pumps by providing superior cushioning and wear resistance.

Advanced Structural Features

• Engineering Plastic Elastomer: Utilizes high-grade engineering plastics as elastic elements, offering excellent vibration reduction and maintenance-free operation within a temperature range of -35°C to +80°C.

• Optimized Surface Pressure: The large concave surface design of the convex claws minimizes surface pressure on the involute teeth, preventing wear or deformation even under overload conditions.

• Durable 98SHA Hardness: The elastomer features a standard hardness of 98 Shore A (98SHA), ensuring reliable nominal torque transmission for demanding industrial tasks.

• Deformation Resistance: The elastomer is constrained by convex claw blocks, effectively avoiding internal deformation from impacts or external deformation caused by centrifugal forces.

• Easy Axial Plug-in Installation: Designed for quick and secure assembly, significantly reducing maintenance time for stationary pump systems.
