star type coupling, a type of elastic coupling, is engineered to efficiently transmit torque while accommodating misalignment between shafts. It consists of two hubs and a star - shaped elastomeric element, usually made of durable polyurethane or rubber. This design allows for angular, parallel, and axial misalignment compensation, reducing mechanical stress on connected components. The elastomer also absorbs vibrations and dampens shock loads, minimizing noise and enhancing equipment lifespan.

Can star couplings be used in high - speed applications?
Yes, many of our star couplings are suitable for high - speed operation, with maximum rotational speeds reaching up to 10,000 RPM, depending on the size and design.
How do I select the right size for my application?
Consider factors like shaft diameter, required torque, misalignment tolerance, and operating speed. Our technical team can assist with customized recommendations.
What is the lifespan of the elastomeric element?
Lifespan depends on operating conditions such as load, temperature, and vibration. Under normal circumstances, the elastomer can last 3 - 5 years, but we offer replacement parts for longer service.
