RUBBER ELEMENTS – THE HEART OF THE SHAFT COUPLING

1. What is a rubber coupling?

Rubber coupling is also known as rubber coupling shock absorber, shock absorber washer. The English term is rubber, element rubber, spider coupling. It is a component of the entire coupling set, made of rubber.
Rubber coupling shock absorber is located in the middle of the coupling set with the main function of shock absorption to ensure close coordination between the parts when the coupling is operating to transmit power.

2. How to distinguish genuine Rotex KTR Rubber Elements

Through the research process of KTR experts. Genuine KTR Rotex rubber joint gasket products meet the requirements:

• Good absorption.
• Elasticity.
• Withstand high temperatures.
• Withstand negative temperatures.
• Withstand light.
• Withstand oil / grease.
• Withstand corrosive chemicals.
• Withstand dust and moisture.
• Resistance to wide-area electricity transmission.

According to the video, for genuine Rotex Rubber Elements products, the easy way to identify is to check the bounce when in contact with a flat surface. Genuine products do not bounce but are sturdy.

3. Characteristics of Rotex KTR rubber couplings

– Rotex shaft couplings are manufactured by KTR/Germany
– Very high hardness, maximum torque up to 56000 Nm.
– Couplings are made from high quality materials such as stainless steel (Rotex Inox), aluminum (Rotex ALU), cast iron (Rotex GG), ensuring durability and long life.
– Components used for engines with capacity over 1000 kW.
– KTR coupling rubber damping washers are designed in the shape of a star fruit
– KTR Rotex Standard couplings are available in various sizes: Rotex 19, Rotex 24, Rotex 28, Rotex 38, Rotex 42, Rotex 48, Rotex 55, Rotex 65, Rotex 75, Rotex 90, Rotex 100, Rotex 110, Rotex 125, Rotex 140, Rotex 160, Rotex 180.
Used in most types of machinery, hydraulic pumps, standard motors, general drive shafts and are trusted by factory engineers. However, applications include construction equipment and emergency power supply in hospitals, emphasizing the importance of custom Rotex coupling rubber (elastomer) solutions to ensure functionality and reliability.

4. Future trends in couplings

In the future, trends such as downsizing and the use of renewable fuels such as hydrogen will impact the use of rubber in couplings. Downsizing means that couplings must become more compact, while also creating higher temperature operating environments.
In addition, the transition to renewable fuels such as hydrogen also places higher dynamic demands on couplings. Coupling components must also be able to transmit higher dynamics from hydrogen-powered engines.
These trends all require the development and application of rubber in couplings to meet future performance and durability requirements.
