Giubo Couplings

Giubo Couplings are resilient in the direction of rotation and can run at an angle and will allow both acial and radial displacement. They are thus the ideal connecting element for all drives which are running uneven, prone to shock loading, and in which damaging peak torques or rotary vibrations have to be smoothed out; the choice of various “Shore hardness grades” for the “Giubo ring” allows for different damping characteristics.

Normally the high resilience coupling ring consists of natural rubber with a hardness of 65 Shore A; this operates reliably in the range between -25°C and 70°C. The use of the Giubo Coupling is not limited to applications in the Automotive Sector, it is also used in general machinery as well as the areas of construction, transportation, electric drives, power generators or connect to conveyor and centrifugal pumps.

Four properties that particularly characterize the GOETZE-Giubo coupling and therefore secure her a prominent place in the design of power transmission systems:

1. Torsionally flexible:

2. Lengthwise flexible:

3. Angularly movable:

4. Sidelong movable:

Materials: Giubo coupling elements are made of natural rubber in several hardnesses, such as 50,55,60,65,70 and 75 Shore A. For special cases elastomers are made of materials on the base of chlorophene. To solve your drive problems, our technical support will be happy to help.
