Type C Bobbins

Cylindrical anti-vibration bobbins with female threads on both sides, offering a compact and versatile solution for vibration isolation of machinery and equipment.

The AMC-MECANOCAUCHO® Type C Bobbins are rubber-metal anti-vibration elements designed to provide a simple, compact and reliable flexible connection between equipment and its supporting structure.

They consist of a cylindrical elastomer body vulcanised between two parallel metal parts, each incorporating a female thread. This configuration allows bolted fixing from both sides and facilitates installation where external threaded studs are not required.

Depending on the installation arrangement, these bobbins can operate mainly in compression, shear or a combination of both, effectively reducing the transmission of vibration and structure-borne noise.

Available in a wide range of dimensions, rubber hardnesses and stiffnesses, Type C Bobbins are particularly suitable for engines, pumps, fans, compressors, electrical and electronic equipment and light industrial machinery.

Technical characteristics

Depending on the size of the rubber block, the AMC Mecanocaucho® bobbing has more or less elasticity, which is greater particularly in all directions perpendicular to its axis (shear). The AMC Mecanocaucho® bobbing thus makes it possible to make joins which permit major relative movements, up to several millimetres (in the case of heat expansion, chassis deformations, etc.). The AMC Mecanocaucho® bobbing serves very well for the vibration isolation of machines where the vibrations are perpendicular to their axis, unless these stresses are too much when applied in this direction.

Operation and Assembly

Its elasticity is much greater in all the directions parallel to the armatures than in the perpendicular direction. The rubber works based on compression or shear depending on the direction it is placed at installation time. This direction is made according to the use and the objective. It is therefore installed with nuts or screws depending on the model chosen, with one part attached to the fixed chassis and the other to the machine to be suspended.
