Stainless Steel Bobbins Type A

Rubber-metal bobbins with male stainless steel fixings, designed for vibration isolation in corrosive and demanding environments.

The AMC-MECANOCAUCHO® Stainless Steel Bobbins Type A are compact rubber-metal anti-vibration mounts designed to reduce the transmission of vibration and structure-borne noise between equipment and its supporting structure.

They consist of a cylindrical elastomer body vulcanised between two stainless steel metal plates fitted with male threaded studs. This simple and robust design provides an elastic connection whilst allowing easy installation on a wide range of equipment.

Depending on the installation, the elastomer can work in compression, shear or a combination of both, allowing the elastic behaviour of the mount to be adapted to the requirements of the application.

The use of stainless steel metal components provides excellent corrosion resistance, making these bobbins particularly suitable for marine environments, food-processing equipment, outdoor installations and industrial applications exposed to moisture or corrosive atmospheres.

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.
