Bobbin – Annular

Bobbins are devices for making elastic anchorings or fixings. They can be used in a wide variety of applications, particularly for elastic suspensions and anti vibration isolation of machines and different mechanical organs. They are made of a block of rubber with two parallel metal parts at the end which enable it to be fixed either by screws in the ‘’C’’ model or with nuts in the ‘’A” model or a combination of both in the ‘’B” model.

Product Description

Depending on the size of the rubber block, the Annular bobbin has more or less elasticity, which is greater particularly in all directions perpendicular to its axis (shear). The Annular bobbin thus makes it possible to make joins which permit major relative movements, up to several millimeters (in the case of heat expansion, chassis deformations, etc.). The bobbin 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.

Bobbins are particularly suitable for installation on small motor-pumps, motor-ventilators, driers, sieves, compactors, washing machines, electrical motors, on-board control panels, measuring apparatuses, control cabinets, microphones, fluorescent tubes, etc.

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.

Male threaded mounts on both ends.
