Specification

To prevent transmission of vibrations (e.g. machine vibrations to anchoring)

Elasticated support

Made of natural rubber, especially suited for supporting light- and medium-weight systems without extensive dynamic loading

Cradle to Cradle^®-certified

Upgrading the building using non-hazardous materials

Wider range of applications for GreenBuilding and building certification in accordance with LEED^®, BREEAM^® and DGNB

Our products with the Cradle to Cradle Certified® certificate are resource-conserving and low-polluting. The standard assesses the safety, recyclability and pollutant content of materials in the end product. The special focus here is on conserving resources, e.g. by using recycled material in the manufacturing process.

Notice

The majority of rubber/metal elements are intended for pressurised loads. Installation positions where tensile and shear stresses are dominant should be avoided.

Not suitable for petrol, benzene, solvents, oils, greases and acids

Application

Application area

They are especially suited for supporting light and medium-weight systems without extensive dynamic loading.

Positioning or support of ventilators, air-conditioning units and pumps

As support feet for compressors, fitness equipment and other frames and machines
