AIR SPRINGS
Air springs have been among the core competences since the establishment of CFM Schiller in 1978.
This type of springs with low natural frequencies primarily serves as a high-quality active vibration isolation of dynamic test rigs as well as a passive support for sensitive plants, machines and measuring devices. We continuously enhance and develop our air springs and the corresponding control systems. CFM Schiller specializes in customized solutions for extraordinary applications.
CFM Air Springs are high-quality products that have been proven and time-tested for many years. We design, manufacture, and professionally install the air springs into the desired application. Under normal operating conditions, the service life of our air springs exceeds 25 years.
The housings and pressure plates are made of aluminium or steel, depending on the series and type of the air spring. All rubber components for the air springs are exclusively made from highest grade elastomers with wire reinforcing. In combination with our decades of experience in manufacturing air springs, CFM Schiller can guarantee an enormous service life.
All CFM Air Springs are specially designed for applications in the field of vibration isolation. Every type of air spring has its specific operation purpose and characteristics.
We are looking forward to providing advice to you regarding the right choice of vibration isolation for your specific application.
STEEL SPRINGS
Steel spring isolators are spring elements which basically
consist of a case and stacks of
compression springs.
They are mainly used for the bearing
of machines, such as presses,
forging hammers and coal mills.
Their natural frequencies
are greater than 3 Hz.The viscous damper plays a key role in the successful vibration isolation. The natural frequencies of our steel spring isolators range from 1.5 Hz to 6.1 Hz, depending on the type.
ELASTOMER ELEMENTS
Elastomer elements from CFM Schiller are suited as vibration isolation elements, when the excitation frequencies are above 12 Hz (720 min-1). When applied properly, they effectively minimize vibrations and structure-borne sound. Elastomer springs are easy to install and feature a very high internal damping. CFM Schiller calculates and provides elastomer elements that perfectly suit your individual application.
Versions:
ELASTOMER SPRINGS- ROUND
Round elastomer springs are the ideal solution for elastic support of small to medium masses in all areas of machine, equipment, and engine design. Various sizes and versions are available with different connection interfaces to provide design freedom for diverse applications.
Fields of Application:
- Versatile standard elastomer springs for regular requirements.
- For heavy applications with little available space.
-
For anchorage-free installation of machines with low excitation forces.
RUBBER METAL BARS
Rubber metal bars are particularly suited as elastic support of heavy and extremely heavy machinery, equipment, and foundations. A practice-oriented range of products and sizes offers individual solutions. The length of the bars can be customized according to the applied loads. Rubber metal bars are the ideal elements for support systems with different loads on the individual supporting points.
Fields of Application:
- Universal support elements for very large masses. Adaption to load through chosen length of bar.
Therefore suitable for supports with asymmetric position of center of mass.
- Medium vertical natural frequencies with very good lateral stability.
