Shock Absorbing Elements

Flexible and versatile RINGFEDER® Shock Absorbing Elements of the DEFORM plus® series are proving themselves in a wide range of industrial sectors as powerful damping units for enormously high energy absorption. They are made of high-quality, specially developed thermoplastics and, similar to the function of an airbag, convert kinetic energy into deformation energy in the event of an impact. In this way, they reliably protect important, cost-intensive machine, vehicle or building components from damage or even destruction without any major design effort. DEFORM plus® Shock Absorbing Elements are available in single use and reusable versions as well as in various standard and application-specific special variants. They are also completely free of wear and corrosion, have an extremely low weight and meet the highest environmental and safety standards.

I. SHOCK ABSORBING UNITS / DEFORM plus®

DEFORM plus® Shock Absorbing Elements are one-time use damping elements for high energy absorption. They transform kinetic energy caused by an impact into deformation energy. DEFORM plus® units have the following characteristics:

High damping properties (up to 95%)
Low costs
Small installation space
Easy replacement of used elements
Maintenance-free
No corrosion
Rectangular force-travel diagram
Versatility in design
A damping element consists of a thickwalled, Cylinder of high quality thermoplastic resin. On impact, it folds/shrinks to a discus-shaped structure.

Operating conditions
-25 up to + 50 °C
Resistant to lubricants
Resistant to hydrolysis
Almost equal properties under dynamic and quasi-static loads, force Fn raised factor at dynamic load fF ≈1 + 0,075 * v (m/s)
For outdoor applications we recommend the units to be coated or suitably protected against UV-rays
Plan thread generally in the unit, do not fix by a screw nut

II.SHOCK ABSORBING Elements DEFORM plus® R/RMP
Reusable buffer for absorption of kinetic energies without additional spring.

The casing combines the function of a spring and a damper. It can be reused after a dynamic load. Dependent on the velocity, the maximum supporting load automatically adapts to the impact energy, which means that i.e. equal masses are retarded more softly at lower velocities.

Working temperature: -10°C up to +50°C.

Ambient conditions:

The material is resistant to

Bleach liquor 3%
Sugar solution 30%
Hydrogen peroxide 10%
Ammonia 5%
Acetic acid 2%
Formic acid 2%
Linseed fatty acid
Tannic acid solution 20%
Lubrication grease and oil
A continuous contact with water should be avoided. In accordance with DIN 4012, building material class 2, the material is classified as non-combustible, dripping (off).
