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
  • Low weight
  • 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

Applications of the patented DEFORM plus® units include

  • Tool manufacturing
  • Wind driven turbines
  • Construction of vehicles
  • Mechanical engineering
