Industrial damping technology and Soft Close products exemplify the innovation and pioneering spirit of the Know-how Factory.

With the introduction of the High Energy series, the PowerStop industrial shock absorbers‘ commitment to quality has represented the highest standard in performance for over 20 years. Their proven features have been enhanced even further with the underlying optimization. The shock absorbers use an innovative, organic oil that can be used in the food industry with H1 certification and is even biodegradable. The highest in corrosion protection is achieved thanks to the use of stainless steel for the housing and piston rod. In addition, a new fixed stop with a longer piston rod guide length has been developed to increase the PowerStop’s well-known robustness even more. The product line is completed by an extensive range of accessories.

Calculate and select shock absorbers more quickly. Users receive a high-performance tool that allows them to make well-founded selection decisions quickly and combines calculation, selection guide and configurator functions in one tool.

Convenient calculation delivers fast results. A choice between a large number of different load cases appropriate to the case can be selected very easily.

Clearly arranged selection guide. The available dampers that meet these specifications are shown to the user in an overview table. The energy absorption for each damper is individually calculated in the table and its load is displayed.

Advanced search using a filter. Using filters, additional marginal conditions can be entered. These include especially high or low temperatures, use in the pressure chamber, contaminated environments or large angles for the impact of the load. The software returns suitable versions and necessary accessories or equipment options based on the selected filter.

Appealing solution, available as a mobile application. Since the calculation program is available online, customers do not have to install any software and can access it using any computer or laptop, as well as with any smartphone or tablet.

Industrial shock absorbers Powerstop

The series at a glance


  • Highest performance in a minimal space
  • Integrated oil volume reservoir
  • Increased guide length

Mini Energy – The slender

The Mini Energy provides a high rate of energy absorption when it comes to precision damping in miniature areas. Also installed in the cylinder for even greater space savings.


Standard Energy – The economical

The number one among standard dampers. Efficient damping at common energy absorption levels. This makes the Standard Energy series the winner in price/performance value.



  • Price/performance winner
  • Low-vibration damping thanks to spiral groove
  • Low counterforce

High Energy – The powerful

The high-end damper for the highest demands. Thanks to the spiral groove in combination with the pressure sleeve and the oil reserve, the High Energy series achieves a number of cycles that exceeds everything else on the market, with extreme energy absorption levels. All this with minimal space requirements.



  • For the highest demands and maximum energy absorption
  • Integrated oil reserve
  • Hardened and precision-ground guide
  • Cycle counts that outperform everything else on the market

Adjustable Energy – The adjustable

Can the High End series be surpassed? Yes, with the new adjustable series, the high energy absorption levels can be precisely adjusted to the entire stroke. Thus, the force is reduced and the damping is even softer.



  • Optimally adjustable damping across the entire stroke
  • Reduced supporting force — decreased load on the design
  • For the highest demands and maximum energy absorption
  • Hardened and precision-ground guide


  • TPC high-performance plastic: Thermoplastic elastomer on a copolyester basis High durability and resistance to media * No swelling, embrittlement or decomposition of the material, as is the case with rubber * Large temperature range
  • Special process for conditioning the material: High damping percentage and high energy absorption in the smallest space Reliable return behavior Increased service life in comparison to rubber pads
  • Design of the structure: Standard product portfolio with 3 series x 2 degrees of hardness Individual configuration for customized solutions possible
  • Expertise in design and production at Zimmer
  • Usability independent of velocity
  • 100% recyclable due to thermoplastic properties

* For chemical and media resistance see Damping technology catalog



  • The BasicStop profile dampers feature high-performance plastic and a specifically developed profile. It acquires its unique properties after receiving a special treatment. These properties allow it to absorb maximum amounts of energy even under the toughest conditions, while also achieving high damping rates.

Damping vs. springing

  • Conventional rubber pads only have a very small damping percentage and are more of a spring than a damper. Use of these pads hardly takes any kinetic energy from the system, which in turn can lead to damage to the system.
  • This is where the BasicStop brand profile dampers are setting new standards in the realm of material damping with their high damping percentage. Through the friction in the material, a large part of the kinetic energy is converted into heat, whereupon the structural damper returns to its original form (viscoelastic damping).
