Industrial Shock Absorbers – PowerStop 2 Series
Published on : Friday 01-10-2021
PowerStop industrial shock absorber family from Zimmer Group has already made a name for itself on the market thanks to its high energy absorption.
A Shock Absorber or Damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat), which is then dissipated. Most shock absorbers are a form of dashpot (a damper that resists motion via viscous friction).
The use of industrial shock absorbers significantly reduces shock and vibration to machinery. This eliminates machinery damage, minimises downtime, and maintenance costs while increasing machine life. Machines can be operated at higher speeds because industrial shock absorbers control or gently stop moving objects. Therefore, production rates can be increased. Harmful side effects of motion, such as noise, vibration, and damaging impacts, are moderated or eliminated, so the quality of production is improved. Therefore, tolerances and fits are easier to maintain.
Industrial Shock absorbers protect machinery and equipment operators by offering predictable, reliable, and controlled deceleration. They can also be designed to meet specified safety standards when required. Machines become more valuable because of increased productivity, longer life, lower maintenance costs, and safer operation.
You can use industrial shock absorbers for linear slides, swivel units, turn-tables, portable, and commercial appliances, factory floor machinery, automated machinery and equipment, tooling machines, machining centres Z-axes, impact panels, handling modules, robots and gantries, medical tables and many more.
Zimmer Group has been significantly advancing the development and mass production of standard components and damping systems for over fifteen years. We are trendsetters in the furniture industry due to our innovation and continuous developments. Other sectors also value the damping solutions we provide and used benefits for improving their machines.
The Know-how Factory produces pneumatic and hydraulic dampers of the highest quality. The Zimmer Group is the right partner for motion control in the industrial sector. Here, our innovative damping technology with its patented spiral groove technology ensures that kinetic energy is absorbed in the production process in a targeted manner, and wear is kept to a minimum.
PowerStop 2 series from Zimmer Group
A new series of industrial shock absorbers has two types: High Energy and Adjustable Energy. Both series give you a choice between a long stroke and normal stroke version when you want either powerful and short braking or a smoother damping process with slightly less lag.
Our PowerStop industrial shock absorber family has already made a name for itself on the market thanks to its high energy absorption even in small installation spaces. We have taken it to the next level by adding an extensive range of products and optimisations; we call it "PowerStop 2.0."
As of now, the series is available in four variants. It starts with the "Mini Energy" series, featuring the small M4 to M6 installation sizes. The "Standard Energy" base model follows these. This reflects the cost-efficient option at an established level of competition and available at an attractive price. "High energy," the third main series, currently represents the gold standard, featuring the highest energy absorption (in terms of installation space) on the market. Last but not least, we have the "Adjustable Energy" series with a High Energy adjustable damper, which covers the full velocity range from 0.1-5 m/s. Here, an extensive range of impact velocities can be quickly and variably adjusted to ensure optimal dampening for different amounts of mass or energy.
The Standard and High Energy series—already well established on the market—have been given extensive updates, with the range of thread sizes being expanded considerably. The Adjustable Energy series, on the other hand, is an entirely new range of products.
Both series (High Energy and Adjustable Energy) give you a choice between a long stroke and normal stroke version when you want either powerful and short braking or a smoother damping process with slightly less lag. Additionally, the Adjustable Energy series gives you the option of adjusting the shock absorber so that the entire stroke can be utilized to maximize damping smoothness. Compared to the existing series, the degrees of hardness have remained the same. However, the degree of hardness W (soft) has been significantly increased from the previous impact velocity of 1.8 to 4 m/s up to an impact velocity of 3 to 5 m/s.
For decades, the Zimmer Group name has been synonymous with extremely high product quality and durability. As such, the entire PowerStop family includes a housing and a piston rod made of high-grade stainless steel. This ensures extremely high corrosion protection. Foreign particles cannot adhere to the housing, and cleaning is easy.
The optimised dampers now come standard with a range of protection classes that were previously only available upon request for a wide variety of dirty environments. In addition to the damper without protection for clean assembly environments, the customer can select, for example, a damper with a felt ring that is resistant to dust and chips and can be used in applications such as wood processing. As an alternative, a product with a wiper is available. It is suitable for use in conjunction with liquids and hydraulic media, among other things. However, the version with a bellow offers the best possible protection. This version does not allow anything to ingress into the damper or escape from it. The application areas include operation in particularly dirty environments such as in grinding machines (abrasive media) or applications exposed to cooling lubricants under pressure. However, areas of application also include very clean environments such as in food or cleanroom applications. The TPC material from the Basic Stop damper series is used as an extremely durable protective cover. This material has been tried and tested and is known for being extremely tough and media-resistant.
In the beginning, the series is available in the M4-36 thread sizes and will later be expanded by adding M45 + M64 threads. Aside from the extensive product expansion, accessories have also been added. Alongside currently available accessories, a sensor stop sleeve is now available for detecting or determining the moving component's final position. This makes it possible to boost performance by reducing the cycle time.
Apart from the clamping flange that can be screwed on from above, another new feature is a clamping flange that can be screwed on in the direction of the industrial shock absorber. It is very flat, which makes it easier to attach using commercially available screws, especially at large thread diameters.
We offer a side load adapter in standard and long stroke versions. A felt ring or wiper option is available for absorbing lateral forces during rotative damping processes. We offer a pressure chamber seal, which is used for sealing when the damper is installed in a swivel unit or a pneumatic cylinder.
Four new thread pitches have been added to the series as additional features, and an innovative biologically-based oil with H1 food-grade certification is now being used with all dampers.
As a result, the stainless steel shock absorber is now also suitable for use as a standard product in cleanrooms or in the food industry.
Product benefits at a glance

2. User-configurable series with significant additions accessories
3. Integrated fixed stop, especially with Adjustable Energy, an external fixed stop is not necessary. Max force in the end position is specified in the catalogue.
4. Protection against liquids or dust and chips as standard option ideal pricing on customer requirements possible. Flexibility to adapt the damper to the surrounding condition. Four different protection versions (adapted to the environment)
5. Four new (thread) sizes. Adapted long-stroke versions. Same energy consumption as normal stroke -> smoother damping. Expansion to sizes M14 and M16
6. The highest energy absorption at the lowest space requirement is achieved thanks to optimal utilisation in every piston position.
7. New configurable Adjustable Energy series + fixed stop
8. The fine adjustment of the damper ensures optimum damping throughout the stroke and up to the fixed stop.
