The innovative TUBUS profile dampers are a very cost-effective alternative for emergency stop applications.
They are produced from a special Co-Polyester Elastomer. They constantly decrease energies in areas in which other materials would fail. The excellent damping characteristics are achieved through the material and the worldwide patented construction design.
The profile dampers are versatile and are designed to absorb the rising energy with a degressive (TA-series), almost linear (TS-series) or progressive (TR-series) characteristic. The TUBUS-series comprises five main types with almost
80 individual models.

The design of JARRET Industrial Shock Absorbers utilizes the unique compression and shear characteristics of specially formulated silicone elastomers.
These characteristics allow the energy absorption and return spring functions to be combined into a single unit without the need for an additional gas or mechanical spring stroke return mechanism. |
|
| The AA series has been designed for loads from 10 to 6000 daN. One of its most important feature is the multidirectional reaction which guarantees an optimal response along all directions. Its high safety level prevents the detachment of the appliances even if the elastomers should be completely destroyed. It can be fixed either with two or four bolts. |

As a result of its interlocking loop construction-which couples resiliency with high damping characteristics and nonlinear spring rates-Metex knitted wire mesh offers unique properties for absorbing shock and vibration. Each loop acts as a small spring when subjected to compressive loads, and will immediately resume 90% of its original shape when the load is removed.
Knitted wire mesh can be used to provide mechanical support for the monolith element used in an exhaust system's catalytic converter. The wire mesh is used to support the monolith, compensate for the wide range of thermal expansion rates and protect the fragile ceramic honeycomb from the mechanical shocks associated with various driving conditions. |

Limits based on damping direction. Force always relates to the net load which is pushing or pulling on the dashpot. Typically, force will dictate the unit’s size when the Airpot is used in the dashpot configuration (as opposed to snubber configurations where energy is the primary factor).
At rest, the dashpot is a passive device and has no force output. In motion, the dashpot offers a resisting force which rises to equal the force of the input load, achieving a zero net force. This results in zero acceleration and constant velocity.
Force limits of Airpot dashpots are determined by the direction of damping and the diameter of the piston.
In pull damping units, a vacuum is being created in the dashpot as the piston moves outward. Thus, the maximum resisting force limit of the unit is a direct function of atmospheric pressure and the area of the piston (F=PA).
Assuming an equal ambient pressure, larger diameter units will have force limits higher than smaller diameter units; the limits being directly proportional to their piston areas. (Model force limits are summarized in the specifications section.)
In the push damping (compression) direction, air must be compressed into an ever decreasing space; the force can rise to a level which is higher than is possible in the pull damping direction. Therefore, it is possible for a smaller diameter push damping unit to achieve greater resisting forces than a larger diameter pull damping unit. However, stroke lost to compression should be taken into consideration |

GMT air springs provide for a low-frequency elstic set-up of machinery, aggregates, conveyors, vibration generators and high-speed presses thanks to their vibration insulation, shock absorption and structurborne noise insulation.
Technical data:
- natural frequency, depending on load about 3-5 Hz
- assembly by way of scews connection at the part on
bearings
- levelling by way of compressed air +/- 10mm of installed
height through a standard tire valve |

NV800 air springs are ideal for supporting high sensitive experiments, machines and equipment.
These isolators can be used in a wide range of load because of their unique design.
The characteristic attributes remain in narrow limits and do not underlie a strong load dependence like comparable products do. Consequently the NV800 are ideal for storing equipment with asymmetric load distribution. In addition the broad load range serves for future upgrades which is common in scientific equipment.
The use of an extreme thin membrane makes the NV800 behave almost like an ideal air spring in the vertical direction. The resonance frequency is about 1,5 Hz. In case of horizontal disturbances an inverse pendulum which is installed inside the chamber offers excellent isolation features with a resonance frequency as low as 1,3 Hz.
NV800 air-springs are inherently safe and designed for lowmaintenance. Integrated limit stops prevent any overload condition. After having installed it once no more adjustments are necessary.
A complete set contains three or rather four NV800 air-springs as well as the needed number of height controllers HR2. In the normal case not more than three height controllers HR2 are needed for additional NV800 isolators. |

NV 50 is an isolator for integration into platforms with attachment options on one side wall or at the bottom. The is fixed with the centrical load rod. In consequence of the prismatic basic shape these isolators can be integrated in substructures of vibration-sensitive instruments and are ideal to use as OEM-elements.
If an installation in the inside of the instrument is not possible the dampers can be masked with an optional available blind made of polished stainless steel. The NV 50 hold brilliant isolation features in the lower frequency range despite the low contruction volume of about one liter.
The resonance frequency lies horizontal under 2 Hz and vertical at 2 Hz. The levelling range is +/- 3mm and can be set up with the height controllers HR2. A permanent supply of compressed-air is necessary. |
|
The NV150 air-springs are the pneumatic isolators for the cplusw damping tables and are inserted into their base frame.
But as an OEM-product the NV150 can be used in many ways. Because of an upper stopper of the piston the design offers a maximum safety against an accidentally compression overload.
A permanent supply of compressed air is necessary for operation as well as a compression or rather a height controller for setting up the working height in between the levelling range of +/- 4mm The resonance frequency is about 1,7 Hz in horizontal directions and in vertical direction under 2,5 Hz.
CplusW offers support for system integration into customer products or special applications. Sets composed of three, four or even more NV150 air-springs will be delivered with the necessary number of height controllers HR2.
NV150 systems do not need any special maintanance after the initial setup. |

| Enidine's Rotary Viscous Dampers (RVD) provide smooth control in applications that require continuous or intermittent positioning, forward, reverse and fixed path motion. The RVD design combines low breakout friction with viscous damping to control bi-directional rotary motion in applications such as door hinges, rollers and access panels. Each RVD contains a solid, rotating element called a "rotor". This rotor is surrounded by a thick film of silicone fluid and sealed inside a stationary housing. The RVD's rotor provides resistance by shearing the silicone fluid, controlling the desired motion. |

Vibration dampers are different elements to connect two units or to install one unit into a system.
The design of these vibration dampers is a result of the development considering the space, the technical characteristics and requirements (load, frequencies, amplitudes, max load, etc.) as well as the surrounding conditions.

Pumps may rotate or reciprocate. Rotating pumps are usually well balanced. Nevertheless their elastic support makes sense when these pumps are installed on the upper floor levels inside a building, since in this way vibration and structure borne noise can be avoided.
