norelem moves – 26000
The norelem product group 26000 comprises seven categories:
- Compression springs
- Elastomer buffers
- Rubber buffers
- Damping plates
- Profile dampers
- Gas springs
- Shock absorbers
Compression springs
norelem compression springs consist of a rectangular profile wire made of chrome-silicon steel. They are also known as helical springs and are wound in such a way that the springs react to pressure.
The compression springs come in diameters of 10-25 mm and lengths of 25-305 mm. They can be used up to an operating temperature of 230°C. The special profile of norelem compression springs enables extremely high alternating and continuous loads.
There are four different compression springs in the range. The individual helical springs are divided into four colour groups. The spring type is determined by the force required.
Green – is used for light loads
Blue – for medium loads
Red – for heavy loads and
Yellow – for particularly heavy loads
The characteristics of the compression springs, such as the length, diameter, force and colour of the springs, all comply with ISO 10243. Among other things, this standard specifies the installation dimensions and tolerances of compression springs with a rectangular cross-section.
Every compression spring, from green to yellow, is available in the same lengths and diameters. This enables easy replacement, even if a different load stage is required.
In addition to use in toolmaking and mechanical engineering, compression springs are also used in fixture construction. Thanks to their versatility, compression springs are commonplace in industry. Basically, however, they are used when a machine part needs to be moved.
Elastomer buffers
Elastomer buffers insulate and dampen airborne and structure-borne noise. They are therefore used to cushion moving bodies and serve to isolate vibration generators. They are characterised by high mechanical load capacity and long service life. Even with a hard setting, elastomer buffers boast high resilience to shock.
As they are maintenance-free, elastomer buffers are, above all, economical!
In addition to the advantages named above, it should also be mentioned that elastomer buffers do no rupture, even when heavily overloaded. This contributes to the protection of people and machines.
Resistance to oils and greases rounds off the profile of elastomer buffers. Elastomer buffers from norelem meet all quality requirements from DIN ISO 10069-1.
The norelem range contains the following versions of elastomer buffers:
Rubber buffers
Rubber buffers are damping elements. They are among the most common construction and standard elements for elastic bearings in industry, and used in a wide variety of fields. The buffers dampen and cushion vibrations in machinery and absorb kinetic energy.
The rubber buffers from norelem are distinguished by their excellent shock absorption and cushioning as well as their robustness.
This is particularly beneficial in the case of repeated impacts and accelerations with an end stop.
The following should be taken into account when selecting a suitable rubber buffer:
Rubber buffers are less resilient under shear loads than under pressure loads.
norelem offers rubber buffers in various hardness grades. Natural rubber in combination with steel or stainless steel ensures reliable damping and durability.
norelem offers rubber buffers with internal or external thread to suit your installation requirements. It categorises the various rubber buffers according to “rubber buffer types”. This indicates the possible applications of the rubber buffer with its thread in machine construction or industry.
The range contains the following rubber buffers:
- The rubber buffers in product group Type A have an external thread on both sides.
- Type B rubber buffers have an internal thread on one end and an external thread on the other.
- Rubber buffers in product group Type C have an internal thread at each end.
- The rubber buffers Type D have an external thread and a natural rubber overlay on the visible surface to limit the spring deflection of moving bodies.
- The Type E rubber buffer differs from the Type D buffer only in that it has an internal thread.
Damping plates
Damping plates are used to reduce individual shock loads. In other words, where vibration occurs and needs to be absorbed as quickly as possible.
norelem damping plates are made of cellular polyether-urethane. This material enables the damping plates to withstand shock loads and absorb continuous loads effectively.
The plates are mounted by simple gluing. The damping surface area can thus be enlarged by placing a number of damping plates side by side. If the surface area is then too large, the damping plates can be machined afterwards to adjust their dimensions.
The density of the damping plates is differentiated by colour. The individual colours have the following meaning:
- Red = soft (density 165 kg/m³)
- Green = medium (density 460 kg/m³)
- Bordeaux = hard (density 1000 kg/m³)
Profile dampers
Profile dampers from norelem are a type of vibration damper used to reduce vibrations and noise in machine and systems. They are mounted on the connecting points between machine parts or system components to reduce the transmission of vibrations and noise. These profile dampers are made of an elastic material that absorbs the energy of the vibration and thus prevents it from being transmitted to other parts of the system.
Profile dampers are an important element in the mechanical engineering industry as they extend the service life of machines through this absorption.
Profile dampers from norelem are specially developed to meet the requirements of the mechanical engineering industry. They are made of high-quality materials and offer a long service life as well as high resistance to vibrations and oscillations. In addition, they are easy to install and can be adapted to different types of machine elements.
The range contains the following versions:
Gas springs
Gas springs control, brake and move bodies without great effort. They are used in construction technology for damped movements (opening, closing and adjusting) of hatches, lids or covers. High corrosion resistance and low maintenance make gas springs a very convenient solution for design engineers. Gas springs are used in areas such as machine and plant engineering and fixture construction. They can also be found in the furniture industry, in household appliances, sports equipment and in the automotive industry.
Gas springs from norelem are filled with nitrogen and oil and can withstand operating temperatures from -20°C to +80°C.
The stainless steel version of the gas springs contains oil that fulfils FDA regulation 21 CFR 178.3570. This means that our stainless steel gas springs can also be used in the food processing industry.
Shock absorbers
The shock absorbers brake moving bodies quickly and gently. They are therefore suitable for use in handling devices, turn & swivel units, linear cylinders, and many other industrial applications, especially automation. Shock absorbers are mainly used in machines and systems to dampen movements and reduce vibrations. They can also be used to extend the service life of machines and systems by reducing the load on components.
Shock absorbers work by the basic physical principle of energy conservation. They absorb the energy of a body and convert the kinetic energy into heat with the help of friction (the internal oil flow). The resultant thermal energy is transferred to the cylinder body in the shock absorber and dissipated to the environment.
norelem shock absorbers are available in various sizes and versions and can be used for a wide range of applications.
norelem offers shock absorbers made of steel or stainless steel, which are also suitable for temperature ranges between -50°C and +120°C.
