Hollow springs series M

Hollow springs are, among other things, used for supporting and structure-borne noise insulation in equipment manufacture and technology. They have vibration-insulating as well as shock-absorbing characteristics, which are also used in many different ways in the fields of vehicle construction and mechanical engineering. The range of applications for these spring elements are, for example, skid or landing gear springing in aircraft construction, in whirlers and jolters, for the separation of vibrating masses, as a shock protector in vehicle construction, or as an ejector in blanking coining and punching dies. The elements are attached and secured with liners and/or flanges. All these products are maintenance-free.

Cap elements

Cap Elements

Gummimetall® Cap elements are multi-directional buffers, characterized in particular by extremely long spring excursions and excellent shock insulation. The special shape of the cap elements facilitates sound and vibration insulation of machines and aggregates with a low excitation frequency. The components are suitable for active and passive insulation of machines and aggregates as well as for the bedding of containers on ships and vehicles. The identical stiffness properties in x- and y- directions prevent lateral sliding under stress. The cap elements are generally made from natural rubber. If required, special elastomers can be used to ensure the optimal and problem-oriented application of the high-capacity support.

Collars

Collars series 7

Gummimetall® Collars are structured to be particularly suitable for isolation from active and passive vibrations of bolts, fixing screws, or other through connections. The rubber part is vulcanized between a flat disk and a shaped collar disk, both in steel. The task of the two metal parts is also as a centered support of the bolt or screw, to avoid direct contact with the rigid parts to be insulated (e.g. the machine foot).

Buffer

Bushes

Gummimetall® bushes are structural elements, in which an outer and an inner precision sleeve are firmly held together with a layer of vulcanized elastomer. The cylindrical liners dampen axial as well as radial movements and are able to absorb torsional movements as well as cardanic deflections. For a dynamic application, the values must be reduced to approx. 50%. For cardanic applications, it must be noted that the elastomer layer between the liners may be pressed together by 1/6 of the rubber’s thickness. During installation, it must be ensured that the assembly forces are not applied continuously through the elastomer.

V-w-x-y-z isolators

Series V W X Y Z

Gummimetall® "V-W-X-Y-Z" elements have particularly sensitive vibration dampers for active and passive isolation of delicate instruments. The differentiated forms make possible various choices, also in relation to assembly needs.

Spring washers series DE

Gummimetall® Spring washers consist of an inner and an outer metal ring, which are held together by means of a layer of elastomer firmly vulcanized into the gap. They are suitable for use in torque converter bearings, for buffering pendulum supports, leaf spring ends, as well as for tension and shock devices.

Spherical ball joints

Spherical ball joints

Gummimetall® Spherical ball joints are structural elements whose inner ball is firmly connected to the outer metal by means of a vulcanized elastomer layer. Such joints are designed for multi-directional torsional loads and, thus, ideal as vibration-technological components for joints and connecting rods. One advantage is the fact that all movements can be achieved without any lubricants. the spherical ball joints can be made up of an inner pin / through-hole as well as of an outer socket consisting of one or several segments.

Chevron

Gummimetall® Axle springs are multi-purpose vibration-reducing elements. The individual metals are firmly held together with vulcanized layers of elastomers. Due to their simple installation and long lifespan, axle springs are ideal for use in all types of rail vehicles. By selecting the angles and the number of intermediate spring links as well as the angles of the axle bearings to each other, three different spring stiffness can be produced, depending on the direction. Furthermore, selecting the geometric dimensions of the individual layers and the corresponding rubber quality can also vary the degree of stiffness.

Rubber blocks

Rubber blocks

Gummimetall® Rubber blocks are used for structure-borne noise insulation, for example in wheels of rail vehicles, funicular railways or bearings of roller tables. They have vibration-insulating as well as shock-absorbing characteristics, which, referring to use in LRV-wheels, lead to a decrease in the level of noise and an improvement in passenger comfort. A further advantage of using rubber blocks lies in the increased life span of the chassis, since, compared to rigid bearings, there is a reduction of shock loads and a decrease in abrasive wear and tear.

Cone springs

Cone Spring

Gummimetall® Cone springs are used in body manufacturing for the bedding and suspension of the engine in the chassis frame. Being vibration insulators and dampers, cone springs allow for relatively considerable spring excursion and have a progressive, characteristic curve. Buffers also help to absorb shock loads without causing irreparable damage to the part. If different degrees of stiffness are required in X and Y directions, use models with kidney-shaped recesses.

Roller Spring

Gummimetall® Roller-springs are vibration-damping elements consisting of a rubber ring, a tapering metal pin and a metal housing. Their metal parts and the rubber ring are not bonded together by vulcanisation. Roller-springs are used for damping vibrations in rail vehicles. The characteristics of roller-springs can be varied as required, within their permissible capacity.

Bolster springs

Bolster Spring

Gummimetall® Bolster springs are used for high-pressure loads. Therefore, they are especially ideal for the bedding of stone crushers, tandem axles, and dollies. For these purposes, oil and age-resistant elastomers are used.  As a rule, these bearings are built in pairs, as you can see from the assembly diagram.

Compund springs

Compound Springs

Gummimetall® Compound springs can be used in many different ways for the purpose of active and passive structure-borne noise and vibration insulation. These parts can withstand high-pressure loads. They can be used, for example, as center bearings or as bearings for jolters and sifting machinery.

Multilayer springs

Multilayer Springs

Gummimetall® Multilayer springs are damping elements for many different applications. Their different metals have been firmly bonded by way of vulcanized Elastomer layers. Multilayer springs are especially ideal for absorbing large pressure loads. These springs are used, for example, in lorries, trucks, buses, railway vehicles, coal mining and concrete machines. It is possible to protect multilayer springs against sudden tensile loads by making them tear-proof – by fitting them with chain links, firmly integrated by means of vulcanization.
