Metal Frame

The RK pipe connection system that has been established for decades is being constantly developed and is at any time at the forefront of pipe connection technology. The most comprehensive way of interconnecting pipes is screwing them together using the new RK Industrie Design pipe connection system. Users appreciate its fatigue strength and economic efficiency as well as the advantages of simple and fast assembly/disassembly. For the most varied fields of application, we provide a range of connecting elements made from aluminium (elements made by gravity die casting and extrusion moulding), plastics, steel and stainless steel. The simplicity and logic of pipe connection technology led prematurely to developments for the linear units of the series E and EP. The RK pipe connection system is used here as a carriage and a fixation element. The industrial staircase and working platform system (ITAS) combines pipe internal clamping elements and aluminium profile technology to a unique system and is an example for RK Rose+Krieger’s thoughts on compatibility.

Metal Frame 2

Whether guiding, adjusting, positioning or moving uniformly, the demands on linear motion sequences are as varied as the available solutions. We offer a broad spectrum of linear movement components: from the occasional manual adjustment, through to frequent movements and highly dynamic positioning in continuous operation. And to help you select the most suitable range of products for your requirements quickly and easily, we have developed a system that is strictly application oriented. Within the selected range you can then determine the ideal size and model based on your performance requirements.

Eichenberger Gewinde AG

eichenberger logo

Eichenberger develop, produce and market innovative linear power transmission products including ball screws with rolled threads designed specifically to address the needs of potential OEM applications.

Linear power transmission technology range

  • Carry ball screws
  • Carry Speedline high-helix ball screws
  • Speedy high-helix lead screws
  • Rondo round thread lead screws

Thread rolling is the core expertise of Eichenberger Gewinde AG. Not surprisingly, we utilize this process to form the thread profiles of all the screws we produce.

Even though all Eichenberger lead screws are made using the rational thread rolling process, individual model series feature distinct differences in design and performance. Product characteristics therefore need to be considered when selecting the right product.

The Exlar Advantage


Understanding the Difference

The Need for an Alternative – Electric Actuation

In an industrial world very familiar with fluid power systems, Exlar anticipated the need to develop an alternative actuation method to the existing hydraulic and pneumatic cylinders. The new product would need to offer improved positioning performance, eliminate fluid leaks, and provide energy efficiencies, all while maintaining the robustness and reliability of hydraulics and pneumatics.

Hydraulic cylinders, while robust and reliable, rely on pressurized oil and require significant maintenance to achieve consistent levels of positioning accuracy. Fluid leaks are common, causing both end-product and environmental contamination. Exlar’s goal was to make improvements to the accuracy, environmental, and maintenance issues. As seen in the comparative table, pneumatics also have advantages to offer, but do not provide a viable solution where positioning, stiffness or accuracy are required.

Industry was ready for a cleaner, more efficient and more accurate solution to these existing technologies.

The Logic of “All-Electric” Solutions

Since electrical power is readily available and is in fact used to create the fluid power, it seemed logical to find a solution which relied exclusively on electric power. This would eliminate the primary source of inefficiency which is the conversion of electrical power to fluid power first, and then to the desired mechanical motion. Additionally, an all-electric solution would be easier to control since control systems universally depend on electric signals to monitor and control position.

As the search began, it was discovered that many engineers had already been replacing fluid power actuators with electric servo systems. The results were favorable wherever the desired motion was in the form of rotation. A major obstacle remained, however, when linear motion was required, particularly when one wanted to substitute an electric actuator directly for a hydraulic or pneumatic cylinder. There seemed to be no existing electric counterpart with similar form factor and size and which exhibited the robustness and long life of such devices. Not until, that is, Exlar proceeded to identify and characterize the available technologies for creating linear motion.

Understanding these choices along with their advantages and disadvantages is key for the engineer designing a machine utilizing linear motion.

Omet – Systems in Motion

omet logo

OMET linear motion proposes three ranges of complete modules aiming at satisfying the most varied needs in the field of linear motion. From the most economic to the most performing one, everything is to be evaluated according to the application.

The system is composed of a pivot-pin cursor (adjustable central pin) sliding inside a C-shaped rail with inner sliding rails.

The prominent features common to all ranges are:


All the rails are provided with fastening holes so that the assembler does not have to make any further operation. If the application requires supplementary holes on the rail, a special “reference groove” allows the point self-centering.


Omet 1

The rails have sliding races in internal position and are therefore protected by accidental external impacts. The coupling cursor-rail has a very compact design. The rails and cursors are in aluminium alloy, which confers the system extreme lightness.

In the case of the models T,6002,…. e T,6003,…. , the rails are made by coupling a supporting element in aluminum alloy with hardened and ground steel bars that make up the sliding surfa- ce. The aluminum extruded profiles are stabilized and anodized.
