Guides in machine construction from norelem
The norelem linear systems and linear guides are divided into product groups of carriage guides, positioning systems, motorised positioning table systems, plastic slide guides, roller guide rails, profile guide rails, linear ball bearings, linear guide systems, position indicator scales and level vials.
Linear systems
Linear technology, as a technical sub-discipline of drive technology, deals with the question of how mechanical components can be moved translationally with as little friction as possible. A linear system should be able to absorb the highest possible lateral forces without deforming.
Linear systems from norelem are used in semiconductor production, robotics, the packaging industry and medical technology. The main area of application is certainly factory automation. Linear systems provide customised solutions for positioning, gripping, lifting or rotating production elements. The systems are designed and installed to suit the respective area of application.
Watch the norelem ACADAMY video to find out what linear technology is, what it is used for and what influences the selection of linear technology elements. You will learn what damage can occur to elements and what countermeasures you can take.
Linear guide
A linear guide, often also called a linear guide system, can be divided into two main categories:
Slide guides are linear guides in which the individual elements of the linear guide are not separated by rolling elements. These guide systems include, for example, the dovetail slide from norelem, which prevents the guide element from lifting during rotational movements.
Rolling guides are based on the principle of circulation. Rolling elements, such as rollers or balls, are circulated between two moving elements. A rolling element cage, such as a roller chain, keeps the rolling elements in check and ensures that the guide runs as smoothly as possible. Rolling guides include, for example, profile guide rails or linear ball bearings.
In general: the form and positional accuracy of a guide are later the crucial parameters with regard to the quality of the guide.
Linear ball bearings from norelem
Linear ball bearings – also known as ball bearing bushes or shaft guides – use linear motion to guide a machine element along a cylindrical shaft with as little friction as possible. In contrast to conventional ball bearings, they therefore also have axial ball recirculation.
The norelem ball bearings comply with ISO 10285 series 3, which regulates the main dimensions and tolerances of linear ball bearings.
Application
The linear ball bearings are used in machine and fixture construction and in industry whenever only limited installation space is available.
Linear bearings are important components for machine and fixture construction and are used in automatic production machines, machine tools, rail vehicles as well as in foodstuff and medical technology.
The norelem linear ball bearings are used, for example, in printing machines, flame-cutting machines, all types of presses and also in computers and measuring equipment. Linear bearings are also used for the construction of sliding devices such as linear tables. The norelem linear plain bearing is also used in food, pharmaceutical, medical and chemical applications.
Guide rails with carriage
Carriage guides from norelem enable positioning and movement in horizontal and vertical directions. The carriage guides can be flexibly adapted to different requirements and are therefore the ideal choice for a wide range of applications in machine and fixture construction such as measuring and control technology.
Area of use of carriage guides
Due to their high precision, carriage guides are very popular in the fine mechanics industry, for applications in machine, fixture and metrology equipment and optical construction. For example, the micrometer spindle can be used to precisely adjust products and secure them in a desired position.
Materials used for carriage guides
Grey cast iron and aluminium are used as materials for the carriage guides, with the aluminium versions representing an excellent compromise between weight, load capacity and precision. Optionally the carriage guides are available with end stops and micrometer spindles.

Linear guides from norelem
Linear housing units perform linear movements and can act as transport carriages. The compact models from norelem are made up of an aluminium housing and a pre-installed linear ball bearing with a seal on either side. There is also a tandem version available, which has two pre-installed self-aligning linear ball bearings. Each housing unit has a lubrication hole, through which the ball bearings can be re-lubricated if necessary.
Last but not least, the norelem range includes shaft supports in a compact design. They have a location hole which allows easy and secure clamping and fastening of the guide shafts.
Profile guide rails
Profile guide systems from norelem are primarily used for material feed systems, assembly and automation engineering.
norelem profile guide rails made from steel are fitted with inductive, hardened and ground tracks. These are arranged at an angle of 45°. Rows of balls distribute the loads evenly. The system can therefore absorb high loads from all sides. Thanks to an intelligent, built-in lubrication technique, the profile guide systems running on rails are extremely low maintenance and are designed for uninterrupted operation at temperatures of up to 80°C.
The profile guide rails can be screwed on from above and are available in four different sizes. The longitudinal length can be cut according to customer requirements (max. up to 3690 mm). Depending on requirements and the space available, four different carriage versions (from standard to compact) are available made from carbon steel with frictional steel ball bearings. The standard carriages are available with recirculating ball guides precision N not preloaded (Z0). Higher levels of accuracy and pre-stressing can be provided on request. The norelem profile guide systems correspond to the market standard and can easily replace linear guides of the same design by other manufacturers.
Roller guide rails from norelem
Be it in toolmaking and machine construction – particularly in the development of intelligent handling and automation solutions – in warehouse and transport logistics, or in medical technology: roller guide and telescopic rail systems from norelem are used in a wide range of applications and offer a variety of possible solutions for the alignment of two-track parallel guide systems.
Areas of use of norelem roller guide systems
The roller guide systems from norelem are always used when parts, segments of machines or plants have to be moved along a linear axis for operational, production or logistic reasons. In comparison to standard steel rails, these higher-quality roller guide rails from norelem made from ball-bearing steel with electro zinc-plated and inductively hardened tracks deliver better running properties and higher stable values.
Types of norelem roller guide systems
Roller guide systems from norelem comprises guide rails measuring up to 4080 mm in length and roller carriages in compact and heavy-duty design in 20, 30 and 45 mm. Depending on the size and dimensions, the roller guide systems can operate with static loads of up to 5,500 Newtons as well as dynamic loads up to 12,280 Newton. The combination of fixed and floating bearing rail prevents annoying tilting and unnecessary wear of the roller guide systems, the carriage can be made play-free by simply adjusting the central cam roller to the desired pre-tension in the rail. This guarantees precise running and the continuously lubricated ball bearing ensures low maintenance. An onboard scraper ensures clean running surfaces.
Roller carriages from norelem
In addition to standard steel roller carriages, norelem also offers steel roller carriages with modified polyamide wipers and die-cast aluminium roller carriages with modified polyamide wipers. The die-cast aluminium roller carriages use a patented wiper technology which ensures that both faster and quieter traversing speeds can be achieved and that the entire system can be lubricated during movement.

Positioning systems
Positioning stages and rotary stages from norelem stand for the highest precision technology. Diverse components, sensors, limit switches or cameras can be precisely positioned to within a hundredth part of a millimetre. The electrically driven, low-noise and low-maintenance motorised tables are used in machine tools, machining centres, handling systems, in fixture construction and in measuring and testing equipment. The versatile traversing and positioning modules are suitable for traversing speeds of up to 1.2 m/min and objects weighing up to 10 kg.

Exact positioning in tooling or handling systems is easily facilitated due to the virtually backlash-free guidance of the positioning stages. The positioning units are also used in fixture construction or for measuring equipment. The slide can be adjusted without having to lock or loosen the spindle, thanks to the spindle being backlash-free. The radial play of the guide is less than 0.02 mm. Another major advantage is that the spindle is also self-locking and has an additional clamping function.
