LINEAR GUIDEWAYS Linear guideways & accessories A linear guideway makes it possible to move in a linear motion with rolling elements. The use of balls and rollers between the rail and block in a linear guideway makes precise linear movements possible. Compared with a standard sliding guide, the friction coefficient here is just one fiftieth. The high efficiency and zero backlash mean that the linear guideway can be used in various ways.

Roller guides Roller guides are mainly used in heavy-duty solutions, such as in machine tools, presses, injection moulding machines or measuring machines. They are characterised by their very high load capacity and very high rigidity. Select the right series for your requirements here. Alternatively, you can configure your suitable linear guide with the appropriate accessories directly in our product configurator. CAD data and technical drawings are also available for download here. Linear guideway of RG and QR series Page 96 - Roller guides for heavy-duty applications - With maximum requirements...

Linear guideways Product overview Integrated distance measuring system Linear guideways with an integrated magnetic distance measuring system are optimised for measuring linear movements. Compactly integrated, the encoder is attached to the block and the measuring tape is inserted into the profile rail protected by the cover strip. With electrical shielding and real-time signal output, our linear guides with MAGIC distance measuring system are used in automation, handling or in axes with direct distance measurement, such as linear motor axes.

Linear guideways General information 2. General information 2.1 Properties and advantages 1. High positioning accuracy A carriage supported by a linear guideway only has to overcome rolling friction. The difference between static and dynamic rolling friction is very small, which means that the breakaway force is only slightly higher than the moving force. No stick-slip effects occur. 2. Long service life with particularly precise movement With a sliding guide, errors in accuracy can occur due to different lubricant film thicknesses. Due to the sliding friction and frequent lack of lubrication,...

If a linear guideway system is subjected to excessive loads or impacts during movement or at a standstill, localised permanent deformation occurs between the track and balls. As soon as this permanent deformation exceeds a certain level, it affects smooth operation of the guideway. According to its basic definition, the static load rating corresponds to a static load that causes permanent deformation of 0.0001 x ball diameter at the contact point that is loaded the most. The values are given in the tables for each linear guideway system. Using these tables, the designer can select a suitable...

2.4 Service life calculation 2.4.1 Definition of service life The constant and repeated loading of tracks and bafts of a linear guideway causes fatigue on the track surface. In the end, so-called pitting formation occurs. The service life of a linear guideway is defined as the total travel distance covered until pitting occurs on the surface of the track or balls. The service life can be very different even if linear guideways are manufactured in the same way and used under the same movement conditions. Therefore, the nominal service life is taken as a reference value for estimating the service...

To take into account external influences on the service fife of the profile rails which are not directly included in the calculation (e.g. vibrations, jolting and high speed), the dynamic equivalent load is multiplied by the load factor according to Table 2.2. For short-stroke applications (stroke < 2 x block lengths), the calculated load factor must be doubled. L Nominal service life [km] Cdyn Dynamic load rating [N] P Dynamic equivalent load [N] The service life in hours is calculated from the nominal service life with the aid of the travel speed and movement frequency. L Nominal service life...
