The load should therefore be multiplied by the empirical load factor. The mounting position depends on the requirements of the machine and the loading direction. The technical data in this catalog may be changed without prior notice. The QE series is interchangeable with the EG series. The EG series is a low profile, high load capacity, and high rigidity guideway block.

The cap provides high performance dust protection and is resistant to being unseated by vibration or shock. Ultimately this results in what is known as pitting. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation machines and applications where space is limited. Open the catalog to page 6.

For situations where a standard block is unable to operate due to the high working temperatures, the SE option is available for use. Therefore the QE linear guideway has broad industrial applicability in the high-tech industry hiwij high speed, low noise, and reduced dust generation is required. Elastic deformation of the linear contact surface, during loading, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.


Open the catalog to page 9. Thus, the HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion. By using balls or rollers between the rail and block, a linear guideway can attain an extremely precise linear movement. The difference between the static and dynamic rolling friction is very small so the breakaway force is only slightly greater than the motion force.

The Gude series features equal load ratings in the radial, reverse radial and the lateral direction with contact points at 45 degrees.

The good efficiency and zero play mean that the linear guideway can be used in various ways. Tuide lifetime and highly precise movement With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors. Profile rails that are not attached to an installation surface may have larger tolerances in terms of straightness. The lifetime of a linear guideway is defined as the total travel distance covered until pitting starts High positioning accuracy A carriage mounted with a linear guideway only has to overcome rolling friction.

Open the catalog to page 7. General information Properties and advantages 1. Below you will find typical mounting situations To avoid this problem and achieve a high level of rigidity and guidance accuracy, we would recommend assembling the linear guideway with reference edges and clamps on both sides.

The RG series linear guideway offers high performance for high-precision manufacturing and can achieve a longer service life than traditional ball bearing linear guideways. To obtain a correct value, each para- meter must be taken into account. By definition, the static load rating corresponds to a static load which causes a permanent deformation of 0.


The precision of the rail is defined by the straightness and evenness of the installation surfaces, since the rail is attached to these while the screws are being tightened. The nominal lifetime should therefore be viewed as a rough estimate of the lifetime of a linear guideway. The MG series is a miniature linear guideway that comes in a compact size with a Gothic arch contact design that offers high stiffness and high rigidity against moment loads in all directions.

It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. The QH series is interchangeable with the HG series. The development of Hiwin’s QH linear guideway is based on a four-row circular-arc contact. The encoder is a non-contact measuring sensor and the magnetic strip is hhiwin to prevent possible damage caused from external materials, these features ensure gukde longer service life.
