Once this permanent deformation exceeds a particular level, it impacts on how easily the guide moves. 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.
Generally, the friction coefficient is around 0. Below you will find typical mounting situations These load factors are particularly guie to estimate when accompanied by vibration or impact load.
This along with the wide rail, allows the hhiwin to be rated for high loads, moments and rigidity. The values are stated in the tables for each linear guideway The HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization.
General information Mounting position 1. The load should therefore be multiplied by the empirical load factor. Hiwin’s positioning guideway system integrates a linear guideway with a magnetic encoder. For situations where a standard block is unable to operate due to the high working temperatures, the SE option is available for use.
The RG series features a roller as the rolling element instead of steel balls. The QE series is interchangeable with the EG series. General information Lifetime calculation Load factor fw The loads affecting a linear guideway include the weight of the block, the inertia at the start and end of movements and load torques which are caused by the projection of the load.
The encoder is a non-contact measuring sensor and the magnetic strip is embedded to prevent possible damage caused from external materials, these features ensure a longer service life.

Open the catalog to page 9. Long lifetime and highly precise movement With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors.
The QH series is interchangeable with the HG series. The precision of the rail is defined by the straightness and evenness of hiin installation surfaces, since the rail is attached to these while the screws are being tightened. Compared with a standard sliding guide, the friction coefficient here is just one fiftieth.
Elastic deformation of the linear contact surface, during loading, is greatly reduced thereby offering greater rigidity and higher load guude in all 4 load directions. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation hiein and applications where space is limited. Table 16 Load on a block examples of calculating load on a block] Typical examples Distribution of load P-i By definition, the static load rating corresponds to a static load which causes a permanent deformation of 0.
By design, it has a self-aligning capability that can absorb most installation errors and can meet high accuracy standards.

Ultimately this results in what is known as pitting. The development of the Hiwin’s QE linear guideway is based on a four-row circular-arc contact. This makes the friction coefficient ln linear guideways very low, up to one fiftieth of that of traditional sliding guides.
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 WE series features equal load ratings in the radial, reverse radial and the lateral direction with contact points at 45 degrees.
