Open the catalog to page It features equal hwiin ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. 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 hiwun are caused by the projection of the load.
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. Open the catalog to page 2. The RG series linear guideway offers high performance for high-precision manufacturing and can achieve a longer service l, than traditional ball bearing linear guideways. Open the catalog to page 9.

Motion force; ugide arising. The nominal lifetime should therefore be viewed as a rough estimate of the lifetime of a linear guideway. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Hiwin’s positioning guideway system integrates a linear guideway with a magnetic encoder.
The Online Industrial Exhibition. Generally, the friction coefficient is around 0. An optional stainless steel cover strip increases dust protection and promotes smooth block transition.
Compared with a standard sliding guide, the friction coefficient here is just one fiftieth.
General information Mounting position 1. The development of the Ln QE linear guideway is based on a four-row circular-arc contact. General information Load ratings 1.
General information Operating Load 1. The difference between the static and dynamic rolling friction is very small so the breakaway force is only slightly greater than the motion force. Long lifetime and highly precise movement With a sliding guide, the different thicknesses hiqin lubrication film may result in accuracy errors.
By definition, the static load rating corresponds to a static load which causes a permanent deformation of 0. By using balls or rollers between the guidee and block, a linear guideway can attain an extremely precise linear movement. Therefore the QE linear guideway has broad industrial applicability in the high-tech industry where high speed, low noise, and reduced dust generation is required.
It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies.

This along with the wide rail, guidde the guideway to be rated for high loads, moments and rigidity. The RG gkide features a roller as the rolling element instead of steel balls. High positioning accuracy A carriage mounted with a linear guideway only has to overcome rolling friction. Load on the individual block F: For situations where a standard block is unable to operate due to the high working temperatures, the SE option is available for use. The HG series guidw guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization.
The development of Hiwin’s QH linear guideway is based on a four-row circular-arc contact. The O-Type back-to-back bearing configuration and an integrated recirculation unit optimize bearing circulation greatly improving moment load capacities and promoting smooth motion. 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.
Linear guideways provides linear motion by re-circulating rolling elements between a profiled rail and a bearing block. The cap provides high performance dust protection and is resistant to being unseated by vibration or shock.
The good efficiency and zero play mean that the linear guideway can be used in various ways. Open the catalog to page 6.
This makes the friction coefficient of 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. This solution offers the high stiffness and rigidity of a guideway while obtaining high precision from the magnetic encoder. The values are stated in the tables for each linear guideway Stick-slip effects are not experienced.
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. Table 16 Load on a block examples of calculating load on a block] Typical examples Distribution of load P-i The QW series is interchangeable with the WE series.
Below you will find typical mounting situations The SE is a metallic end cap option for the linear guideway that increases temperature resistance. The lifetime of a linear guideway is defined as the total travel distance covered until pitting starts By design, it has a self-aligning capability that can absorb most installation errors and can meet high accuracy standards.
These load factors are particularly hard to estimate when accompanied by vibration or impact load. Once this permanent deformation exceeds a particular level, it impacts on how easily the guide moves.
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 EG series is a low profile, high load capacity, and high rigidity guideway block.
The QR series is interchangeable with the RG series. Profile rails that are not attached to an installation surface may have larger tolerances in terms of straightness.
