HIWIN Corporation- Global Worldwide

The QW series is interchangeable with the WE series. To obtain a correct value, each para- meter must be taken into account. By using balls or rollers between the rail and block, a linear guideway can attain an extremely precise linear movement. The O-Type back-to-back bearing configuration and an integrated recirculation unit optimize bearing circulation greatly improving moment load capacities lj promoting smooth motion.

The nominal lifetime should therefore be viewed as a rough estimate of the lifetime of a linear guideway. An optional stainless steel cover strip increases dust protection and promotes smooth block transition. 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.

The QR series is interchangeable with the RG series.

Hiwin Corporation offers multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more. The Buide is a metallic end cap option for the linear guideway that increases temperature resistance. 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.

The RG series features a roller as the rolling element instead of steel balls. Open the catalog to page 2. 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.


A linear guideway permits linear movement with the aid of rolling elements. The Online Industrial Exhibition.

Linear guideways provides linear motion by re-circulating rolling elements between a profiled rail and a bearing block. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation machines and applications where yuide is limited. Table 16 Load on a block examples of calculating load on a block] Typical examples Distribution of load P-i General information Mounting position 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. Complete or partial reproduction is not permitted without our permission. 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.

Linear Guideways

The RG series is designed with a degree angle of contact. The lifetime of a linear guideway is defined as the total travel distance covered until pitting starts The load should therefore be multiplied by the empirical load factor. Below you will find typical mounting situations The mounting position depends on the requirements of the machine and the loading direction. This along with the wide rail, allows the guideway to be rated for high loads, moments and rigidity.

The QE series is interchangeable with the EG series. The good efficiency and zero play mean that the linear guideway can be used in various ways.

With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Stick-slip effects are not experienced. The development of Hiwin’s QH linear guideway is based on a four-row circular-arc contact. This makes the friction coefficient of linear hiain very low, up to one fiftieth of that of traditional sliding guides. Open the catalog to page 6. Once this permanent deformation exceeds a particular level, it impacts on how easily the guide moves.


Therefore the QH linear guideway has broad industrial applicability in the high-tech industry where high speed, low noise, and reduced dust generation is required. Profile rails that are not attached to an installation surface may have larger tolerances in terms of straightness. Open the catalog to page These load factors are particularly hard to estimate when accompanied by vibration or impact load.

It features equal load ratings in the radial, reverse radial hiqin lateral directions, and self-aligning to absorb installation-error. General information Properties and advantages 1. Generally, the friction coefficient is around 0. This solution offers the high stiffness and rigidity of a guidw while obtaining high precision from the magnetic encoder.

Ultimately this results in what is known as pitting. Long lifetime and highly precise movement With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors.

By design, it has a self-aligning capability that can absorb most installation errors and can meet high accuracy guidw. 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.

It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. The HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization.

The values are stated in the tables for each linear guideway Hiwin’s positioning guideway system integrates a linear guideway lmm a magnetic encoder.
