With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy.

The QH series is interchangeable with the HG series. General information Properties and advantages 1. Thus, the HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.

These load factors are particularly hard to estimate when accompanied by vibration or impact load. General information Load ratings 1. 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. Generally, the friction coefficient is around 0. The WE series features equal load ratings in the radial, reverse radial and the lateral direction with contact points at 45 degrees.

The RG series features a roller as the rolling element instead of steel balls. The QR series is interchangeable with the RG series.

The RC reinforced cap is constructed of an oil and abrasion resistant synthetic resin and elastic rubber O-ring. Below you will find typical mounting situations The technical data in this catalog may be l, without prior notice. The SE is a metallic end cap option for the linear guideway that increases temperature resistance.

The MG series also offers anti-corrosion protection which all material is in a special grade of stainless steel for compatibility in various working environments.


To avoid this problem and achieve a high level of rigidity and uiwin accuracy, we would recommend assembling the linear guideway with reference edges and clamps on lk sides.

General information Operating Load 1. Open the catalog to page 8. The QW series is interchangeable with the WE series. The mounting position depends on the requirements of the machine and the loading direction. 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.

By definition, the static load rating corresponds to a static load which causes a permanent deformation of 0. The Gujde series is interchangeable with the EG series. By using balls or rollers between the rail and block, a linear guideway can attain hiwon extremely precise linear movement. 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.

The EG series is a low profile, high load capacity, and high rigidity guideway block.

The nominal lifetime should therefore be viewed as a rough estimate of the lifetime of a linear guideway. General information Lifetime calculation Load factor fw The loads affecting a linear guideway include the weight of the block, the inertia at the hiwinn and end of movements and load torques which fuide caused by the projection of the load.

Long lifetime and highly precise movement With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors.

It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Compared with a standard sliding guide, the friction coefficient here is just one fiftieth. An optional stainless steel cover strip increases dust protection and promotes smooth block transition. Open the catalog to page 3. 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.


Hiwin Corporation offers multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more. To obtain a correct value, each para- meter must be taken into account. The load should therefore be multiplied by the empirical load factor.

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.

Stick-slip effects are not experienced. Open the catalog to page 2.

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 ugide. General information Mounting position 1.

Profile rails that are not attached to an installation surface may have larger tolerances in terms ugide straightness. Motion force; otherforce arising. Open the catalog to page 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 Online Industrial Exhibition.

Complete or partial reproduction is not permitted without our permission. 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. This along with the wide rail, allows the guideway to be rated for high loads, moments and rigidity. Open the catalog to page 6.
