Open the catalog to page 9. Motion force; otherforce arising. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Load on the individual block F: Linear guideways provides linear motion by re-circulating rolling elements between a profiled rail and a bearing block. By design, it has a self-aligning capability that can absorb most installation errors and can meet high accuracy standards. 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.
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.
Profile rails that are not attached to an installation surface may have larger tolerances in terms of straightness. General hlwin Load ratings 1. By using balls or rollers between the rail and block, a linear guideway can attain an extremely precise linear movement.
The nominal lifetime should guid be viewed as a rough estimate of the lifetime of a linear guideway. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. The mounting position depends on the requirements of the machine and the loading direction.
The O-Type back-to-back bearing configuration and lmm 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.
The WE series features equal load ratings in the radial, reverse radial and the lateral direction with contact points at 45 degrees. Open the catalog to page 8. To obtain a correct value, each para- meter must be taken into account. Open the hjwin to page 3.
The RC reinforced cap is constructed of an oil and abrasion resistant synthetic resin and elastic rubber O-ring. Table 16 Load on a block examples of calculating load on a block] Typical examples Distribution of load P-i These load factors are particularly hard to estimate when accompanied by vibration or impact load. 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.
Open the catalog to page 7. The Online Industrial Exhibition. Thus, the HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.
Giude QW series is interchangeable with the WE series. By definition, the static load rating corresponds to a static load which causes a permanent deformation of 0.
The QE series is interchangeable with the EG series. For situations where a standard block is unable to operate due to the high working temperatures, the SE option is available for use.
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. High positioning accuracy A carriage mounted with a linear guideway only has to overcome rolling friction.
The RG series is designed with a degree angle of contact. An optional stainless steel cover strip increases dust protection and promotes smooth block transition.
It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. The lifetime of a linear guideway is defined as the total travel distance covered until pitting starts General information Mounting position 1. The development of the Hiwin’s QE linear guideway is based on a four-row circular-arc contact.
This makes the friction coefficient of linear guideways very low, up to one fiftieth of that of traditional sliding guides. Long lifetime and highly precise movement With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors.
The HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. Stick-slip effects are not experienced. 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.
Open the catalog to page 6. Ultimately this results in what is known as pitting. This solution offers the high stiffness and rigidity of a guideway while obtaining high precision from the magnetic encoder. Generally, the friction coefficient is around 0. This along with the wide rail, allows the guideway to be rated for high loads, moments and rigidity.
Linear Guideways On Hiwin Corporation
Hiwin Corporation offers multiple linear guideway series, each featuring different options for sizes, loading capabilities, accuracies, and more. 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 2. The SE is a hiwn end cap option for the linear guideway that increases temperature resistance. The development of Hiwin’s QH linear guideway is based on a four-row circular-arc contact. The RG series features a roller as the rolling element instead of steel balls.
Additionally, the lower assembly height and the shorter length hidin the EG series more suitable for high-speed, automation machines and applications where space is limited. The QR series is interchangeable with the RG series.
