Linear guideways provide linear motion by re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy while carrying loads in all directions. Hiwin Corporation offers a variety of linear guideway series, each featuring different options for sizes, loading capacity, accuracy, and more.
The HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, the HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.
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. 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.
The CG series linear guideways have moment load capacities up to 50% higher than standard HG Assemblies. 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. An optional stainless steel cover strip increases dust protection and promotes smooth block transition.
The RG series features a roller as the rolling element instead of steel balls. The RG series is designed with a 45-degree angle of contact. 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 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 WE series features equal load ratings in the radial, reverse radial and the lateral direction with contact points at 45 degrees. This along with the wide rail, allows the guideway to be rated for high loads, moments and rigidity. By design, it has a self-aligning capability that can absorb most installation errors and can meet high accuracy standards. The ability to use a single rail and to have the low profile with a low center of gravity is ideal where space is limited and/or high moments are required.
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 MG series also offers anti-corrosion protection which all material is in a special grade of stainless steel for compatibility in various working environments. The MG series is available in a narrow block type (MGN) and also with an enlarged width (MGW).
The development of Hiwin’s QH linear guideway is founded on a four-row circular-arc contact design. With the integration of SynchMotion™ Technology, the QH series ensures smooth movement, improved lubrication, quieter operation, and a longer running life. This makes the QH linear guideway ideal for high-tech industries where high speed, low noise, and reduced dust generation are critical. Furthermore, the QH series is fully interchangeable with the HG series, providing flexibility across various industrial applications.
The development of Hiwin’s QE linear guideway is based on a four-row circular-arc contact design. Equipped with SynchMotion™ Technology, the QE series provides smooth movement, enhanced lubrication, quieter operation, and extended running life. This makes the QE linear guideway highly applicable across industries, particularly in high-tech environments where high speed, low noise, and minimized dust generation are essential. Additionally, the QE series is fully interchangeable with the EG series, offering flexibility for various applications.
The QW series linear guideway with SynchMotion™ Technology possesses all the advantages of the WE series, which features high moment rigidity and is suitable for single rail or space saving applications. With the SynchMotion™ technology it also provides quieter and smoother movement, superior lubrication, and longer service life. The QW series is interchangeable with the WE series.
Hiwin’s QR series provides exceptionally high rigidity and impressive load capacities. With SynchMotion™ Technology, the QR series ensures low friction, smooth movement, quieter operation, and an extended running life. In industries demanding high accuracy, low noise, and high rigidity, the QR series is the perfect guideway solution. Additionally, the QR series is fully interchangeable with the RG series for added versatility.
Hiwin’s positioning guideway system integrates a linear guideway with a magnetic encoder, offering high stiffness and rigidity along with precise measurements. The non-contact measuring sensor ensures high precision, while the magnetic strip is embedded to protect against damage from external materials, resulting in a longer service life. This solution is ideal for applications requiring both durability and accuracy.
