Linear guideways provide a type of linear motion that utilizes 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 and are able to take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. Hiwin Corporation offers multiple linear guideway series and each series features different options for sizes, loading capabilities, accuracies, and more.
Basic Dynamic Load Range: 11.38 kN - 208.36 kN
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.
Basic Dynamic Load Range: 5.35 kN - 33.35 kN
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.
Basic Dynamic Load Range: 5.23kN - 29.8 kN
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.
Basic Dynamic Load Range: 0.68 kN - 8.93 kN
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).
Basic Dynamic Load Range: 13.88kN - 108.72 kN
The development of Hiwin's QH linear guideway is based on a four-row circular-arc contact. The QH series linear guideway with SynchMotion™ Technology offers smooth movement, superior lubrication, quieter operation and longer running life. 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. The QH series is interchangeable with the HG series.
Basic Dynamic Load Range: 8.56 kN - 51.18 kN
The development of the Hiwin's QE linear guideway is based on a four-row circular-arc contact. The QE series linear guideway with SynchMotion™ Technology offers smooth movement, superior lubrication, quieter operation and longer running life. 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. The QE series is interchangeable with the EG series.
Basic Dynamic Load Range: 16 kN - 36.8 kN
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.
Basic Dynamic Load Range: 11.3 kN - 275.3 kN
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.
Basic Dynamic Load Range: 26.3 kN - 150.8 kN
Hiwin's QR series offers super high rigidity and very high load capacities. The QR series with SynchMotion™ Technology offers low friction, smooth movement, quieter operation and longer running life. In the industry where high accuracy, low noise and high rigidity is required the QR series is the ideal guideway choice. The QR series is interchangeable with the RG series.
Hiwin's positioning guideway system integrates a linear guideway with a magnetic encoder. This solution offers the high stiffness and rigidity of a guideway while obtaining high precision from the magnetic encoder. 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 E2 self-lubricating linear guideway contains a lubricator between the end cap and end seal. The block is also equipped with a replaceable/refillable oil cartridge which has a removable cap for easy replenishment of oil. The lubrication flows from the oil cartridge to the lubricator and then lubricates the grooves of the rail. The lubricator contacts the raceways of the rail and the oil from the cartridge is applied via capillary action. Hiwin's E2 option is a self-lubrication attachment that offers a maintenance free lubrication solution.
The SE is a metallic end cap option for the linear guideway that increases temperature resistance. This option enables service temperatures up to 150°C and instance temperatures up to 200°C. For situations where a standard block is unable to operate due to the high working temperatures, the SE option is available for use.
Dust Proof Options
Dust proof attachments can prevent iron chips and dust particles from entering the block and causing damage to the groove surfaces. The dust proof options are recommended to give the guideway a longer service life when exposed to a high debris environment.
The RC Reinforced Cap consists of a piece of hard plastic and a piece of an elastic O-ring. The hard plastic is made of synthetic resin which is characterized by oil resistance and abrasion resistance; the O-ring is made of rubber which is characterized by oil resistance and elasticity.
