In the era of automation and Industry 4.0, linear guideways have become a crucial component in many manufacturing processes. Hiwin Corporation offers a wide range of linear guideway series, each featuring different options for sizes, loading capacity, accuracy, and more. In this article, we will explore the various types of linear guideways offered by Hiwin Corporation and their unique features.
Linear Guideway Technology
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. This feature enables linear guideways to achieve high precision and greatly enhanced moving accuracy while carrying loads in all directions.
HG Series
The HG series linear guideways are designed with load capacity and rigidity higher than other similar products. It features equal load ratings in the radial, reverse radial, and lateral directions and self-aligning capability to absorb installation-error. The HG series linear guideway can achieve a long life with high speed, high accuracy, and smooth linear motion.
EG Series
The EG series is a low profile, high load capacity, and high rigidity guideway block. It features equal load ratings in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. The lower assembly height and shorter length of the EG series make it ideal for space-saving applications.
WE Series
The WE series linear guideway with SynchMotion technology possesses 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.
QR Series
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 industries where high accuracy, low noise, and high rigidity are required, the QR series is the ideal guideway choice.
PG 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 by external materials, ensuring a longer service life.
E2 Series
The E2 self-lubricating linear guideway has a lubricator installed between the end cap and end seal. The block is also equipped with a replaceable/refillable oil cartridge with a removable cap for easy replenishment of oil. Lubrication flows from the oil cartridge to the lubricator and coats the grooves of the rail and raceway via capillary action.
SE Series
The SE series metal end cap option increases temperature resistance, enabling service temperatures up to 150°C and instance temperatures up to 200°C. This option is available for use in situations where a standard block is unable to operate due to high working temperatures.
Dust Proof Options
Dust proof attachments prevent material debris and dust particles from entering the block and causing damage to grooved surfaces. Dustproof options are recommended when a guideway is exposed to a high debris environment to ensure extended service life.
Reinforced Caps
The RC reinforced cap is constructed of an oil and abrasion-resistant synthetic resin and elastic rubber O-ring. The cap provides high-performance dust protection and is resistant to being unseated by vibration or shock., Hiwin Corporation offers a wide range of linear guideway series that cater to different industries and applications. By understanding the unique features and benefits of each series, manufacturers can select the most suitable linear guideway for their specific needs, ensuring high accuracy, load capacity, and service life in their manufacturing processes.
