Description

Hiwin linear guideways are mechanical systems that provide smooth, precise, and controlled linear motion in various machinery and applications. They are a popular choice due to their high precision, durability, and versatility.
Key features
Linear motion: They enable straight-line movement using rolling elements like balls or rollers between a rail and a bearing block.
Reduced friction: The coefficient of friction is significantly lower than traditional sliding guides, resulting in smoother motion and less wear.
High precision and accuracy: Hiwin guideways are known for their ability to deliver micron-level precision and repeatable movement, crucial for applications demanding tight tolerances.
Load-bearing capacity: They are designed to handle significant loads in all directions (radial, reverse radial, and lateral) due to features like optimized groove designs and contact angles.
Rigidity and stiffness: Hiwin guideways are built to be rigid and resistant to deflection, especially under heavy loads.
Long service life: Made from high-grade steel and advanced hardening techniques, they offer resistance to wear and corrosion, ensuring a longer operational lifespan.
Easy installation and maintenance: They come with features like pre-drilled holes and standardized dimensions for easier installation, and many series offer options for self-lubrication to reduce maintenance needs.
Types of Hiwin linear guideways
Hiwin offers various linear guideway series, each designed for specific applications and needs. These include:
HG series: Heavy load, ball-type, high rigidity, often used in CNC machines.
EG series: Low profile with high load capacity, suitable for automation machines with limited space.
RG series: Roller type, providing maximum stiffness for heavy-duty applications like milling and grinding.
MG series: Miniature and compact, designed for medical devices and small automation systems.
QH and QE series: Feature SynchMotion™ Technology for smoother and quieter operation.
WE series: Wide rail design for high load capacity and rigidity.
PG series: Integrates a magnetic encoder for high precision positioning.
Applications
Hiwin linear guideways are used in many industries for various applications, such as:
CNC machining and 3D printing
Robotics and automation
Semiconductor and medical equipment manufacturing
Packaging, aerospace, textile, and printing industries
Food and beverage processing
Choosing the right Hiwin linear guideway
Selecting the correct Hiwin linear guideway involves evaluating several key factors:
Load capacity: Consider both static and dynamic loads.
Accuracy class: Hiwin offers multiple accuracy levels to match application precision needs.
Space limitations: Account for available mounting space.
Operating environment: Consider factors like temperature and contaminants, which may require specific materials or coatings.
Travel length and speed: Ensure components can handle the required motion.
Mounting space and orientation: Select components that fit the system’s design.
