Sealing Systems

The HIWIN end seals firstly prevent the ingress of foreign substances such as dust particles, chips, or liquid into the block’s ball tracks and secondly reduce the amount of lubricant lost. HIWIN provides various sealing systems for the various ambient conditions of your application. The effectiveness of the end seal impacts directly on the lifetime of the linear guideway and should therefore be taken into account at the design stage and selected to suit the ambient conditions of your application

  • Wiping Action: Low
  • Displacement Resistance: Low
  • With Scraper: Yes

Specification

  • Add “+ZZ” after the specification of linear guideway
    • Example: QHW-25-CC-Z0-C+ZZ

QH Series – Heavy Load Type Linear Guideway, with SynchMotion™ Technology

The development of 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.

Features of QH Series

Low Noise Design

With SynchMotion™ technology, rolling elements are interposed between the partitions of SynchMotion™ to provide improved circulation. Due to the elimination of contact between the rolling elements, noise levels due to collision are drastically reduced.

Self-Lubricant Design

The partition is a grouping of hollow ring-like structures formed with a through-hole to facilitate circulation of the lubricant. Because of the special lubrication path design, the lubricant of the partition storage space can be refilled. Therefore, the frequency of lubricant refilling can be decreased.

The QH-series linear guideway is pre-lubricated. Performance testing at a 0.2 C (basic dynamic load) shows that after running 4,000 km no damage was apparent to either the rolling elements or the raceway.

Smooth Movement

In standard linear guideways, rolling elements on the load side of the guide black begin rolling and push their way through the raceway. When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QH linear guideway, with SynchMotion™ technology prevents this condition. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to prevent contact with one another thus keeping the element’s kinetic energy extremely stable in order to effectively reduce fluctuations in rolling resistance.

High Speed Performance

The QH series offers excellent high-speed performance due to the partitions of the SynchMotion™ structure. They are employed to separate the adjacent balls thereby resulting in low rolling traction and the metallic friction between adjacent balls is eliminated.

QH Series Application Examples

  • Automation Devices
  • High-Speed Transportation Equipment
  • Precision Measuring Equipment
  • Semiconductor Manufacturing Equipment

WE Type – Four-Row Wide Rail Linear Guideway

Construction

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 self-aligning capacity 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.

WE Series Application Examples

  • Automation Devices
  • High-Speed Transportation Equipment
  • Precision Measuring Equipment
  • Semiconductor Manufacturing Equipment
  • Precision Machining Machines
  • Blow Molding Machines
  • Single Axis Robot-Robotics
  • Single Axis Equipment with High Anti-Rolling Requirement
