HIWIN HGH55HA Linear Guideway Linear Bearing Rail Linear Guide Carriage
Designed to meet the exacting standards of precision measuring equipment, the HIWIN HGH55HA Linear Guideway delivers unmatched stability and accuracy for critical dimensional inspection applications. This premium linear bearing system incorporates HIWIN's decades of motion control expertise to provide the foundation for high-performance coordinate measuring machines (CMM), optical measurement systems, and laboratory-grade metrology instruments.
The HGH55HA features HIWIN's specialized ultra-precision bearing technology, ensuring vibration-free movement essential for micron-level measurement repeatability. Its thermally optimized construction minimizes positional drift during sensitive scanning operations, while the precision-ground surfaces maintain exceptional straightness for reliable probe positioning. The guideway's advanced damping characteristics effectively neutralize environmental vibrations that could compromise measurement integrity.
Engineered for cleanroom-compatible inspection systems, this HIWIN solution incorporates contamination-resistant seals to protect sensitive components in particle-controlled environments. The smooth, consistent motion profile enables precise positioning required for modern non-contact measurement technologies and high-resolution surface analysis.Trusted by leading metrology equipment manufacturers worldwide, the HGH55HA exemplifies HIWIN's commitment to precision in measurement applications. From aerospace component verification to automotive quality control, this linear guideway provides the rock-solid stability that advanced dimensional measurement demands.
By design, the circular-arc groove has contact points at 45 degrees. HG series can absorb most installation errors due to surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements and the shift of contact points. Self-aligning capability, high accuracy and smooth operation can be obtained with an easy
installation.

Because of precision dimensional control, the dimensional tolerance of HG series can be kept in a reasonable range, which means that any blocks and any rails in a specific series can be used together while maintaining dimensional tolerance. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.
Because of the four-row design, the HG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. Furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway allowing large permissible loads and high rigidity.
