(1) Self-aligning capability By design, the circular-arc groove has contact points at 45 degrees. HG series linear guide can absorb most installation errors due to surfaceirregularities 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.

(2) Interchangeability
Because of precision dimensional control, the dimensional tolerance of HG series linear guide  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.

(3) High rigidity in all four directions
Because  of  the  four-row  design,  the  HG  series  linear  guide  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
