⑤Features of HG series
(1) Self-aligning capability
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.
(2) Interchangeability
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.
(3) High rigidity in all four directions
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.
