- Heave Load Type Linear Guideways -

H Series

Applicable industries of H series:
Grinding,Milling, and Drilling machine,Lathe,Electric discharge machine, Wire cutting machine, Wood cutting machine,Precision measure equipment, Machine center

(1)Self-aligning capability
By design, the circular-arc groove has contact points at 45 degrees. H 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 H 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 H 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.
