 Features of HL Series 

(1) Self-aligning capability 

By design, the circular-arc groove has contact points at 45 degrees. HL 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 HLseries 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 HL 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.
