linear rail ball bearings lm block PHGH55CA precision slide assembly rails

Short Description:

Linear guides, also known as linear guideway, sliding guides and linear slides, including guide rail and sliding block, it is used to support and guide the moving parts to make reciprocating linear motion in a given direction. Mainly used in high-precision or high-speed linear reciprocating motion applications, can bear a certain torque, and can achieve high-precision linear motion under high load

    product description

    PHG  series  linear motion guide rail are  designed  with  load  capacity  and  rigidity  higher  than  other  similar  products  with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. Thus, PYG®  HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.


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