1.Structure and Features of THK HSR30:
The steel ball are rolled along the LM rail and the LM block by precision grinding of the four rows of
rolling surfaces; the ball is held by the ball retainer and the ball returner assembled on the LM block.
Listed as a circular motion. In order to have the same rated load in the four directions of action (radial,
reverse radial and lateral) on the LM block, each steel ball row is designed to be placed at a contact angle
of 45, so that it can be used regardless of posture . And because it can apply equal preload, it can maintain
the low friction coefficient while strengthening the rigidity in four directions. At the same time, because of
the low section height and high rigidity design of the LM block, stable stability can be obtained. High
precision linear motion. [4-direction equal load] In order to make the four action directions (radial, reverse
radial and lateral) on the LM block have the same rated load, each steel ball row is designed to be
arranged at the contact angle 45, so It can be used in any position and has a wide range of uses.
2.Automatic self-aligning ability of THK HSR30:
Thanks to THK's unique circular groove front combination (DF combination) with automatic adjustment
capability, even if preloading is applied, the mounting error can be absorbed, resulting in high-precision,
smooth and stable linear motion.
3.World Standard Size of THK HSR30:
The size design of the SHS is based on the HSR model of the all-steel ball LM Guide developed by THK,
the pioneer of the linear motion system. [low center of gravity.
4.High rigidity of THK HSR30:
By miniaturizing the cross-sectional dimensions of the LM rail, the center of gravity is lowered and high
rigidity is achieved.
5.We have a large number of off-the-shelf models, including:
6.THK HSR30M1A high temperature resistant slider can run freely within 150 degrees of standard load and has strong anti-corrosion characteristics. Most suitable for linear guiding systems, excellent high-speed running performance, long service life and long-term maintenance-free.
