Ball retainer type LM Guide Wide track type SHW type
SHW This wide-width, high-rigidity LM Guide uses a ball cage for low noise, long-term maintenance-free, and excellent high speed.
[wide, low center of gravity]
The SHW type has a large LM rail width and a low center of gravity structure, and is most suitable for installation in places where space saving is required, and where M torque is required.
[4 direction equal load]
In order to make the four action directions (radial, revers-e radial and lateral) on the LM block have the same rated load, each steel ball row is designed to be placed at a contact angle of 45°, so no matter what position Use, wide range of uses.
[Automatic self-aligning ability]
Thanks to THK's unique circular groove front combination (DF combination) with self-aligning ability, even if preloading is applied, the mounting error can be absorbed, resulting in high-precision, smooth and stable linear motion.
The use of the ball retainer eliminates the mutual friction between the steel balls and improves the retention of the lubricating oil, thereby achieving excellent low dust generation.
Type and specialty
The flange of the LM block is threaded.
It can be installed from one of the top and bottom.
This is the type of threading performed on the LM block.
