THK Caged Ball LM Guide SRS Block

Caged Ball LM Guide model SRS has a structure where two raceways are incorporated into the compact body, enabling the model to receive loads in all directions, and to be used in locations where a moment is applied with a single rail. In addition, use of ball cages eliminates friction be tween balls, thus achieving high speed, low noise, acceptable running sound, long service life, and long-term maintenance-free operation.


[Low Dust Generation]
Use of ball cages eliminates friction between balls and retains lubricant, thus achieving low dust generation. In addition, the LM block and LM rail use stainless steel, which is highly resistant to corrosion.


[Compact]
Since SRS has a compact structure where the rail cross section is designed to be low and that con tains only two rows of balls, it can be installed in space-saving locations.


[Lightweight]
Since part of the LM block (e.g., around the ball relief hole) is made of resin and formed through in sert molding, SRS is a lightweight, low inertia type of LM Guide.
