THK SRS Caged Ball® Miniature LM Guides

SRS Structure & Features

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 contains 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 insert moulding, SRS is a lightweight, low inertia type of LM Guide.
