Description
THK 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 gen-eration. In addition, the LM block and LM rail use stainless steel, which is highly resistant to cor-rosion.
[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.
