Features

Grants greater flexibility to machine design

The lightweight, hollow rail enables greater flexibility when it comes to machine design. Whether mounted vertically or on a wall, it can improve a machine's ability to handle highspeed operations and fast takt times.

40% Lighter than the Standard LM Rail

The LM rail is hollow, making these models much lighter than the standard LM rails.

Optimal for Applications with Moving Rails

With its lightweight nature, the LM rail can be used in mechanisms where the rail moves along a fixed LM block or as the upper shaft of a device to enable equipment to handle high-speed operations and fast takt times.

Structure and Lineup

The lineup features three sizes ranging from 15 to 25.
The Model SHS-N is available in a lineup of six block types*: C/LC, V/LV, and R/LR. *R/LR is not available for size 20.
