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.
Cross-Sectional Comparison between the
Standard LM Rails and Lightweight LM Rails
Comparison of the Weights of the Standard and Lightweight LM Rails
Unit: kg/m
| Model No. | LM rail type | LM rail weight | Weight comparison |
| SHS15-N | Hollow | 0.75 | 40% lighter |
|---|---|---|---|
| SHS15 | Standard | 1.3 | |
| SHS20-N | Hollow | 1.32 | 40% lighter |
| SHS20 | Standard | 2.3 | |
| SHS25-N | Hollow | 1.90 | 40% lighter |
| SHS25 | Standard | 3.2 |
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.
