Load Calculations for Velmex Stages
- Loads
- BiSlide
- UniSlide
- XSlide
- Rotary Tables
Load Capacities and the calculations for each are outlined on the tabs for each brand.
Load Capacity is the maximum recommended payload for a stage or slide to operate efficiently. (Measured with load centered - except cantilever - on a single axis stage.) Sometimes also referred to as "Permissible".
For the various definitions of load when the stage is in motion and in different positions, please refer to our Load Parameters page.

| 1Note: Because of the interlocking nature of the BiSlide carriage and the dovetail ways, the maximum recommended load centered (normal) or under thrust would be comparable whether the slide was upright (Normal – LN), Inverted (LI) or set on the Edge (LE). |
