7.2.5 Preload Classes
Preload class is defined as a proportion of the dynamic load capacity C (see Chapter 17). The amount of preload is usually based on the intended use of the guide rail.
Increasing preload…
- … increases rigidity
- … increases displacement resistance
- … reduces service life
| Preload Class | Preload | Corresponding Accuracy Class |
|---|---|---|
| V0 | Slight clearance, max. 0.01 • C | G3 |
| V1 | 0 to 0.03 • C | G1 or G3 |
