In every linear guideway the cage can be shifted from the centre along the longitudinal axis. Cage creep reduces the optimal load distribution and requires a correct stroke to return the cage to a centered position. the correction stroke requires a large expense of energy.
The causes of cage creep
- High accelerations and speeds
- Vertical installation of the guideway
- Uneven load distribution
- Protruding cage
- Different heat expansion coefficients
- Design and installation (lacking rigidity and/or accuracy of the connecting structure)
The benefits and advantages of FORMULA-S

- No force required for cage reset
- Accelerations up to 300 m/s2 (30 g)
- Max speed 1 m/s
- Easy to install and/or uninstall
- Extended service life Vacuum-compatible up to 10-7 mbar
