💡 How do you keep tolerance tight when installing heavy duty linear slides?
Tweaking the preload requires understanding how the rollers seat against the hardened shafts.
- Set the eccentric collars so the carriage glides freely without side play
- Secure the base plates with level shims to prevent uneven wear
- Cycle the unit by hand to verify smooth travel before final bolting
