How to adjust drylin® T linear rail clearance
Why is adjustment important?
There are numerous reasons why linear systems might need adjustment and ensuring that the adjustment is done correctly is important.
Proper adjustment helps:
- reduce play
- reduce vibration
- Clearance adjustment
- improve positioning accuracy
- prevent binding and stick-slip
- running surface optimised
- increase service life
What are the main reasons for adjustments?
Carriages binding
Stick-slip
Excessive preload
Increase or decrease friction

Frequently asked questions
Overtightening is one of the most common causes of failures when it comes to linear carriage adjustment. Removing all "play" in a carriage means potentially excessive friction, sticking or binding; preventing smooth operation and premature failure.
One can help the other. A pre-loaded carriage helps internalise the tension by removing any clearance, it effectively helps reduce the backlash. A carriage with that is suffering from backlash means there is play or clearance when not needed.
There are many reasons for this but the key ones are:
- over tightening
- issues with the parallelism of rails ( when more than one rail is in use)
- if the carriages require lubrication, then a lack of lubrication can cause this
- if the carriage or rail is damaged.
Not all carriages can be adjusted. Some don't need to be. We have a wide range of both options
