Selecting a clearance/Preload for Linear Guide
Linear guide rail radial preload on the walking accuracy, load performance, rigidity, life and so have a great impact, so according to the use of the best choice of pre-pressure.
In general, consider the reciprocating motion generated by the vibration, shock, choose a negative pre-pressure (applied preload) on the service life and accuracy is good.
