TECHNICAL OVERVIEW

Construction and selection boundaries

Linear motion systems constrain translation while minimising friction and stick-slip. Rail flatness, preload, lubrication and contamination protection determine service life.

Common variants

Linear ball bushings Linear guide assemblies Ball screw support units

Selection notes

Define stroke, load direction, preload and required repeatability together.

TECHNICAL FAQ

Common selection questions

Does higher preload always improve accuracy?

No. Excessive preload increases friction, heat and reduces fatigue life.
