Ball screws vary along three practical lines: how the balls circulate back through the nut, whether the shaft is rolled or ground, and how preload removes backlash.

Load ratings, accuracy grades and life calculations are specific to the series and size finally selected. This guide covers selection method. Final sizing should be confirmed against the rating data for the exact series you order.
Lubricant selection and service intervals are specified by the manufacturer of your guides, screws and bearings. The procedure below covers method. Where it conflicts with the documentation that shipped with your components, follow the documentation.
Controller behaviour, probing cycles and input specifications vary by control system and firmware version. Confirm the input type and probe cycle against your own controller documentation before ordering hardware.
Tariff schedules and national subheadings are updated on national timetables. The heading logic below reflects the Harmonized System nomenclature in force as of August 2026; always confirm the current subheading and duty rate with the customs authority of the importing country before you file.
