Drive
Tables with a ball screw: These tables are equipped with precision rolled thread ballscrew drives. Screws SH and SX have a nut with internal ball recirculation. They are not preloaded, the axial clearance

is 0,1 mm maximum. These screws are the standard for precision class P10 tables. On request also for P5.

Benefits: • Robust drive. • Suitable for high axial forces. • Any drive can be fitted, e.g. manual drive, DC, AC or stepped motor. • Attachment via motor flange or indirect toothed belt drive. See table 2 for further technical information.

Screws TN and TL are fitted with an internal preloaded nut. TL screws have long leads and are therefore suitable for high travel speeds. They can be fitted in tables of precision classes P5 to P1.
