Product information
Overview
The RVD series uses a differential planetary roller screw arrangement to provide very fine linear travel per screw revolution. The supplied catalog positions the series for high-precision applications and notes differential leads down to 0.02 mm.
The model matrix below validates the data structure with selected catalog rows across 12, 15 and 18 mm nominal diameters.
Advantages
Differential lead down to 0.02 mm
Fine positioning resolution
High load capability for size
Cataloged stiffness data
Applications
Precision optical positioning
Semiconductor equipment
Metrology systems
Fine-feed mechanisms
