Ball Screws feature elastic spacer technology.
Ball Screws and Nuts

Ball Screws feature elastic spacer technology.

Ball Screws use elastic spacers to separate recirculating balls inside nut, allowing them to achieve extremely fine and slow motion consistently. When nut is fully assembled, slight compression of each elastic spacer between 2 adjacent balls ensures sustained close guidance during recirculation inside nut. Hole in middle of spacer allows adjacent balls to touch in event of jamming, preventing...
