High-Speed Ball Screws have elastic spacers.
Mechanical Components and Assemblies

High-Speed Ball Screws have elastic spacers.

With design that avoids inter-ball friction and torque build-up at slow speeds, UltraSpeed KES ball nut incorporates spacers between balls and plastic tubes in recirculating channels. It also features dual ball return systems with deflectors that guide balls in tangential direction, away from shaft and into return channels integrated inside nut body. With dn rating of 160,000, product is capable...

Ball Screws feature elastic spacer technology.
Mechanical Components and Assemblies

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...
