Precision ballscrews
Ballscrews with elastic spacers separating recirculating balls consistently achieve slow, fine motion down to 1 µm/sec.
FEATURES & BENEFITS
- Elastic spacers under slight compression eliminate inter-ball friction and associated problems such as servo loop instability and intermittent idling torque spikes
- Special spacer shape — two back-to-back Belleville springs with a hole in the middle — ensures sustained close guidance during recirculation, while preventing cracking during overload by allowing adjacent balls to touch
- Spacers do not limit the number of load balls compared to spacer-less ball nuts, and by storing lubricant, they can extend ballscrew life
