Techdrives has published linear motion FAQs on its website to help machine builders who specify products such as linear actuators, screw jacks and ball screws. These FAQs are useful both for less experienced designers and those who want to check that their existing knowledge is up to date.
What follows is typical of the FAQs, but use the links to see more and to read the answers provided by Techdrives.
Industrial electric linear actuators
- Acme thread or ball screw designs? What duty cycles are allowed?
- What speed accuracy do linear actuators achieve?
- Are there limits for side loads and buckling?
- What lifetime can I expect?
- What are critical speeds?
- Can I position with linear actuators?
