Applications with very short strokes and longer duty cycles require special consideration.

Usually when looking at the p * v value the heat dissipation via the spindle is also taken into account. If the stroke is very short, the frictional heat is only generated on part of the spindle and it is more difficult to dissipate heat.

Frequently, very dynamic and highly stressed applications with short strokes also wear the spindle. Here it is advisable to look at the bearing pair much more intensively. Plastic threaded nuts or the use of hardened threaded spindles or at least high-alloy materials are recommended.

junaspin will be happy to support you in the selection and design of your screw drive. We would be happy to discuss your application with you. In addition to the technical requirements, economic aspects are of course also relevant here. We can incorporate relevant experience from “real applications” here.
