Screw drives are designed to absorb or transmit axial forces. If radial forces occur in the application, they should be absorbed by linear guides.
In practice, of course, it happens again and again that threaded nuts also receive radial forces. This can lead to noises in individual cases, especially with sliding screw drives.
junaspin is happy to support you in the selection and design of your screw drive. In the case of very small radial forces or very rare movements, it is possible to do without an external guide. In addition to the pure calculation, experience from “real applications” and tests can also be incorporated.
