Spindle length is the overall length of a threaded spindle from one end to the other, including the threaded sections and, where applicable, the smooth shaft sections. It determines the travel distance a nut can cover on a spindle, as well as the installation length within the overall system.
Spindle length is crucial for:
- the maximum stroke or travel of the nut
- the design of linear motions and axis systems
- the stiffness and stability of the spindle
- calculating the required spindle revolutions for a specific travel distance
