One would need to know the advance ratios ( one turn =?) in order to choose the right one.
Each screw has a descriptive name, e.g. SFU1204: The first three letters identify the type of nut-screw and its bushing to match, the first two digits the diameter the last two the pitch, and then from these then the relative advance for each model is derived. Here is a summary table:
| 12mm diameter | 16mm diameter |
| 1204--> 4mm pitch | 1604--> 4mm pitch |
| 1205--> 5mm pitch | 1605--> 5mm pitch |
| 1610--> 10mm pitch | |
| Diameter 20mm | 25mm diameter |
| 2004--> 4mm pitch | 2504--> 4mm pitch |
| 2005--> 5mm pitch | 2505--> 5mm pitch |
| 2510--> pitch 10mm |
Since these leadscrews are single-principle, the pitch corresponds to the feed. So to know the linear feed at each turn of the screw you have to refer to the pitch itself of each individual model. For example with a 4mm pitch--> 4mm linear feed.
