Hello, I would like to know what precision these screws have.
The precision grade of the ball screws found in this category is C5.

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.
