1. Define the envelope: available shaft diameter and nut outer diameter usually set the series.
2. Calculate loads: radial load and torque at the nut, including acceleration forces. At 10G, inertia dominates in pick-and-place heads.
3. Check speed and stroke: confirm the permissible speed and that the stroke leaves enough ball engagement.
4. Choose preload: clearance for smooth low-force motion, series-specific standard or T1 light preload when angular backlash matters.
5. Verify life: estimate rated life in km of travel. The 2024 catalog reports internally verified tests on selected UVT sizes at 860 mm/s, 10G and 15 mm stroke. These do not establish a whole-series life guarantee; request raw test conditions and calculate application life.
