Precision Grade C7: ±0.05/300 (mm) Straightness: up to 0.2mm / 300mm
Here is an example of how to calculate the length of the Ball Screw Spindle for the desired length of travel for SFU1605 type.
Desired travel of the Ball Screw Spindle: 600mm
Manual Calculation steps for SFU 1605 Ball Screw Spindle:
600mm - Desired travel of the Ball Screw Spindle
42mm - L1 length of the SFU1605 Nut
15mm - Machined part for couplings or pulley
39mm - Position for BK,EK or FK support unit (Fixed side)
11mm - Position for BF,EF or FF support unit (Supported side)
---------------------
707mm - Total length of Ball Screw Spindle
In practice, it is recommended to add length tolerance to the travel needed for homing positions and end switches!
