STEP 5. How to Calculate the Length
1. Total Screw Length.
2. Center Distance Between Mounting Seats.
3. Effective Thread Length.
4. Nut Free Stroke = Effective Thread Length - Nut Length
2. Center Distance Between Mounting Seats.
3. Effective Thread Length.
4. Nut Free Stroke = Effective Thread Length - Nut Length
* Thread Length = Total Screw Rod Length - Processing Lengths of Both Ends
* Absolute Stroke = Thread Length - Nut Length - Mounting Seat Shrinkage - Flange Fixing Screw Space
* Absolute Stroke = Thread Length - Nut Length - Mounting Seat Shrinkage - Flange Fixing Screw Space
