Notes on dimensional table

Note1) Cut shafts (K) are build-to-order. In the specification table, "standard shaft length" and "maximum shaft length" are values for rolled shafts (T).
For maximum shaft lengths of cut shafts (K), contact THK.
Note2) The dynamic permissible thrust (F) indicates the torque at which the contact surface pressure on the screw tooth surface is 9.8 N/mm².
The maximum axial load (both when stopped and during operation) is set to the dynamic permissible thrust or below, and it must be selected while taking into consideration the safety factors of Table1 on Selecting a Lead Screw Nut .
