Note 1)
All models are Right-hand screw.
Note 2)
The diameter of the Screw Shaft both ends must be less than the Screw Shaft Root diameter,
because of productlon and Nut assembly reason. If bigger end-journal than Shaft diameter is required, please consult ABSSAC.
Note 3)
Ball Nut dimension is without seal at the both ends. All type of Ball Nuts cannot equip with seals.
Note 4)
Rigidity
The Rigidity values shown in the table are theoretical values calculated from the amount of Elastic Displacement
under the Axial load equivalent to 30% of the Basic Dynamic Load Rating Ca.
Note 5)
Stainless Rolled Ball Screw
Stainless Rolled Ball Screw is available for Ball Nut Model Number marked **.
