Note 1)
The diameter of one of the Screw Shaft ends must be less than the Screw Shaft Root diameter,
otherwise Ball Nut cannot be installed.
Note 2)
Ball Nut dimension is without seal at both ends.
If the seals are required, Ball Nut dimension should be changed, in that case, please ask ABSSAC.
Some type of Ball Nuts cannot equip with seals, please ask ABSSAC representative.
Note 3)
Rigidity
The Rigidity values shown in the table are theoretical values calculated from the amount of Elastic Displacement
under the Preload equivalent to 10% of the Basic Dynamic Load Rating Ca.
Note 4)
All models are Right-hand screw. If Left-hand screw is required, please ask ABSSAC representative.
