Backlash type |

- 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 the both ends. All type of Ball Nuts cannot equip with seals.
- Note 3)
- The Rigidity values shown in the table are theoretical values of Ball Nut Rigidity calculated from the amount of Elastic Displacement under the following conditions.

Backlash type ; Apply the Axial load equivalent to 30% of the Basic Dynamic Load Rating Ca.

Preload type ; Apply the Preload equivalent to 5% of the Basic Dynamic Load Rating Ca.

For Axial load or Preload condition other than the above,

see the formula in p-A823, you can calculate Rigidity using this formula. - Note 4)
- All models are Right-hand Screw. If Left-hand Screw is required, please ask ABSSAC representative.
- Note 5)
- Basic Load Rating and Rigidity for Backlash type and Preload type are described in the same cell.
