Precision Caged Ball Screw High Speed SDAN-V/SDAN-VX type Models SDAN-V / SDAN-VX 55 / 63
The preload method utilizes a combination of two ball screw nuts preloaded with spacers to eliminate backlash. The nut dimensions conform to ISO standards (ISO 3408). This type has improved axial rigidity in comparison with the Model SDA-V.
Model SDAN-VX is the full-ball type version of the Model SDAN-V.
DN value : 130000
Screw shaft diameter (mm) :
55,63

Notes on dimensional table
- Note) Models marked with an asterisk (*) in the specification table are only compatible with Model SDAN-VX (full-ball type).
- It is not possible to chamfer both ends of the screw shaft. When designing your system this way, contact THK.
The rigidity values in the table represent spring constants, each obtained from the load and the elastic deformation when providing a preload equal to 10% of the basic axial dynamic load rating (Ca) and applying an axial load three times greater than the pre-load.These values do not include the rigidity of the components related to mounting the ball screw nut. Therefore, it is normally appropriate to regard roughly 80% of the value in the table as the actual value.If the applied preload (Fa0) is not 0.1 Ca, the rigidity value (KN) is obtained from the following equation.
