Precision Caged Ball Screw High Speed Model SBN-V Model SBN-V Midium

The circulation structure feature allows the balls to be picked up tangential to the direction of movement. The circulation components have been strengthened, increasing the DN value to 160,000 (small type: 130,000).

DN value : 160000
Screw shaft diameter (mm) : 25,28,32,36,40,45,50

Notes on dimensional table

Note) The overall length of the nut will increase when equipping the QZ lubricating device. See Dimensions of Each Model with an Option Attached for further details.
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 (K_N) is obtained from the following equation.
