ISO 3408 Compliant EBB-V Model EBB-V 16/20/25/28/32/36

In the ISO standard compliant Ball Screw, balls under a load roll in the raceway cut between the screw shaft and the nut while receiving the axial load, travel along the groove of a deflector embedded inside the nut to the adjacent raceway, and then circulate back to the loaded area. Thus, the balls perform infinite rolling motion.
Two types of nuts are available: model EBB-V of oversized-ball preload type or non-preloaded type, and model EPB-V of offset preloaded type.

DN value : 130000
Screwshaftdiameter(mm) : 16,20,25,28,32,36

Notes on dimensional table

Note: When the QZ Lubricator and W wiper ring are attached, the overall length of the nut dimensions will increase. Contact THK for details.

Note)
The rigidity values in the table represent spring constants each obtained from the load and the elastic deformation when providing an axial load 24% of the basic dynamic load rating (Ca).
These values do not include the rigidity of the components related to mounting the nut. Therefore, it is normally appropriate to regard roughly 80% of the value in the table as the actual value.
If the axial load (Fa) is not 30% of Ca, the rigidity value (K_N) is obtained from the following equation.
