DIN Standard compliant Ball Screw (DIN69051) Structure and Features In the DIN 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 EB of oversized-ball preload type or non-preloaded type, and model EP of offset preloaded type. [Compact] This Ball Screw is compactly built. Because of an internal circulation system using deflectors, the outer diameter of the nut is 70 to 80% of the conventional double nut and the overall nut length is only 60 to 80% of the return pipe nut. [Compliant with a DIN standard] The nut flange shape, mounting holes and rated load are compliant with DIN69051.

Note) The rigidity values in the table represent spring constants each obtained from the load and the Elastic Deformation finish 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 0.24 Ca, the rigidity value (KN) is obtained from the following equation.

Note) The rigidity values in the table represent spring constants each obtained from the load and the elastic deformation when providing a preload 8% of the basic dynamic load rating (Ca) and applying an axial load three times greater than the preload. 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 applied preload (Fa0) is not 0.08 Ca, the rigidity value (KN) is obtained from the following equation.
