THK Ball Screw EBA

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 defl ector embedded inside the nut to the adjacent raceway, and then circulate back to the loaded area. Thus, the balls perform infi nite rolling motion. Two types of nuts are available: model EB of oversized-ball preload type or non-preloaded type, and model EP of off set preloaded type.
