The standard ball nut FSW (DIN 69051, Form B) is ideal for applications that require high durability, positioning accuracy and smooth operation. Ball nuts and screws must be from the same manufacturer! Each nut is tested to fit perfectly on a ball screw. We recommend ordering both ball nuts and ball screws. Otherwise, we cannot guarantee proper cooperation.
All nuts have no axial play and preload of 0-2%, which reflects high rigidity. Nut material: SCM415H (hardness 58-62 HRC), steel ball material: SUJ2 (hardness +60 HRC), producer: HIWIN
