The precision miniature ball nut SFK is ideal for applications that require high durability, miniaturization, positioning accuracy and smooth operation. All nuts have no axial play and have a preload of 0-2%, which reflects high rigidity. Tolerance C5-C7, nut material: SCM415H (hardness 58-62 HRC), steel ball material: SUJ2 (hardness +60 HRC), manufacturer: TBI Motion

Ball nuts and screws must be from the same manufacturer! Each nut is tested to fit the ball screw completely. If you order only nuts without a screw, we will not guarantee it.
