Inch Precision Accuracy Ball Nut Features

SGN STANDARD GROUND NUTS
(V-thread, no preload)

SGN precision ball nuts are similar to SBN style ball nuts and have internal threads that are ground into the ball nut body. These nuts provide smooth, precise operation on rolled thread or ground thread ball screws.

SAG STANDARD ADJUSTABLE PRELOAD NUTS
(Ground Ball Groove, Integral Flange and Wipers)

SAG ball nuts offer the precision tolerances of ground ball screw systems with the flexibility of adjustable preload.

PRN PRECISION INTERNAL PRELOAD NUTS
(V-thread end with wipers)

PRN precision ball nuts have a preload that is created by shifted internal threads that are ground. The resulting concentricity ensures uniform preload. PRN Precision ball nuts are compact and stiff due to the single nut integral preload configuration. Factory fitting on ball screws provides a backlash-free system with uniform torque, high stiffness and long life.

SSN PRECISION INTERNAL FLANGED PRELOAD NUTS
(Integral flange and wipers)

SSN precision ball nuts have the same features as the PRN nut design while incorporating an integral flange.
