PowerTrac XPR 1000 - 0250 RH
Inch Ball Screw, Precision Rolled, XPR, 1.000" Ball Circle Diameter, 0.250" Lead, RH Thread
Nook Industries uses the latest in CNC thread rolling technology and state of the art CNC induction heat treatment to manufacture a rolled screw with accuracy approaching precision ground at a substantially lower cost. XPR screws fill the need for applications that don’t warrant the expense for ground screws but still require more precise positioning than that offered by commercial grade screws. All are offered with internally preloaded non-adjustable ball nuts with either an integral flange or an OD thread which allows for the use of a custom flange to fit a specific need.
For convenience, XPR screws can be supplied completely machined and assembled with nuts and EZZE-MOUNTS ready for assembly. Should a standard assembly not fit the application, Nook can machine the screw to your specific design requirements. Ball nut configurations can be engineered to application requirements.
When loading an SSN or PRN style ball nuts on an XPR ball screw, depending on the length of the ball screw, the preload condition may vary. The fit between the ball nut and ball screw will range from a slight clearance (~.0005") to no-lash clearance throughout the travel, which may cause a minimal variation in tare drag torque. If a full preload is required select an SGT ground ball screw instead.
