SRT0604

features

• Material: PowerTrac™ Ball Screws are made of high quality alloy steel, induction hardened to RC 56-60. PowerTrac™ Ball Screws are given a protective black oxide finish. Selected sizes are available in heat-treated stainless steel (RC 40-45) for app
• LEAD ACCURACY PowerTrac™ Rolled Ball Screws will not deviate from nominal lead by more than 0.004 in/ft on screws through 2 1/2" diameter and 0.008 in/ft on screws 3" and over.
• STRAIGHTNESS PowerTrac™ SRT Ball Screws are straight within 0.010 in/ft when shipped from the factory, and do not exceed 0.030" in any 6' section. PowerTrac™ Ball Screws may require additional straightening after matching due to inherent stresses
• GOTHIC ARCH PowerTrac™ Ball Screws feature the gothic arch design that ensures component compatibility and long life.
• LIFE PowerTrac™ Ball Screws, like other antifriction bearings, have predictable life, based on material fatigue, if properly maintained.
• EFFICIENCY The low coefficient of friction of the rolling elements of the Ball Screw results in an operating efficiency of 90%.
• Backlash the axial movement between a new Ball Nut and Screw ranges from .003-.015" depending on size of bearing ball
• SURFACE COATINGS PowerTrac™ Ball Screws have a protective black oxide finish.
• Backdriving because of their high efficiency, PowerTrac™ Ball Screw Systems will backdrive, thus requiring a brake to hold the load
