- 1171-0413 Right Hand Standard Ball Nut With 1.967-18 NF-3 External Thread.
description
- PowerTRAC™ standard ball nuts are manufactured to match PowerTRAC™ ball screws. High efficiency is achieved through the use of recirculating bearing balls added between the nut and screw to eliminate sliding friction.Life of the assembly is determined by predictable fatigue cycles, not unpredictable frictional wear.
features
- SELECTIVE FIT Single SBN ball nuts can be custom fitted with selected bearing balls to minimize backlash to within .003".
- PRELOAD Preload is the internal load introduced between two ball nuts that eliminates axial and radial movement. This provides zero backlash for accurate repeatability. Preloaded ball nuts offer increased system stiffness. PowerTrac™ has a varie
- SURFACE COATINGS PowerTrac™ ball nuts have a protective black oxide finish.
- WIPER KITS It is recommended that PowerTrac™ brush or felt wipers be used with SBN Ball Nuts to prevent foreign materials from entering ball nuts. PowerTrac™ recommends bellows boots or metal covers for environments where abrasive particles or met
- EFFICIENCY The low coefficient of friction of the rolling elements of the PowerTrac™ ball nut results in an operating efficiency of 90%.
- Material: PowerTrac™ ball nuts are made of carburized steel with ball tracs heat-treated to Rc 58-60. Ball nuts are given a protective black oxide finish. Selected sizes are available in heat-treated stainless steel (RC 40-45) for applications in c
- Backlash the axial movement between a new PowerTrac™ SBN Ball Nut and Ball Screw ranges from .003 to .015" depending on size of bearing ball
