Q: What is the difference between C5 and C7 accuracy classes in ball screws?C5 represents a higher precision grade with tighter tolerances on lead and diameter, suitable for high-accuracy machinery, while C7 is a standard industrial grade suitable for general-purpose linear motion.
Q: How does the SFA series handle dust and contaminants?The SFA series features an advanced dust-prevention design that seals the ball nut and screw interface, preventing debris from entering the raceways and causing premature wear.
Q: Can the 1000mm length be customized for specific projects?Yes, while 1000mm is a standard offering, we provide customized cutting and machining services to meet the exact length requirements of your specific linear module.
Q: In which industries is the SFA rotary grade ball screw most commonly used?It is widely used in CNC milling machines, precision medical equipment, semiconductor manufacturing, and automated assembly lines where quietness and rigidity are critical.
Q: How do I maintain the rigidity of my ball screw over time?Regular lubrication with high-quality industrial grease and ensuring proper alignment during installation are key to maintaining high rigidity and reducing friction.
Q: Why is low noise an advantage in linear motion systems?Low noise usually indicates smoother ball circulation and lower vibration, which translates to higher precision and a more stable operating environment for sensitive components.
