Expert FAQ: Technical Terms for DFU Ball Screw C3 Ball Screw And Double Nut
Q1: What is the main advantage of using a double nut system for ball screws?
A: The double nut design effectively eliminates axial backlash by preloading against each other. This results in higher positioning accuracy and stability, essential in applications requiring micron-level precision (Source).
Q2: Why is C3 precision grade important in modern industry?
A: C3 is an ISO/GB recognized precision class, guaranteeing lead deviation under 8μm per 300mm. This ensures ultra-smooth, consistent motion, which is vital for high-end CNC, semiconductor, and aerospace equipment.
Q3: What is the commonly used material for DFU ball screws?
A: High carbon chromium bearing steel (GCr15, equivalent to AISI 52100) is most common, featuring through-hardened or induction-hardened surfaces for abrasion and fatigue resistance.
Q4: How is preloading achieved in DFU Ball Screw C3 Ball Screw And Double Nut?
A: By assembling two nuts with an intentional offset or spacer, tension is created that cancels axial clearance, delivering close-to-zero backlash—a necessity for precision automation.
Q5: What is internal ball circulation and why does it matter?
A: The internal ball circulation system (circular/elliptical reversers) allows the recirculation path to stay within the nut body, reducing noise, size, and risk of contamination compared to external tube circuits.
Q6: Are there industry standards for installation fit and tolerance?
A: Yes. Ball screws comply with international standards like ISO 3408 and GB/T 17587.3, ensuring compatibility in mounting, preloading, and axial alignment.
Q7: How is lubrication handled in these systems?
A: Lubrication can be via conventional grease, automatic oilers, or oil-mist systems. Proper lubrication prolongs service life, reduces heat, and ensures peak performance.
