Expert FAQ: Technical Terms & FAQ
Frequently Asked Questions for High Precision Ball Screw SFY1616 SFY2040 Series C3 C5 Ball And Screw
1. What do C3 and C5 precision grades mean?
C3 (precision class) specifies a lead error tolerance below 1μm per 300mm, suitable for high-precision CNC tools, while C5 allows up to 4μm error, fitting for most industrial machinery applications.
2. What is the material composition of these ball screws?
Primary screw shafts and balls are manufactured from GCr15 (AISI 52100) high carbon chromium alloy steel, hardened to 60–62 HRC after heat treatment for excellent fatigue and abrasion resistance.
3. What international standards do they comply with?
High Precision Ball Screw SFY1616 SFY2040 Series C3 C5 Ball And Screw comply with ISO 3402, ISO 9227 (corrosion), ISO 3290-2 (ball grade), ANSI B5.48, and, for custom medical variants, FDA material compliance.
4. What is static vs. dynamic load rating?
Dynamic load refers to the axial load a ball screw can endure for 1 million rotations before fatigue, while static load specifies the maximum load the stationary assembly can withstand without permanent deformation.
5. Can I order with custom dimensions or end machining?
Yes, both SFY1616 and SFY2040 models support custom lengths, machined ends (per your technical drawings or standard fitments), and special nut forms upon request.
6. What is the typical installation standard?
ISO 3408 is commonly referenced for ball screw mounting; centering and preload controls are essential for vibration-sensitive systems. End supports usually align with DIN 69051 or custom factory specification.
7. How does the product handle lubrication & maintenance?
OEMs recommend synthetic grease certified for high loads and corrosion, with regreasing intervals of 5000–8000 hours (subject to duty cycle and environment). Integrated seals and debris scrapers help reduce maintenance.
