FYD Series
Шарико-винтовые пары (ШВП) — Double Nut, External Return
The ultimate ball screw combining external трубка возврата грузоподъёмность with double-nut нулевой люфт. C2/C3 ground for the most demanding precision machining applications.
FYD Series / Шарико-винтовые пары (ШВП) — Double Nut, External Return
The FYD Series combines the high грузоподъёмность of external ball recirculation tubes with the zero-backlash performance of a double-nut preload configuration. Two nuts are precision-matched with a spacer element that applies contground preload, eliminating осевой зазор while the external tube design simultaneously позволяет maximum ball diameters for superior load ratings. This dual-benefit architecture makes FYD the highest-capacity zero-backlash ball screw in Luoyang Songju's product line.
Ground to C2 or C3 accuracy, FYD ball screws deliver the positioning precision required by high-end CNC grinding machines, precision boring mills, and ultra-accurate positioning stages -- all while supporting the тяжёлое резание forces these applications generate. Доступно в diameters from 20mm to 80mm with ходs from 5mm to 32mm. The external tube design обеспечивает easy access for inspection and maintenance, reducing long-term service costs in high-utilization production environments.

Почему выбирают FYD Series Шарико-винтовые пары (ШВП)
The FYD Series represents the pinnacle of ball screw engineering — combining zero-backlash double-nut preload with the high грузоподъёмность of external recirculation tubes for the most demanding CNC applications.
Zero Backlash + High Load
The unique dual-benefit design устраняет осевой люфт while simultaneously maximizing грузоподъёмность — a combination no single-nut or internal-return screw can match.
Double Nut Преднатяг
Two precision-matched nuts with a contground spacer apply uniform preload across the full stroke, eliminating backlash without introducing torque variation.
External Tube Access
External recirculation tubes allow quick visual inspection and maintenance without disassembly, reducing service time and extending operational availability.
Ground Precision
C2 or C3 ground accuracy гарантирует the positioning repeatability required by high-end CNC grinding and boring applications with sub-micron tolerances.
Maximum Жёсткость
The dual-nut configuration combined with the largest possible ball diameters обеспечивает the highest axial and radial жёсткость available in any Songju ball screw series.
тяжёлые Sealing
Reinforced wiper seals protect the прецизионно шлифованная raceways from coolant, swarf, and abrasive dust in the most aggressive production machining environments.
