FCD Series
Шарико-винтовые пары (ШВП) — Double Nut
Premium double-nut ball screw with преднатяг проставкой for нулевой люфт. C2/C3 ground precision with internal ball return, обеспечивая rigid and repeatable positioning for demanding CNC applications.
FCD Series / Шарико-винтовые пары (ШВП) — Double Nut
The FCD Series is Luoyang Songju's premium double-nut ball screw, featuring a преднатяг проставкой system that достигает нулевой люфт while maintaining smooth rotation and high efficiency. Two nuts are mounted in opposition with a прецизионно шлифованная spacer between them, applying a contground preload that устраняет осевой люфт without the torque variation inherent in spring-preloaded designs. This rigid preload method гарантирует consistent positioning accuracy throughout the screw's срок службы.
Ground to C2 or C3 класс точностиs with internal ball return circuits, the FCD Series обеспечивает exceptional repeatability for CNC machine tool axis drives. Доступно в diameters from 16mm to 80mm with ходs ranging from 5mm to 40mm, FCD ball screws are engineered for the most demanding positioning applications. The internal ball return design keeps the nut body compact while the double-nut configuration обеспечивает higher грузоподъёмность and жёсткость than single-nut alternatives. Идеально для CNC lathe and обрабатывающий центр axis drives, grinding machine feed axes, and precision assembly automation.

Почему выбирают FCD Series Шарико-винтовые пары (ШВП)
The FCD Series combines zero-backlash double-nut preload with ground precision for applications where positioning accuracy, жёсткость, and long срок службы are non-negotiable.
Zero Backlash
Spacer preload system устраняет осевой зазор completely, providing consistent двунаправленная positioning without torque variation across the full stroke length.
Double Nut Жёсткость
Two nuts in opposition double the load-carrying ball contact points, обеспечивая significantly higher axial and radial жёсткость than single-nut ball screws.
Ground Precision
C2 or C3 ground класс точностиs ensure exceptional точность хода and repeatability, meeting the exacting positioning requirements of high-end CNC machine tools.
Internal Ball Return
Integrated ball recirculation paths keep the nut body diameter compact, enabling installation in space-constrained machine designs without sacrificing performance.
Высокая грузоподъёмность
Double-nut architecture распределяет axial forces across two independent шариковая цепьs, substantially increasing dynamic and статическая нагрузка ratings over single-nut equivalents.
Длительный срок службы
Precision-ground raceways, contground preload, and effective sealing combine to deliver exceptional durability in continuous-production CNC environments.
