Product Introduction
Ball Screw SFY is a precision-rolled ball screw designed for high-speed linear motion applications where transmission efficiency and cost-effectiveness are both critical. Manufactured through cold rolling forming technology, it achieves over 90% transmission efficiency with smooth, low-friction movement suited to continuous high-cycle operation. Standard diameter range covers 12mm to 50mm, with precision grades C5 and C7 available. Common blank sizes are kept in stock to support both sample requests and bulk orders with shorter lead times.
Key Specifications
Key Advantages
High Transmission Efficiency
Rolling contact structure significantly reduces sliding friction, lowering drive power consumption and long-term operating costs compared to conventional sliding screws.
01
Stable High-Speed Performance
The optimized ball circulation design prevents ball jamming, making this series reliable for continuous high-speed, high-cycle duty cycles.
02
Flexible End Machining
Custom shaft end processing, flange nuts, double nut configurations, and preload options are available to eliminate axial backlash and match your assembly requirements.
03
Cost-Effective for Volume Orders
Rolled manufacturing shortens production cycles relative to ground screws, offering a practical procurement option without sacrificing precision grade compliance.
04
Pre-Delivery Quality Inspection
Every finished Ball Screw SFY unit is tested for concentricity, pitch accuracy, and surface hardness before leaving the factory.
