| Feature Aspect | Description & Advantage |
|---|---|
| 1:1 Large Lead Design | Nominal diameter of 16 mm and lead of 16 mm, with a lead-to-diameter ratio of 1:1. Travel distance per rotation reaches 16 mm. Compared to small-lead specifications of the same diameter, it achieves higher‑speed linear motion, significantly improving equipment efficiency. |
| Compact Structure Design | The nut adopts an E‑type end cap circulation structure, resulting in a compact外形 with a small flange size (54×54 mm). Suitable for small equipment with limited space, such as desktop 3D printers and small laser marking machines. |
| Moderate Load Capacity | Dynamic rated load is approximately 800–1,000 kgf, optimized for high‑speed, light‑load applications. Provides reliable load capacity while maintaining speed, suitable for light to medium load applications. |
| High Rigidity & Backlash‑Free | Adopts a Gothic arch groove four‑point contact design, eliminating axial backlash through preload adjustment, ensuring high rigidity and precise positioning even under high‑speed operation. |
| High‑Efficiency Transmission | Rolling friction structure keeps driving torque below one‑third of that of sliding screws, with energy conversion efficiency reaching over 90%. It can be paired with low‑power stepper/servo motors, reducing energy consumption and operating costs. |
| E‑Type End Cap Circulation Structure | Uses an E‑type end cap circulator; balls are guided to return holes via the end cap. Features a compact structure and smooth operation. The advantage is a single nut design that suits high‑speed applications and saves installation space. |
| Excellent Durability | Manufactured from high‑quality bearing steel (GCr15/SUJ2), carburized and hardened to a surface hardness of HRC 58–62. Combined with precision machining processes, it delivers a long service life and high reliability. |
| Smooth & Quiet Operation | High motion efficiency and low heat generation result in extremely low starting torque, eliminating the "stick‑slip" phenomenon common with sliding screws. Runs smoothly and quietly at high speeds, suitable for noise‑sensitive environments. |
| Multiple Accuracy Grades | Available in various accuracy grades such as C3, C5, and C7. Grade C7 is suitable for general machinery, while Grade C5 and above are suitable for high‑precision positioning applications. |
Application Scenarios
The SFE1616 is particularly suitable for small equipment that requires rapid displacement under high-speed, light-load conditions:
| Application Field | Specific Equipment | Selection Rationale |
|---|---|---|
| 3D Printing & Additive Manufacturing | Desktop 3D printers, SLA 3D printers, small laser sintering systems | High-speed printing requires rapid positioning, and the compact size fits small equipment |
| Laser Processing Equipment | Small laser marking machines, laser engraving machines, small laser cutting machines | High-speed scanning positioning shortens processing cycles |
| CNC Equipment | Small CNC engraving machines, CNC routers, PCB drilling machines | Rapid idle positioning improves machining efficiency |
| Automation Equipment | Small XY tables, Cartesian robots, automatic screwdriving machines, dispensing platforms | High-speed pick-and-place and rapid positioning increase production line cycle times |
| Electronics & Semiconductor | Small wafer inspection stages, IC test sockets, pick-and-place machines | Precision high-speed positioning meets the high cycle rate demands of electronics manufacturing |
| Medical & Laboratory | Laboratory automated sampling platforms, diagnostic instruments, micromanipulation platforms | Smooth and quiet operation suitable for precision applications |
