SFE Series – Large-Lead High-Speed Ball Screw
The SFE series is specifically designed for high-speed, light-load linear motion, offering a significantly larger lead than the SFU series at the same shaft diameter, achieving greater linear displacement per revolution. This series is designed for complete assembly interchangeability with mainstream SFE series products, suitable for high-speed transfer modules, pick-and-place robots, packaging equipment, and other cycle-sensitive machinery. Available in C5 and C7 accuracy grades.
Key Features
- Assembly Replacement – Direct replacement of existing same-series assemblies; custom shaft ends per customer drawings
- Large Lead / High Speed – Lead range 20-100mm; 2-5x linear speed of SFU at same RPM
- High-Speed Recirculation – Optimized tube bend radius and ball fill ratio to suppress impact noise
- Low Heat Generation – Optimized for light loads; excellent temperature control for extended reciprocation
- C5 Accuracy Option – Maintains lead accuracy at high speed; ready for servo direct-coupling or belt replacement

Custom Manufacturing Available
Standard ball screws and linear guides don't always fit your design. Here's what RFU MOTION can customize based on your drawings:
- Shaft end machining — machined precisely to your drawing
- Screw length — cut to your exact requirement
- Preload — light, medium, heavy, or custom value
- Nut type — standard flange, special shape, or non-standard mounting interface
- Rail length — continuous cutting with end finishing (chamfer or grinding)
- Mounting holes — special thread sizes, hole spacing, or countersunk dimensions
Send us your drawing or specs — we'll deliver exactly what you need.
