Super Z Series
Super Z Series Miniature Cassette-Type Ballscrews
- Nut Configurations
- FSZ (single nut, flange)
- Nominal Diameter
- 6 - 32 mm
- Lead
- 2 - 5 mm
- Accuracy Grade
- JIS C0 - C10
Cassette-type circulation path improves speed and reduces noise and vibration. The nut's diameter is 15% – 30% smaller, making it perfect for smaller spaces.
-
15–30%
Smaller nut diameter than a conventional nut
-
160,000
Dm-N value for high-speed operation
-
1.5 G
Maximum acceleration
Applications
- Semiconductor equipment
- Inspection machines
- Medical equipment
- LCD manufacturing equipment
- Robots
- SPM
- Special environment machines
- Electric machinery
Nut configurations
FSZ is the one Super Z nut model: F flange end, S single nut, Z cassette-type circulation. It is offered precision ground (6–32 mm nominal diameter, 22 standard sizes) and precision rolled (6–20 mm, 24 standard sizes).

Accuracy grades
Super Z spans the full accuracy range: precision ground FSZ in C0 to C7, precision rolled FSZ in C6 to C10. Values are maximum lead variation over any 300 mm of travel.
- C0 3.5 µm per 300 mm — Precision ground
- C1 5 µm per 300 mm — Precision ground
- C2 6 µm per 300 mm — Precision ground
- C3 8 µm per 300 mm — Precision ground
- C4 12 µm per 300 mm — Precision ground
- C5 18 µm per 300 mm — Precision ground
- C6 23 µm per 300 mm — Ground or rolled
- C7 50 µm per 300 mm — Ground or rolled
- C8 100 µm per 300 mm — Precision rolled
- C10 210 µm per 300 mm — Precision rolled
Preload
FSZ is a single-nut model, so preload is set with oversized balls rather than a spacer or offset pitch. HIWIN's general guidance caps the heaviest preload at 10% of dynamic load C.
- - Oversized-ball preload — Slightly oversized balls give four-point contact for zero backlash in a compact single nut
