Micro RV CAD
Start here for 1.5 mm to 12 mm miniature screws, finger-scale actuators, medical tools, and compact positioning axes.
View micro RV specsAccelerate your integration with RFQ-ready CAD request inputs, load/life calculation guidelines, and OEM selection parameters.
STEP and IGES files are provided after engineering review for applicable RV, ISR/RVi, and custom actuator envelopes. To protect program IP while supporting your design, submit a brief request so our engineers can send the correct parameterized geometry for your package instead of a mismatched catalog placeholder.
Detailed PDF catalogs covering buckling load limits, natural frequency, critical rotating speed, and lubrication guidelines for high-vacuum or cleanroom environments.

Compare the theoretical fatigue life (in millions of revolutions) between a standard ball screw and a planetary roller screw under your specific axial load.
Excellent: Roller screw design safely handles this load profile with massive life margins.
A useful CAD request needs enough context to avoid sending a model that fits the nominal screw size but fails the actuator package. Include the fields below when requesting STEP or IGES files.
| Input | Why It Matters | Common Gap |
|---|---|---|
| Diameter, lead, stroke, total length | Sets the base screw family and usable actuator envelope. | Stroke is provided without bearing stack or hard-stop space. |
| Nut style and mounting interface | Determines whether flanged, cylindrical, inverted, or custom nut geometry is practical. | Buyer requests a standard nut but housing space requires a custom form. |
| Load, speed, duty cycle, and life target | Drives fatigue life, heat, lubrication, and support-bearing assumptions. | Peak thrust is shared without continuous load or cycle rate. |
| Evidence and compliance needs | Aligns inspection reports, material certificates, and sample acceptance criteria before prototype release. | Quality files are requested after quote, changing scope and lead time. |
