C3 vs C5 — Which grade do you need?
Both grades use the same SD Series ball screw geometry. The grade determines positional accuracy and is chosen based on your application requirements.
HIGH PRECISION
C3
ISO Accuracy Class 3
Highest standard grade for demanding positioning applications where maximum accuracy is required.
- Travel deviation ≤ 23 µm per 300 mm
- Required for high-speed & high-accuracy CNC
- Lower thermal distortion under sustained load
- Tighter lead accuracy tolerance across full stroke
Typical applications
CNC machine tools, semiconductor equipment, precision measurement systems, medical devices
STANDARD
C5
ISO Accuracy Class 5
Versatile standard grade for the majority of automation and motion control applications.
- Travel deviation ≤ 52 µm per 300 mm
- Ideal for general automation & robotics
- Cost-effective for high-volume production
- Compatible with all SD Series configurations
Typical applications
Industrial automation, 3D printing, pick-and-place, packaging machinery, general motion control
