Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
A drive nut converts rotary motion of a lead screw into linear motion, while a motor coupling connects two shafts to transmit torque and compensate for misalignment. Both are used in positioning stages but serve different functions.
Selection depends on motor torque, shaft diameters, speed, backlash requirements, and environmental conditions. Refer to the specified ranges (e.g., torque 0.5–50 N·m, shaft diameter 3–35 mm) and verify with the manufacturer for your application.
Regularly inspect for wear, backlash, and misalignment. Lubricate as recommended by the manufacturer. Replace if excessive play or vibration occurs to maintain positioning accuracy.
Depending on the IP rating (IP40–IP65), they can handle dust and moisture. For wet or dusty conditions, choose a higher IP rating. Always confirm with the supplier for specific environmental limits.
