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.
It converts the rotary motion of servo motors into precise linear movement of the machine axes, ensuring accurate positioning and repeatability.
Common materials include high-carbon chromium bearing steel (e.g., GCr15), case-hardened steel, and stainless steel for corrosion resistance.
Accuracy grades range from C3 to C7 per ISO 3408, with C3 for high precision and C7 for general use. The specific grade must be confirmed for the application.
Always check the manufacturer's datasheet or consult the legal supplier to confirm model-specific values such as diameter, lead, load ratings, and accuracy grade.
