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.
The assembly is manufactured from alloy steel and bearing steel, with a material grade of 40CrMo4 (DIN EN 10083) for high fatigue strength. These materials provide the necessary strength and wear resistance for industrial slitting operations.
The maximum operating speed is 3000–6000 rpm, depending on the specific model and application. This range is limited by bearing and balance grade considerations, and the actual speed must be confirmed with the manufacturer.
The runout (TIR) is ≤0.01 mm, as per ISO 1101. This is critical for cut quality and must be maintained through proper installation and maintenance.
The balance grade is G2.5 as per ISO 1940. This is required to minimize vibration and ensure smooth operation at high speeds. The actual balance grade should be verified for the specific model.
