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.
According to the directory, axial load capacity ranges from 20 to 5000 kN, radial from 10 to 2500 kN, and tilting moment from 5 to 2000 kN·m. These are reference ranges; actual values depend on bearing size and design, so confirm with the manufacturer.
The directory lists high-carbon chromium bearing steel and alloy steel as materials. Raceways are induction hardened to 55–60 HRC. For specific material grades, consult the manufacturer.
The standard operating temperature range is -40°C to 85°C. For low-temperature applications, grease suitable for -50°C is available. Always verify suitability for your environment.
Sealing protection is rated IP54 to IP65 per IEC 60529. For harsh environments, additional seals can be provided. Confirm the required protection level with the manufacturer.
