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 wheel diameter range is 200–600 mm, as listed in the directory. This range determines load capacity and rail compatibility. For a specific application, you must confirm the exact diameter with the manufacturer or supplier.
The bearing type is spherical roller bearings, with sizes ranging from 22310 to 22324, per DIN 635. These bearings accommodate misalignment and are suitable for heavy loads. Verify the exact bearing size for your model.
The maximum wheel load is 10–50 tons, as per the directory. Exceeding this limit may cause rail deformation. Always confirm the load rating for your specific configuration with the manufacturer.
The wheel material is 65Mn per GB/T 1222, and hardness is 280–350 HB per GB/T 699. These standards are reference points; ensure your supplier provides compliance documentation for the actual product.
