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.
According to the directory, pivot bearing housings can be made from cast iron, steel, or aluminum alloy. The choice depends on the application's load, environmental conditions, and weight requirements. For gray cast iron, grades HT200–HT300 per GB/T 9439 are listed, offering strength and damping. Always confirm the specific material grade with the manufacturer for your application.
The bore diameter ranges from 20 to 100 mm, matching the pivot bearing's outer diameter. The bearing seat tolerance is H7 per ISO 286 to ensure a proper fit. These are reference ranges; the exact bore diameter must be matched to the specific bearing used in your assembly.
The operating temperature range is -20 to 80 °C. Beyond this range, material strength may be affected. It is important to verify that the housing material and design are suitable for your actual operating environment, as the directory values are reference ranges.
The parameters listed (bore diameter, outer diameter, height, tolerance, surface roughness, temperature, material grade, weight) are directory reference ranges. You must confirm the exact values with the legal manufacturer or supplier for your specific model and application. Also, ensure that any standards referenced (ISO 286, ISO 1302, GB/T 9439) are met by the actual product.
