Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
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.
The rated load capacity per joint is typically between 5 and 50 tonnes, depending on the size and design. Always verify the exact capacity for your specific model with the manufacturer.
The typical rotation angle is ±90 degrees, allowing the boom to articulate within that range. Confirm the exact angle for your application, as it may vary.
The operating temperature range is -20°C to 80°C. Seals degrade above 80°C, so ensure the joint is not exposed to higher temperatures.
Inspection frequency depends on usage and manufacturer recommendations. Regular checks for wear, lubrication, and seal integrity are essential. Under rated load and proper lubrication, service life is 10,000 to 20,000 cycles.
