CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Kingpin/Pivot Pin.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
While often used interchangeably, kingpin typically refers to the primary vertical pivot in steering systems, while pivot pin is a broader term for any rotational axis component. In articulation joints, both terms describe the central rotational element.
Regular inspection every 500 operating hours or according to manufacturer specifications. Check for wear, corrosion, and proper lubrication. Replacement is typically required when wear exceeds 0.1 mm or when surface damage is visible.
High-pressure lithium complex grease (NLGI Grade 2) with extreme pressure additives. For high-temperature applications, synthetic polyurea greases are recommended. Lubrication intervals depend on operating conditions but typically range from 50-200 hours.
