Component Specifications

Definition
A pivot pin is a cylindrical mechanical component designed to serve as a rotational axis within locking mechanisms, allowing connected parts to pivot while maintaining alignment and load-bearing capacity. In industrial applications, it ensures precise angular movement, prevents lateral displacement, and withstands shear forces during operation.
Working Principle
The pivot pin functions as a fulcrum point, enabling rotational motion between two or more components in a locking mechanism. It distributes mechanical loads radially, reduces friction through proper clearance, and maintains structural integrity under dynamic or static conditions.
Materials
Typically manufactured from alloy steel (e.g., AISI 4140, 4340) or stainless steel (e.g., 316, 17-4 PH) for corrosion resistance and high strength. Surface treatments may include hardening (HRC 45-55), plating (zinc, nickel), or coating (black oxide) for enhanced durability.
Technical Parameters
  • Length 20-200 mm
  • Diameter 5-50 mm
  • Tolerance h7/g6
  • Load Capacity Up to 5000 N shear
  • Surface Finish Ra 0.8-1.6 μm
  • Operating Temperature -40°C to 120°C
Standards
ISO 8734, DIN 6325, ANSI B18.8.2
