INDUSTRY COMPONENT

Pivot Pin

A precision-engineered pivot pin used in locking mechanisms to enable rotational movement and secure positioning.

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.

Frequently Asked Questions

What is the primary function of a pivot pin in a locking mechanism?

It provides a fixed rotational axis, allowing parts to pivot while maintaining alignment and resisting shear forces.

How do I select the right pivot pin material?

Choose based on load requirements, environmental conditions (e.g., corrosion), and compatibility with mating parts; alloy steel for high strength, stainless for corrosion resistance.

What standards apply to industrial pivot pins?

Common standards include ISO 8734 for parallel pins, DIN 6325 for grooved pins, and ANSI B18.8.2 for dowel pins, ensuring dimensional accuracy and performance.
