Component Specifications

Definition
Stick connection pins are cylindrical mechanical fasteners designed for connecting structural elements in boom assemblies. They function as removable or permanent joints that transmit shear and tensile loads between connected parts while maintaining precise alignment. These pins typically feature tight dimensional tolerances, surface finishes, and material properties to withstand dynamic loading conditions common in material handling, construction, and industrial machinery applications.
Working Principle
Stick connection pins operate on the principle of interference or clearance fits within mating holes of connected components. They transfer mechanical loads through shear forces along their cylindrical surface, maintaining alignment through precise diameter-to-hole relationships. Some designs incorporate locking mechanisms (cotter pins, retaining rings, or threaded ends) to prevent accidental disengagement during operation.
Materials
Typically manufactured from alloy steels (AISI 4140, 4340), stainless steels (304, 316), or high-strength aluminum alloys. Heat treatment processes (quenching and tempering) achieve hardness levels of 28-32 HRC for steel pins. Surface treatments include zinc plating, black oxide coating, or hard chrome plating for corrosion resistance and wear protection.

Frequently Asked Questions

What is the difference between stick connection pins and regular bolts?

Stick connection pins are primarily designed for shear load transfer and alignment, while bolts are designed for clamping forces through tension. Pins typically have tighter tolerances and don't require threaded connections in their primary function.

How do I select the right stick connection pin for my boom application?

Consider load requirements (shear vs tensile), environmental conditions (corrosion resistance needed), required precision (tolerance grade), and whether the connection needs to be permanent or removable. Always consult engineering specifications and applicable standards.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
