INDUSTRY COMPONENT

Alignment Pin

Precision alignment pin for beverage bottle conveyor guide rails ensuring accurate positioning and smooth bottle flow.

Component Specifications

Definition
A precision-engineered cylindrical component used in beverage bottle conveyor systems to maintain exact alignment between guide rail sections, prevent lateral movement of bottles during transport, and ensure consistent positioning for filling, capping, and labeling operations. It provides mechanical registration between modular conveyor segments.
Working Principle
The alignment pin operates on mechanical interference fit principles, where its precisely machined diameter matches corresponding bushings or holes in adjacent guide rail sections. When engaged, it eliminates play and maintains positional accuracy through rigid connection, preventing misalignment caused by vibration, thermal expansion, or operational loads.
Materials
Stainless Steel AISI 304 or 316, hardened to 45-50 HRC, with optional PTFE or ceramic coating for reduced friction. Corrosion-resistant for wet environments.

Frequently Asked Questions

What maintenance does an alignment pin require?

Regular inspection for wear, cleaning to prevent residue buildup, and lubrication if uncoated. Replacement when diameter wear exceeds 0.01mm.

Can alignment pins be used in high-speed bottling lines?

Yes, when manufactured to tight tolerances with appropriate materials, they maintain stability at speeds up to 800 bottles/minute.
