Standard Hollow Pin Roller Chain

Product Description

Our Hollow Pin Chains are designed for conveyor and transmission systems that require flexible attachment installation and easy system modification. Featuring hollow pins that allow quick insertion of cross rods or attachments, these chains provide high versatility and reliable performance.

Key Features & Benefits

• Integrated Attachment Platform: The hollow pin acts as a built-in mounting point, enabling quick, secure, and rigid installation of pins, rods, plates, or custom fixtures directly through the chain link.
• Simplified Assembly & Modification: Attachments can be added or removed at any point in the chain without breaking the chain itself, drastically reducing assembly time and maintenance complexity.
• High Structural Integrity: Manufactured from high-grade steel, the hollow pins are designed to maintain the chain's essential tensile strength and wear resistance while providing this added functionality.
• Design Flexibility: Enables the creation of custom conveyor, lifting, or transfer systems by attaching various components (e.g., flights, pushers, plastic blocks, brackets) at precise intervals.
• Dual-Purpose Performance: Functions efficiently as both a drive chain and the structural backbone of a conveying or positioning system.
• Wide Compatibility: Available in standard roller chain pitches (ANSI/ISO), ensuring seamless engagement with common sprockets.

Scope of Application

• Hollow Pin Chains are the ideal solution where a standard chain needs to "do more" than just transmit power:
• Modular Conveyor Systems: The core component for tabletop chains, mat top chains, and assembly line conveyors where rods connect adjacent chains or support slats.
• Specialized Material Handling: Used in bottling lines, canning systems, packaging machinery, and sorting equipment to carry, push, or position products.
• Automated Manufacturing: In automated assembly, testing, and painting lines as a carrier for fixtures and pallets.
• Agricultural Machinery: In harvesters and processing equipment for crop movement.
• Custom Machinery: Any application requiring precise, repeatable attachment of components to a moving chain.

Close cooperation with factories

We maintain deep, long-term partnerships with the factory around 20 years. The factory has strong mechanical and automated production capabilities which ensure stable quality and performance of the products.

Quality control

The factory's rigorous quality control process includes material spectroscopy analysis, in-process inspections, and final checks with Magnetic Particle Testing (MPT) to ensure every bucket is free from defects and meets our high standards. The details control process as below,

1. Incoming raw materials undergo random sampling and analysis using a microscope to ensure the chemical composition meets production requirements.

2. During the production process, QC staff conduct timely sampling to ensure products are defect-free and handle any abnormal quality issues that may arise.

3. The final step involves using a magnetic particle flaw detector on metal parts to detect hidden cracks or defects.

4. All finished metal parts are proportionally sampled and sent to the laboratory for mechanical performance tests, size measurement, and 100% manual surface quality inspection.

Why Choose Our Hollow Pin Chains?

• Maximized Versatility: Transforms a standard drive component into a customizable linear motion system.
• Reduced Total Cost: Eliminates the need for complex welding or separate attachment clamps, lowering parts count and assembly labor.
• Proven Durability: The hollow pin is rigorously tested to ensure it does not compromise the chain's load-bearing capacity or fatigue life.
• Engineering Support: Our team can assist in designing the optimal chain-attachment combination for your specific application, ensuring reliability and performance.
• Consistent Quality: Manufactured with the same precision and quality control as our premium roller chains, guaranteeing smooth operation and long service life.
