Advantages of Hollow Pin Chains

1. Extremely High Flexibility in Attachment Installation
   The core advantage of hollow pin chains lies in their hollow pin structure, which allows attachments (such as crossbars, baffles, push plates, etc.) to be directly inserted into the hollow pins of any chain link without disassembling the chain or damaging the link structure. In contrast, if regular chains need to be fitted with attachments, they often require custom special links or modifications through welding, drilling, etc., which is cumbersome and may affect chain strength.
2. Greater Convenience in Maintenance and Adjustment
   Since attachments can be flexibly inserted and removed, during production line adjustments, attachment replacements, or maintenance, hollow pin chains do not require disassembly of the entire chain, significantly reducing downtime. For regular chains, once attachments are fixed, adjustment or replacement requires disassembling links, which is a tedious process.
3. Wider Structural Adaptability
   Hollow pin chains can be fitted with different types of attachments at any position according to conveying needs, easily adapting to scenarios involving irregular materials or multi-specification product conveying (such as sorting lines and packaging lines). Attachments on regular chains have fixed positions and are difficult to adjust flexibly.
4. Some Designs Combine Strength with Lightweight
   High-quality hollow pin chains use seamless tube hollow pins. Through optimized interference fit and press-fit force design, they reduce self-weight while ensuring connection strength, avoiding performance degradation caused by the "hollow" structure.

Disadvantages of Hollow Pin Chains

1. Slightly Lower Load-Bearing Capacity Than Same-Spec Regular Chains
   The cross-sectional area of hollow pins is smaller than that of regular solid pins. Under extreme heavy loads or impact conditions, their tensile and shear resistance may be slightly inferior to regular chains of the same material and specification. Therefore, hollow pin chains are more suitable for medium to light load conveying rather than heavy-duty power transmission.
2. Higher Cost
   The manufacturing process of hollow pins (such as seamless tube cutting and precision forming) is more complex than that of solid pins, and they need to be matched with specially designed chain plates, resulting in higher production costs than regular chains. For scenarios without attachment requirements, their cost-effectiveness is lower.
3. Higher Requirements for Cleaning and Lubrication
   The internal holes of hollow pins may accumulate dust, debris, or corrosive media. Improper maintenance can easily lead to pin wear or jamming. In contrast, regular solid pins have a lower risk of contaminant accumulation and are relatively easier to maintain.
4. Slightly Weaker Stability at High Speeds
   The hollow structure may cause slight vibration or noise during high-speed transmission, while the solid pins of regular chains have higher rigidity and better high-speed stability.
