Do you know Hollow Pin Chain？

1. What is a Hollow Pin Chain Hollow pin chain is a special conveyor chain with hollow pins instead of solid pins. It allows attachments, cross bars, or support shafts to be inserted directly into any link without disassembling the chain, making it highly flexible for material handling systems. 2. Core Advantages Easy attachment installation：Attachments can be mounted, adjusted, or replaced quickly without dismantling the chain. Stable conveying precision：Attachment spacing remains consistent whether running straight or engaging sprockets. Even load distribution：Load is equally shared by both side plates, reducing side sway and ensuring stable running. Lightweight & low noise：Lighter than solid‑pin chains with similar load capacity; quieter during operation. Convenient maintenance：Attachments can be cleaned, repaired, or re‑spaced while the chain remains installed. 3. Main Types Short Pitch Hollow Pin Chain Compact structure, high precision. Suitable for light loads and short‑distance conveying. Double Pitch Hollow Pin Chain Longer pitch, lighter weight. Ideal for medium to long conveying lines. Stainless Steel Hollow Pin Chain 304 / 316L stainless steel. Corrosion‑resistant, for food, pharmaceutical, and wet environments. Flange Roller Hollow Pin Chain Flanged rollers provide lateral guidance. Improves stability and prevents side shifting. Lube‑Free Hollow Pin Chain Oil‑impregnated bushings. Maintenance‑free for long operating periods. 4. Structure & Components Hollow pin：Central through‑hole for mounting attachments. Inner/outer plates：High‑precision stamped, fatigue‑resistant. Bushing：Supports roller, ensures smooth rotation. Roller：Reduces friction with sprockets; available in standard or flange type. 5. Typical Applications Automated assembly lines Packaging machinery Food processing and bottling lines Pharmaceutical conveying systems Logistics and sorting equipment Lines requiring frequent attachment changes 6. Operating Conditions Working temperature：-10°C to 150°C (standard carbon steel). Suitable for low to medium loads and low to medium speeds. Compatible with standard or dedicated sprockets based on roller type. 7. Selection Tips Choose short pitch for light loads and high precision. Choose double pitch for long‑distance conveying. Select stainless steel for corrosive or clean environments. Confirm attachment type, mounting spacing, and load before ordering. Prefer even number of links for better strength.
