06B–32A Simplex & Duplex Roller Chain Connecting Links — Precision-Fit for Drive Systems When a worn or broken connecting link brings your conveyor, drive shaft, or machinery to a halt, every minute of downtime costs you. Whether you're a maintenance engineer keeping production lines running or a DIY mechanic rebuilding a drive system, you need a connecting link that fits precisely, installs without guesswork, and holds under load. These simplex and duplex roller chain connecting links are engineered to match standard roller chain dimensions across a wide size range — from compact 06B to heavy-duty 32A. Each link is manufactured from carbon steel with a zinc-plated or natural finish depending on variant, designed to meet ISO/DIN roller chain standards. The range covers chain pitches from 1/4" (6.35 mm) through 2" (50.8 mm), with both Full Buckle Join (clip-type) and Half Buckle Join (cotter pin-type) configurations available. Sizes span 06B, 08B, 08A, 10A, 12A, 16A, 20A, 24A, 28A, and 32A to cover the most common simplex and duplex roller chain standards. Typical applications include industrial conveyor roller chain repair, agricultural machinery drive chain maintenance, go-kart and motorcycle chain replacement, and general power transmission equipment servicing. Whether you're sourcing a single replacement link for a simplex roller chain connecting link repair or stocking spares for a duplex drive chain system, this range covers the most widely used sizes in one listing. 🔗 Compatible with ISO/DIN standard simplex and duplex roller chains — sizes 06B through 32A, pitches 1/4" to 2". Verify your chain pitch and width before ordering. ✅ Key Features of These Simplex & Duplex Roller Chain Connecting Links 📐 Wide Size Coverage (06B–32A) — Covers ten standard roller chain sizes in a single listing, from the compact 06B (1/4" pitch) up to the heavy-duty 32A (2" pitch), reducing the need to source from multiple suppliers. 🔩 Two Join Types Available — Choose Full Buckle Join (spring clip / snap link) for fast tool-free installation, or Half Buckle Join (cotter pin type) for a more secure, vibration-resistant connection in demanding applications. 🏗️ Carbon Steel Construction — Made from carbon steel to deliver the tensile strength and wear resistance required for power transmission and conveyor drive applications across industrial and agricultural environments. 🛡️ Corrosion-Resistant Finish — Surface treatment provides a protective layer against rust and oxidation, extending service life in moderately humid or outdoor environments compared to bare steel links. 📏 ISO/DIN Dimensional Compliance — Manufactured to match standard roller chain pitch, inner width, and plate thickness tolerances, ensuring drop-in compatibility with existing simplex and duplex chain runs without modification. 🔄 Simplex & Duplex Compatible — Suitable for both single-strand (simplex) and double-strand (duplex) roller chain configurations, making these links versatile for a broad range of drive and conveyor system repairs. 📐 Technical Specifications — Roller Chain Connecting Links Chain Standard ISO/DIN Roller Chain Size Range 06B, 08B, 08A, 10A, 12A, 16A, 20A, 24A, 28A, 32A Pitch Range 1/4" (6.35 mm) – 2" (50.8 mm) Chain Type Simplex (single-strand) & Duplex (double-strand) Join Type Full Buckle Join (spring clip) / Half Buckle Join (cotter pin) Material Carbon Steel Surface Finish See variant options Inner Width See variant options Plate Thickness See variant options Breaking Load See variant options Packing Quantity 1 pc per unit Weight See variant options ❓ Frequently Asked Questions How do I choose the correct connecting link size for my roller chain? Match the connecting link size to your existing chain's pitch and strand count. The pitch is the distance between the centers of two adjacent pins — measure this with a ruler or caliper across several links and divide by the number of pitches for accuracy. Common sizes: 06B = 3/8" pitch, 08B/08A = 1/2" pitch, 10A = 5/8" pitch, 12A = 3/4" pitch, 16A = 1", 20A = 1-1/4", 24A = 1-1/2", 28A = 1-3/4", 32A = 2". Also confirm whether your chain is simplex (single-strand) or duplex (double-strand) before ordering. What is the difference between Full Buckle Join and Half Buckle Join? A Full Buckle Join uses a spring clip (snap link) to retain the outer plate — it installs and removes quickly without tools, making it ideal for applications where the chain needs periodic removal. A Half Buckle Join uses a cotter pin through the link pin for retention, which provides a more positive lock and is preferred in high-vibration or heavy-load applications where a spring clip could work loose. Choose Full Buckle for convenience; choose Half Buckle for security. Are these connecting links strong enough for industrial conveyor use? These links are manufactured from carbon steel to match the tensile strength requirements of standard ISO/DIN roller chains. For industrial conveyor applications, ensure the link's rated breaking load meets or exceeds your system's working load with an appropriate safety factor (typically 7:1 or higher for continuous-duty conveyors). For specific breaking load values by size, please contact us to confirm before ordering for critical load-bearing applications. Will these links work in outdoor or humid environments? The surface treatment on these links provides moderate corrosion resistance suitable for indoor industrial environments and light outdoor exposure. For continuously wet, marine, or chemically aggressive environments, consider applying a chain lubricant or grease after installation to extend service life. For severe corrosion environments, stainless steel connecting links may be more appropriate — contact us if you need guidance on material selection. Are these links compatible with both simplex and duplex chains? Yes. The listing covers connecting links for both simplex (single-strand) and duplex (double-strand) roller chain configurations. When selecting your variant, confirm the chain type (simplex or duplex) in addition to the size and join type. A simplex link will not fit a duplex chain of the same pitch, as the inner width and plate configuration differ between the two strand counts. How do I install a roller chain connecting link correctly? For a Full Buckle Join: thread the link pin through the chain ends, fit the outer plate over the pin ends, then press the spring clip into the grooves on the pin ends with the closed end of the clip facing the direction of chain travel. For a Half Buckle Join: thread the link pin through the chain ends, fit the outer plate, then insert the cotter pins through the holes in the pin ends and bend them outward to lock. Always ensure the spring clip or cotter pins are fully seated before running the chain under load. Can I use a single connecting link to join two different chain sizes? No. Connecting links are size-specific and must match the pitch, inner width, and plate dimensions of the chain being joined. Mixing sizes creates a mismatch in pin diameter, plate hole size, or pitch spacing that will cause the link to fail under load or prevent proper engagement with the sprocket. Always use a connecting link that exactly matches your chain's size designation. 🛒 Select your chain size and join type above, then add to cart. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "How do I choose the correct connecting link size for my roller chain?", "acceptedAnswer": { "@type": "Answer", "text": "Match the connecting link size to your existing chain's pitch and strand count.
