Whether you're a maintenance technician, a workshop owner, or a hands-on maker running conveyor systems, finding the right roller chain in the right pitch and strand configuration shouldn't be a guessing game. This listing covers the most widely used ISO metric roller chain sizes — #60 (12A\/12B) and #80 (16A\/16B) — in both simplex (single-strand) and double-strand configurations, along with matching full buckle and half buckle connecting links.\u003c\/p\u003e\n\u003cp\u003eEach roller chain is constructed from carbon steel with precision-hardened pins, bushings, and rollers. The #60 series features a 3\/4\" (19.05mm) pitch, while the #80 series runs a 1\" (25.4mm) pitch. Chains are available in 1.5-meter lengths or as individual connecting links (full buckle or half buckle). Roller diameter and plate thickness conform to ISO 606 \/ ANSI B29.1 standards, with inner plate widths typically ranging from 9.5mm to 15.9mm depending on the series and strand count.\u003c\/p\u003e\n\u003cp\u003eThese roller chains are suited for a wide range of applications: agricultural equipment drive systems requiring a dependable #60 simplex chain replacement, industrial conveyor lines where a double-strand #80 roller chain handles elevated load demands, and light manufacturing machinery where a #60 or #80 connecting buckle link enables fast field repairs without breaking the full chain run.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e Compatible with standard ISO 606 and ANSI B29.1 sprockets.

Always match the chain designation to your sprocket's specification — a 12A chain will not seat correctly on a 12B sprocket and vice versa.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do I choose between simplex and double-strand chain?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eSimplex (single-strand) chains are suitable for standard power transmission drives where load requirements fall within the chain's rated capacity. Double-strand chains share the load across two rows of rollers, effectively doubling the working load limit without requiring a larger pitch. Choose double-strand when your drive torque exceeds the simplex rating or when you need added redundancy in a conveyor application.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the difference between a full buckle and a half buckle connecting link?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eA full buckle (also called a spring clip or snap link) uses a spring-steel clip to retain the outer plate — it is faster to install and remove, making it ideal for applications where the chain is frequently disconnected. A half buckle (cotter pin link) uses a split cotter pin for retention, providing a more secure lock that is less likely to vibrate loose under shock loads. For high-vibration or heavy-duty conveyor use, the half buckle is generally preferred.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eAre these chains compatible with my existing sprockets?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eThese chains are manufactured to ISO 606 and BS dimensional standards. They will fit any sprocket designed for the same pitch and strand count — for example, a #60 \/ 12A simplex chain fits a 12A simplex sprocket with 3\/4\" pitch. Verify your sprocket's pitch, strand count, and standard (ISO\/BS) before ordering to ensure correct engagement.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do I measure my existing chain to confirm the correct size?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eMeasure the distance between the centers of two adjacent pins — this is the pitch. A pitch of approximately 19mm confirms a #60\/12A\/12B chain; approximately 25.4mm confirms a #80\/16A\/16B chain. Also count the number of strands (rows of rollers) to determine simplex or double configuration. If the chain is worn, measure across multiple links and divide for a more accurate average pitch.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat maintenance does a roller chain require?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eRoller chains should be lubricated regularly with a chain-specific oil to reduce pin and bushing wear. Check tension periodically — excessive sag accelerates wear on both the chain and sprocket teeth. Inspect for elongation (chain stretch) by measuring a known number of links; replace the chain when elongation exceeds 1–2% of the nominal length. Always replace the sprocket when fitting a new chain if the sprocket teeth show visible wear.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I join two chain lengths together using a connecting link?\u003c\/summary\u003e\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. A full buckle or half buckle connecting link of the matching chain series (e.g., 12A full buckle for a 12A simplex chain) can be used to join two chain lengths or to close a loop after fitting. Ensure the connecting link's pitch and strand count match the chain exactly. For permanent or high-load installations, a half buckle (cotter pin) link is recommended over a spring clip for added security.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-cta\"\u003e\u003cp\u003e🛒 Select your Model, Chain Pitch, and Lengths \u0026amp;
