When a worn or broken connecting link brings your conveyor, drive system, or industrial equipment to a halt, every minute of downtime costs you. Engineers, maintenance technicians, and serious DIYers who work with duplex roller chains need a replacement link that installs quickly, holds under load, and won't corrode in wet or chemically exposed environments. These A2 stainless steel duplex roller chain connecting links are engineered for exactly that situation.
Each connecting link is machined from A2 (AISI 304) stainless steel, offering solid corrosion resistance across a wide range of environments. Available in duplex full link buckle, duplex half link buckle, and three-row full link buckle styles, these links cover pitches from 9.525 mm (3/8 in) on the 06B-2 up to 31.75 mm (1-1/4 in) on the 20A-2, with the 08B-3 three-row variant at 12.7 mm (1/2 in) pitch. Sold in quantities of 1, 2, or 5 pieces per order.
Typical applications include food-processing conveyor lines where wash-down resistance is required, agricultural machinery exposed to moisture and fertilizer residue, marine deck equipment subject to salt-air corrosion, and general industrial drive systems where standard carbon-steel links corrode prematurely. The duplex (double-strand) configuration doubles the load capacity compared to a single-strand link of the same pitch, making these connecting links a reliable choice for duplex roller chain replacement and repair.

A full link buckle (spring clip connecting link) replaces a standard link and keeps the chain at the same length — use this for most repairs. A half link buckle (offset connecting link) adds half a pitch to the chain length, which is useful when you need to shorten or lengthen a chain by one half-pitch increment and a full link would leave the chain too tight or too loose. Check your chain tension requirements before selecting.
Match the model number on your existing chain or sprocket specification. The letter prefix indicates the standard: B-series (e.g., 06B-2, 08B-2) follows ISO 606 (common in Europe and Asia), while A-series (e.g., 08A-2, 10A-2) follows ANSI B29.1 (common in North America). The number before the letter indicates the pitch in sixteenths of an inch (e.g., 08 = 8/16 = 1/2 in = 12.7 mm). The "-2" suffix denotes duplex (double-strand).
A2 (AISI 304) stainless steel offers good tensile strength for moderate-load conveyor and drive applications. It is not as strong as hardened carbon steel under very high dynamic loads, but it significantly outperforms carbon steel in corrosive environments. For heavy-duty, high-speed, or shock-load applications, verify the rated working load of the specific model against your system requirements. Contact us to confirm tensile ratings for your selected model.
Yes. A2 (AISI 304) stainless steel provides solid resistance to water, humidity, mild acids, and salt-air exposure, making these links suitable for food-processing wash-down lines, agricultural equipment, and marine deck applications. For highly chlorinated environments or strong acid/alkali exposure, A4 (AISI 316) stainless steel would offer superior resistance — contact us if you need A4-grade links.
No. These are duplex (double-strand) connecting links designed specifically for two-strand roller chains. The inner plate width, pin length, and overall geometry are sized for duplex chains. Using a duplex link on a simplex chain will result in incorrect fit and potential failure. For simplex chain connecting links, please search our catalog for the corresponding simplex model.
The 08B-3 is a triple-strand (three-row) connecting link for 08B-3 roller chains with a 12.7 mm pitch. Triple-strand chains are used in high-torque, high-load drive systems where duplex capacity is insufficient — common in heavy agricultural machinery, industrial presses, and large conveyor drives. Ensure your sprocket is also rated for triple-strand 08B-3 chain before ordering.
For planned maintenance, ordering the 5 PCS pack provides the best per-unit value and ensures you have spares on hand for unplanned breakdowns. The 2 PCS pack suits smaller operations with infrequent chain repairs. The 1 PCS pack is ideal for a one-time repair or to verify fitment before stocking up. Select your preferred quantity in the Amount option above.
