Steel Detachable Chain
Steel detachable chain is one of the oldest styles chains that are still in use today. Since the early 1900s steel detachable chains have been implemented in agricultural and industrial applications around the world. They stemmed from the original cast detachable chain design (patented in 1873) and are manufactured to be light-weight, economical, and durable. USA Roller Chain and Sprockets offers a high-quality line of Steel Detachable Chains (SDC) and
steel detachable sprockets. We also have attachments and the easy to use
steel detachable chain breaker! Our selection of American standard steel detachable chain is manufactured from a special hot-rolled strip steel that is heat-treated for increased strength and a longer wear life. This type of chain is designed for moderate loads and speeds, it is extremely easy to repair and install. Something important to note when installing and using steel detachable chain is that the closed end of the tab should always be towards the sprocket. We stock both painted and non-painted SDC chains so when ordering please specify which series you are looking for.

Pick a spot to do the disassembly and release any tension and tensioning devices on the equipment, it is recommended that the chain is straight for easiest dis-assembly.
Step 2:
Rotate chain to required position to allow for the barrel it to easily slide freely out of the hook portion of the chain.
Step 3:
Once the right position is reached it should be easy to dis-assemble the chain by simply sliding the barrel out and off to the side.

Besides the chain we also stock a complete line of attachments. These attachments below can be supplied as individual links or already assembled onto the chain in any configuration needed. Our steel detachable chain attachments are manufactured to the same standards as the chain so you don't lose tensile strength or integrity with the attachment link.
