If you're maintaining a line shaft conveyor, you might be weighing two very different power transmission components: a single Tsubaki roller chain and a pair of Delrin sprocket couplers. Both sit in the bearings, couplings, and power transmission aisle, but they solve different jobs. The chain replaces a worn drive chain; the couplers link sprockets along the line shaft. Both parts are new and made in the United States. So the decision isn't about which part is better overall-it's about which part your conveyor actually needs.
Quick Verdict
If the wear is in the chain itself, the Tsubaki roller chain is the direct fix. If the wear is in the sprocket connection, the Delrin coupler set is the more complete solution.

|---|---|---|---|
| NEW TSUBAKI H60B13F-1 1/4 ROLLER CHAIN power Transmission Components | USD 36.00 | A single roller chain from Tsubaki | Replacing a worn chain in a power transmission drive |

Where the Tsubaki Chain Wins
The Tsubaki roller chain is the only actual chain in this pair. If your line shaft conveyor's drive chain has stretched, snapped, or worn out, this part matches the replacement job directly. It carries the Tsubaki part number H60B13F-1 1/4.
Where the Delrin Coupler Wins
The Delrin coupler set is the specialized choice for joining sprockets on a line shaft conveyor. It comes with lock pins and fits the most common sprocket size used in that application. The install is cleaner than a steel chain coupler because there's no grease to fight.
Product Notes
NEW TSUBAKI H60B13F-1 1/4 ROLLER CHAIN power Transmission Components
This is a new Tsubaki roller chain with part number H60B13F-1 1/4. If you need to replace a worn drive chain, this is a direct fit for that job. It's a straightforward replacement choice. The trade-off is that this item comes from surplus inventory, so the exact chain in the photo may not be the one shipped, and it may show storage wear. That's a typical detail with surplus stock. If you want a part with a perfectly clean handling history, this might give you pause. For a maintenance replacement, it's a practical option.
Delrin Coupler Plastic Sprocket Coupling Chain for Line Shaft Conveyor - Qty 2
This set includes two Delrin couplers with lock pins. They're made for line shaft conveyors and fit two 4016 sprockets, the most common sprocket size used in that setup. The main draw is a clean install: align the sprockets, wrap the coupler around the teeth, and push the lock pin through. No grease, no fiddly small parts. The limitation is scope. This only handles sprocket-to-sprocket coupling, so it won't replace a roller chain. If your actual failure is a broken chain, this part won't help no matter how easy it is to install.
Final Choice by Use Case
Choose the Tsubaki roller chain if you need to replace a worn drive chain in a power transmission drive. Choose the Delrin coupler set if you need to connect sprockets on a line shaft conveyor. Each part is built for a different failure point, so the right pick depends on what actually wore out. Match the component to the job, and you'll get the fix your line needs.
