Description
When your grain elevator, conveyor, or feed handling system snaps a chain during the busiest part of the season, you need a fix that’ll get you back running fast. This Diamond #140H heavy plate connecting link lets you repair or join chain sections without replacing an entire expensive chain run—turning what could be a costly breakdown into a quick repair that keeps your operation moving.
What You’re Getting
- Heavy-duty carbon steel construction built to handle the loads and abuse of agricultural equipment
- Precision-manufactured to ANSI #140 standards with 1-3/4 inch pitch for proper fit and strength
- Single strand design with 1-inch roller diameter that matches standard #140 chain specifications
- Reliable connection that restores full chain strength when properly installed
Built for Real Farm Work
This connecting link is sized for the heavy-duty chain systems you’ll find on larger grain elevators, feed conveyors, manure handling equipment, and other agricultural machinery where #140 chain is the standard. Whether you’re moving corn to the bins, handling feed in a livestock operation, or running conveyor systems in a grain facility, this link handles the constant cycling and heavy loads that come with the job.
Made to Last
Diamond builds this connecting link from carbon steel that’s engineered to match the strength and durability of the chain it’s joining. The heavy plate construction distributes stress properly across the connection point, while the precision manufacturing ensures smooth operation through sprockets and guides without binding or premature wear.
Good to Know
Always relieve chain tension completely before installing any connecting link—chains under load can cause serious injury. The link should slide into place without forcing, and make sure both pins are fully seated and properly secured. After installation, check chain alignment and test operation before putting the system back under full load. Keep a spare on hand since chain repairs always seem to happen at the worst possible moment.
