Detailed
About A620 Agricultural Chain
The CTS A620 agricultural chain is the heaviest A-type steel roller chain in our agricultural range, with a 42.01 mm pitch and a wide 24.51 mm inner width for high-capacity conveying. Built from heat-treated 45Mn steel with shot-peened, pre-lubricated components, the A620 handles heavy loads, impact, and abrasive conditions in threshing platforms, bulk conveyors, and large harvesting equipment.
The A620 is directly interchangeable with other major A-type agricultural chain brands, and is available in standard boxes, bulk coils or cut to length with connecting and offset links.
If you need any help, please contact us; CTS® is here to support you every step of the way.

A620 VS CA620 Agricultural Roller Chain
Both the A620 (A-type) and CA620 (CA-type) are 42.01 mm pitch steel agricultural roller chains with identical core dimensions and the same 39.1 kN (8886 lbf) tensile strength — so they fit the same sprockets and are interchangeable in most applications. The real difference is build grade, plate design, and the job each one was optimized for.
| Feature | A620 Roller Chain (A-type) | |

When to Choose the A620
✔ General power transmission and conveying on combine harvesters, balers, forage harvesters, and manure spreaders
✔ Hay elevator and grain handling systems
✔ When you need a proven, economical standard-duty chain that is fully OEM-interchangeable
✔ When weight matters, A620 chain is lighter than CA620 chain.
When to Choose the CA620
✔ Corn head gathering chains and other high-shock, high-wear header applications
✔ Direct replacement for John Deere, Case IH, New Holland and other major-brand gathering chains
✔ Planters, grain elevators and heavy conveyors where maximum wear and shock resistance matter
✔ When attachments are required (A1, K1, F2 or custom per drawing)
