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.

Quality Assurance:

ISO9001: 2015 and GB/T24001-2016 / ISO14001: 2015.

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)	CA620 Roller Chain (CA-type)
Chain pitch	42.01 mm	42.01 mm
Roller diameter	17.91 mm	17.91 mm
Plate thickness	3.25 mm	3.25 mm

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)
