About #40H Heavy Duty Roller Chains

CTS® #40H Roller Chain

CTS ANSI #40H heavy-duty roller chain is a 12.7mm (1/2-inch) pitch chain built to ANSI B29.1, with thicker link plates and stronger pins than standard #40. Fully interchangeable with other ANSI-certified 40H chains and compatible with #40/#40H sprockets, it is designed for high-load and abrasive working conditions.

CTS® high-quality ANSI #40 heavy-duty roller chains built to keep your machine running!

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

#40H VS #40 Roller Chain

Feature	ANSI #40H Roller Chain	ANSI #40 Roller Chain
Pitch	12.70 mm	12.70mm
Plate Thickness	2.03 mm	1.50 mm

Both #40 and #40H chains have a pitch of 12.70 mm; the side plate thickness in #40H is greater. This added material provides the chain with enhanced resistance to fatigue and stretching, particularly under fluctuating or impact-heavy loads.

Additionally, heavy-duty chains generally weigh more per meter and may slightly increase inertia in high-speed systems. However, this trade-off is often acceptable in exchange for much greater durability and longer operational life.

Applications of ANSI #40H Heavy Duty Roller Chain

#40H heavy-duty roller chain enables them to handle 15% to 30% more working load and resist fatigue more effectively than standard #40 chains. So #40H chain works well in tough places like mining, forestry, and farm machines:

- High-load conveyors and elevators in mining and bulk material handling

- Agricultural machinery - combines, balers, and harvesting equipment

- Oil field and drilling equipment

- Heavy packaging and bottling machinery

- General industrial drives requiring higher fatigue resistance than standard #40
