Double pitch chains, characterized by their longer link pitch, offer a cost-effective and efficient solution for various applications requiring low-speed and high-load transmission. 

These chains are designed to handle greater distances between sprocket teeth while maintaining strength and durability. 

This design reduces weight and cost, making them suitable for diverse industrial uses.

What is a Double Pitch Roller Chain?

A double pitch roller chain is a type of chain where the distance between roller centers (pitch) is twice that of a standard roller chain. 

This design allows for longer chain lengths with fewer components, reducing the overall weight and cost while maintaining the chain’s strength and durability. 

Double pitch roller chains are commonly used in applications that require low-speed power transmission and large center distances, such as in agricultural machinery and conveyor systems.

Double Pitch Chain Sizes

Double pitch chains come in various sizes, each suited for different applications and load requirements. Here are some common sizes:

Chain Size	Pitch (in)	Roller Diameter (in)	Width Between Inner Plates (in)	Pin Diameter (in)
C2040	1.000	0.312	0.312	0.156
C2050	1.250	0.400	0.375	0.200
C2060H	1.500	0.469	0.500	0.234
C2080H	2.000	0.625	0.625	0.312
C2100H	2.500	0.750	0.750	0.375
C2160H	3.000	0.938	1.000	0.500

These sizes cater to different needs, from lightweight applications to heavy-duty tasks requiring robust chains.

Double Pitch Attachment Chain

Double pitch attachment chains are specialized chains that include attachments for securing or guiding products during transportation. 

These attachments can be customized to meet specific operational requirements.

A1 Attachment

A1 attachment consists of a single bent link on one side of the chain, providing a simple solution for light-duty attachments.

A2 Attachment

A2 attachment includes bent links on both sides of the chain, offering balanced attachment points for stability and increased load capacity.

K1 Attachment

K1 attachment features a bent link with an extended pin on one side, which is ideal for applications that need a secure attachment point.

K2 Attachment

K2 attachment has bent links with extended pins on both sides of the chain, providing maximum stability and versatility for complex attachment needs.

Common Styles of Double Pitch Chains

Double pitch chains come in several styles, each designed to meet specific operational requirements.

Standard Style Double Pitch Roller Chain

The standard style double pitch roller chain is designed for general-purpose use, featuring standard rollers and extended pitch links. 

It is suitable for applications requiring low-speed power transmission and long-distance conveyance.

Oversized Roller Double Pitch Roller Chain

Oversized roller double pitch roller chains have larger rollers compared to the standard style, offering improved performance in applications involving heavy loads and rough surfaces. 

The larger rollers provide better contact with the sprocket teeth, reducing wear and extending the chain’s lifespan.

A-Style Double Pitch Roller Chain

A-style double pitch roller chains feature straight side plates, providing a simple and efficient solution for applications with minimal side load requirements. 

This style is commonly used in conveyors and light-duty power transmission systems.

Metric Double Pitch Roller Chain

Metric double pitch roller chains are designed according to metric specifications, making them compatible with machinery and equipment that follow international standards. 

These chains offer versatility and global applicability in various industries.

Hollow Pin Double Pitch Roller Chain

Hollow pin double pitch roller chains have hollow pins, allowing for easy attachment of crossrods, crossbars, and other components. 

This design is ideal for applications requiring frequent attachment modifications and customizations.

Corrosion Resistant Double Pitch Roller Chain

Corrosion-resistant double pitch roller chains are made from materials such as stainless steel or coated with corrosion-resistant finishes. 

These chains are suitable for applications in harsh environments, including food processing, chemical industries, and outdoor equipment.
