Identifying a pintle chain involves examining its unique design, characterized by open barrel construction and pivoting links. 

This chain type is distinct due to its robust and flexible nature, which allows for easy disassembly and reassembly. 

Pintle chains are typically used in agricultural, wastewater treatment, and industrial applications. 

Recognizing their specific sizes, links, and materials helps ensure proper use and maintenance.

What is a Pintle Chain?

A pintle chain is a type of industrial chain known for its open barrel design and pivoting links, which provide flexibility and ease of maintenance. 

These chains are commonly used in environments where materials need to be moved or processed, such as in agriculture, wastewater treatment, and other heavy-duty applications. 

The open barrel construction allows debris to pass through, reducing the risk of clogging and facilitating smoother operation.

Common Pintle Chain Sizes

The table below lists some of the common pintle chain sizes:

Chain Size	Pitch (in)	Width (in)	Pin Diameter (in)
400	1.631	1.062	0.312
600	2.250	1.500	0.437
800	2.609	1.875	0.500
1000	3.075	2.125	0.625
1200	3.750	2.437	0.750

Pintle Chain Classes

Class	Pitch (in)	Width (in)	Pin Diameter (in)	Typical Applications	Characteristics
400	1.631	1.062	0.312	Agriculture, conveyors, manure spreaders	Medium strength, flexible, open barrel design
600	2.250	1.500	0.437	Industrial conveyors, wastewater treatment	Higher strength, good for heavy loads, easy to clean
700	2.609	1.875	0.500	Heavy-duty agricultural and industrial use	Durable, capable of handling heavier loads than Class 600
800	2.609	1.875	0.500	Heavy-duty industrial applications	Robust construction, suitable for harsh environments
900	3.075	2.125	0.562	Heavy industrial use, mining, conveyors	High strength, durable, capable of handling very heavy loads
1000	3.075	2.125	0.625	Mining, large-scale conveyors, heavy machinery	Very high strength, designed for heavy and abrasive loads
1200	3.750	2.437	0.750	Extreme heavy-duty applications	Maximum strength, corrosion resistant, for extreme conditions

Pintle Chain Links and Accessories

Connecting Links

Connecting links are used to join two ends of a pintle chain. 

They are essential for assembling and disassembling the chain without needing special tools, making maintenance straightforward and efficient.

Offset Links

Offset links, also known as half links, are used to adjust the length of a pintle chain by a half-pitch increment. 

This adjustment capability is critical for achieving the correct chain length in various applications.

Attachment Links

Attachment links are specialized links that allow for the attachment of other components, such as slats or flights, to the pintle chain. 

These links are crucial for applications where the chain must carry or move materials.

Common Materials Used for Manufacturing Pintle Chains

Stainless Steel

Stainless steel is widely used for manufacturing pintle chains due to its corrosion resistance and durability. 

It is ideal for applications in harsh environments, such as wastewater treatment plants and food processing facilities. 

The main advantage of stainless steel pintle chains is their longevity and resistance to rust. 

However, they can be more expensive than other materials.

Cast Iron

Cast iron is another material used for pintle chains, known for its strength and durability. 

Cast iron pintle chains are suitable for heavy-duty applications, such as in agricultural equipment. 

While cast iron chains are robust and cost-effective, they are susceptible to rust if not properly maintained.

Plastic

Plastic pintle chains are used in applications where corrosion resistance and light weight are essential. 

These chains are often found in the food and beverage industry. 

The primary advantage of plastic pintle chains is their resistance to chemicals and moisture. 

However, they are not as strong as metal chains and may wear out faster under heavy loads.
