What are The Types of Double Pitch Chain?







Double Pitch Chains are a type of conveyor chain with extended pitch (twice the pitch of a standard roller chain) used in light to medium load conveyor applications. These chains come in different types based on their design, construction, and intended use. Here’s a breakdown of the most common types of Double Pitch Chains:

1. Standard Roller Type Double Pitch Chain (A-Type):

• Design: These chains feature small, standard-sized rollers similar to those found in standard roller chains.

• Application: Primarily used in light to medium-load conveying applications where low friction and wear resistance are essential. It works well for transmission drives as well.

• Key Feature: The rollers have a smaller diameter, making them suitable for smooth movement along flat surfaces or guide rails.

• Example Use: Automated conveyors in packaging or assembly lines.

2. Large Roller Type Double Pitch Chain (C-Type):

• Design: These chains have larger rollers compared to the standard type, allowing them to roll over surfaces more easily.

• Application: Commonly used in conveyor systems where the chain rolls directly on the conveyor tracks or surfaces. Large rollers reduce friction and wear on the conveyor bed.

• Key Feature: The large roller design reduces wear on both the chain and the conveyor bed, leading to smoother, more efficient operation.

• Example Use: Material handling conveyors, especially for heavy loads.

3. Double Pitch Conveyor Chain with Attachments:

• Design: These chains can be fitted with different types of attachments (such as brackets, lugs, or slats) to suit specific conveying needs.

• Application: Used in applications where the chain must carry or push products along the conveyor. Attachments help customize the chain for specific items or transport requirements.

• Key Feature: The ability to customize the chain with different attachments for specialized tasks.

• Example Use: Assembly lines, packaging industries, or food processing where products must be moved, sorted, or elevated.

4. Hollow Pin Type Double Pitch Chain:

• Design: This type has hollow pins, allowing for the easy attachment of cross rods or other custom attachments without disassembling the chain.

• Application: Commonly used in applications requiring flexible configurations or custom attachments like slats or flights.

• Key Feature: Hollow pins make the chain more versatile by allowing attachments to be added or removed without disconnecting the chain.

• Example Use: Conveyor systems that transport bulk materials like grains or small parts.

5. Double Pitch Leaf Chain:

• Design: This type is composed of link plates and pins, but it does not have rollers. It is designed for high-tension applications.

• Application: Mainly used in tension-loaded applications like forklifts or elevators where the chain must withstand heavy lifting and pulling forces.

• Key Feature: High strength for tension applications but less suitable for direct rolling or sliding applications.

• Example Use: Forklift mast chains or elevator lifting chains.

6. Double Pitch Corrosion-Resistant Chain:

• Design: Manufactured with stainless steel or other corrosion-resistant materials to withstand harsh environments.

• Application: Suitable for industries where the chain is exposed to moisture, chemicals, or extreme temperatures.

• Key Feature: Resistance to rust, corrosion, and wear, making them ideal for outdoor or sanitary environments.

• Example Use: Food processing, pharmaceutical industries, or outdoor conveyors.

7. Heavy-Duty Double Pitch Chain:

• Design: Made for more robust applications, these chains have thicker plates and stronger pins for handling heavy loads.

• Application: Used in industries where large, heavy items must be conveyed or where high strength is required.

• Key Feature: Greater strength and durability than standard double pitch chains.

• Example Use: Bulk material handling, construction equipment, or mining operations.

Summary of Key Types of Double Pitch Chain:

Each type of Double Pitch Chain serves specific needs, from general conveyor applications to heavy-duty and corrosion-resistant environments.
