Description

1. Chain Size and Classification:

• 12B refers to the size of the chain:
  • 12 indicates the pitch, which is the distance between the centers of two adjacent pins. For the 12B chain, the pitch is 3/8 inch (or 9.525 mm).
  • B refers to the specific style of the chain, which typically uses hardened steel rollers and pins for greater wear resistance and strength.

2. Duplex Chain:

• Duplex means that the chain has two rows of rollers, providing multiple benefits over a Simplex chain:
  • Higher Load Capacity: The duplex design enables the chain to handle higher loads than a Simplex chain (which has a single row of rollers), making the 12B-2 ideal for medium-duty applications where increased strength is needed.
  • Improved Durability: The two rows of rollers distribute the load more evenly, reducing wear and extending the chain’s overall lifespan.

3. Common Applications:

• The 12B-2 Duplex roller chain is widely used in various industrial and mechanical applications, including:
  • Industrial Machinery: Suitable for use in conveyor systems, packaging lines, and production equipment, where reliable power transmission is essential.
  • Power Transmission Systems: Ideal for applications that require efficient power transfer under moderate loads.
  • Automated Systems: Used in machinery and systems that operate continuously and require consistent and smooth operation.
  • General Machinery: Commonly found in manufacturing, agriculture, and other industries requiring durable, medium-duty chain drives.

4. Material and Construction:

• Steel: The 12B-2 roller chain is typically made from high-quality steel, ensuring durability and resistance to wear over time.
• Corrosion Resistance: Certain variants may come with corrosion-resistant coatings (such as zinc plating), making them suitable for environments where moisture or corrosive elements are present.
• Heat Treatment: The pins and rollers of the chain are often heat-treated to enhance hardness and wear resistance, extending the life of the chain.
• Lubrication: Regular lubrication is crucial to reduce friction and wear, ensuring smooth and efficient operation while increasing the service life of the chain.

5. Dimensions:

• The 12B-2 Duplex roller chain features:
  • Pitch: 3/8 inch (9.525 mm), which is the distance between the centers of two adjacent pins.
  • Duplex Design: The chain has two rows of rollers, which offer increased load-bearing capacity and strength compared to simplex chains.

6. Advantages of Duplex Chains:

• Higher Load Capacity: The duplex design allows the 12B-2 chain to handle more load than a Simplex chain, making it suitable for moderate-duty applications that require increased strength.
• Improved Durability: By distributing the load across two rows of rollers, the duplex design reduces wear and enhances the chain’s durability over time.
• Reduced Maintenance: Duplex chains generally require less frequent maintenance than simplex chains due to their higher strength and durability, leading to fewer breakdowns and lower operational costs.
• Efficient Power Transmission: The 12B-2 duplex roller chain ensures smooth, reliable, and efficient power transmission, making it ideal for applications where continuous operation is necessary.
