Description

1. Chain Size and Classification:

  • 20B refers to the size of the chain:
    • 20 indicates the pitch, which is the distance between the centers of two adjacent pins. For the 20B chain, the pitch is 1/2 inch (or 12.7 mm).
    • B designates the specific style of the chain, which typically uses hardened steel rollers and pins for enhanced durability and wear resistance.

2. Duplex Chain:

  • Duplex means that the chain has two rows of rollers, which provides several advantages over simplex chains (which have a single row of rollers):
    • Higher Load Capacity: The duplex design enables the chain to carry more load than a Simplex chain. This makes the 20B-2 suitable for medium-duty applications where higher load-bearing capacity is required.
    • Improved Durability: The two rows of rollers distribute the load more evenly, reducing wear and improving the chain’s overall service life.

3. Common Applications:

  • The 20B-2 Duplex roller chain is ideal for a variety of industrial and mechanical applications:
    • Industrial Machinery: For systems such as conveyors, packaging lines, and production equipment where reliable power transmission is essential.
    • Power Transmission Systems: In applications that require smooth and efficient transmission of power under moderate loads.
    • Automated Systems: For machines that operate continuously and require strong, reliable chain drives.
    • General Machinery: Suitable for medium-duty equipment in manufacturing, agriculture, and other industries.

4. Material and Construction:

  • Steel: The 20B-2 roller chain is typically made from high-strength steel, ensuring durability and resistance to wear over time.
  • Corrosion Resistance: Some versions of the chain may be treated with corrosion-resistant coatings (e.g., zinc plating) to make it more suitable for use in outdoor or humid environments.
  • Heat Treatment: The pins and rollers of the chain are often heat-treated to improve hardness, wear resistance, and overall longevity.
  • Lubrication: Proper lubrication is essential for reducing friction and wear, ensuring smooth operation and extending the service life of the chain.

5. Dimensions:

  • The 20B-2 Duplex roller chain features:
    • Pitch: 1/2 inch (12.7 mm), which is the standard distance between the centers of adjacent pins.
    • Duplex Design: The chain has two rows of rollers, which allows it to handle greater loads compared to simplex chains, making it ideal for moderate-duty applications.

6. Advantages of Duplex Chains:

  • Higher Load Capacity: The duplex design allows the 20B-2 chain to support more load compared to a Simplex chain, which is beneficial in applications requiring more strength.
  • Improved Durability: With two rows of rollers, the load is distributed more evenly across the chain, reducing wear and improving the chain’s longevity.
  • Reduced Maintenance: Due to its increased strength and durability, duplex chains like the 20B-2 generally require less frequent maintenance compared to simplex chains.
  • Efficient Power Transmission: The 20B-2 duplex chain offers smooth and efficient power transmission, ensuring consistent performance in applications requiring continuous operation.
