Description

1. Chain Size and Classification:

  • 28B refers to the size of the chain:
    • 28 indicates the pitch, which is the distance between the centers of two adjacent pins. For the 28B chain, the pitch is typically 7/8 inch (or 22.23 mm).
    • B designates a specific style of chain that is usually equipped with hardened steel rollers and pins, offering superior wear resistance and strength.

2. Duplex Chain:

  • Duplex means that the chain has two rows of rollers, which provides several key benefits:
    • Higher Load Capacity: The duplex design enables the chain to handle more load than a Simplex chain (which has only one row of rollers). This makes the 28B-2 chain suitable for medium-to-heavy-duty applications.
    • Improved Durability: The additional row of rollers distributes the load more evenly, which reduces wear and tear, leading to a longer service life, especially in high-stress environments.

3. Common Applications:

  • The 28B-2 Duplex roller chain is typically used in a wide range of industrial and mechanical applications that require high strength, reliability, and durability:
    • Industrial machinery: In applications such as conveyor systems, assembly lines, and other heavy-duty equipment.
    • Power transmission systems: For systems that need to handle higher loads and offer dependable performance over time.
    • Automated systems: In machines and mechanical systems requiring consistent and efficient power transmission.
    • Heavy-duty equipment: In industries such as construction, agriculture, mining, and manufacturing, where equipment operates under substantial stress.

4. Material and Construction:

  • Steel: The 28B-2 roller chain is typically made from high-strength steel, ensuring durability and resistance to wear.
  • Corrosion Resistance: Certain versions of the chain may feature corrosion-resistant coatings such as zinc plating, making it suitable for outdoor and corrosive environments.
  • Heat Treatment: The components of the chain, such as rollers and pins, are often heat-treated to improve their hardness and resistance to wear.
  • Lubrication: Proper lubrication is essential to ensure smooth operation, minimize friction, and extend the chain’s service life.

5. Dimensions:

  • The 28B-2 Duplex roller chain typically features:
    • Pitch: 7/8 inch (22.23 mm), which is the standard distance between the centers of adjacent pins.
    • Duplex design: The chain has two rows of rollers, allowing it to carry heavier loads compared to Simplex chains.

6. Advantages of Duplex Chains:

  • Higher Load Capacity: The duplex design allows for more efficient handling of higher loads compared to simplex chains. The 28B-2 chain is well-suited for applications that demand more strength.
  • Increased Durability: The two rows of rollers help distribute the load more evenly, reducing wear and improving the overall durability of the chain.
  • Reduced Maintenance: Because duplex chains are stronger and more durable, they generally require less maintenance than simplex chains, reducing downtime and costs.
  • Efficient Power Transmission: The duplex chain provides reliable and efficient power transmission, even in high-load applications, ensuring smooth and consistent operation.
