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 denotes the specific style of the chain, typically indicating the use of hardened steel rollers and pins, which enhances strength, wear resistance, and overall durability.
• 1 at the end signifies that it is a Simplex chain, meaning it has one row of rollers. This makes the chain simpler and less expensive than duplex or triplex chains, while still providing adequate power transmission for medium-duty applications.

2. Simplex Chain:

• A Simplex chain has one row of rollers, offering several advantages:
  • Cost-Effective: The 12B-1 simplex chain is more affordable than duplex or triplex chains, as it features fewer components and a simpler design.
  • Moderate Load Capacity: It is designed to handle moderate loads, making it ideal for applications where the power transmission needs are not excessively high.
  • Simple Design: The single-row roller design makes it easier to maintain, install, and service.
  • Compact and Lightweight: The simplex design is typically lighter and more compact than duplex or triplex chains, making it suitable for applications with space or weight constraints.

3. Common Applications:

The 12B-1 Simplex roller chain is ideal for various medium-duty applications where reliable power transmission is needed, including:

• Conveyor Systems: Used in material handling systems, such as conveyors for light to moderate loads.
• Agricultural Equipment: Suitable for farm machinery like seeders, harvesters, and other types of equipment.
• Power Transmission: Found in machinery that requires dependable power transfer in light to medium-duty systems.
• General Industrial Machinery: Ideal for use in applications like food processing, packaging, and light manufacturing where moderate power transmission is needed.

4. Material and Construction:

• Steel Construction: The 12B-1 roller chain is made from high-quality steel, which provides durability and resistance to wear under typical operating conditions.
• Corrosion Resistance: Some versions may come with corrosion-resistant coatings (e.g., zinc plating or other protective coatings) to prevent rust in moist or corrosive environments.
• Heat Treatment: The chain’s pins and rollers are heat-treated to increase their hardness, strength, and wear resistance, improving the chain’s longevity and performance.
• Lubrication: Proper lubrication is essential for reducing friction, preventing wear, and ensuring smooth operation. It also helps in extending the service life of the chain.

5. Dimensions:

• The 12B-1 Simplex roller chain has the following key dimensions:
  • Pitch: 3/8 inch (9.525 mm), which is the standard distance between the centers of two adjacent pins.
  • Simplex Design: The chain features one row of rollers, making it a simpler and more cost-effective option compared to duplex or triplex chains.

6. Advantages of Simplex Chains:

• Cost-Effective: The 12B-1 simplex chain is more affordable than duplex or triplex chains, thanks to its simpler construction with fewer components.
• Moderate Load Capacity: It is suitable for applications where moderate load-bearing capacity is needed, such as light conveyors, agricultural machinery, and general industrial machinery.
• Easier to Maintain: With fewer components, the simplex chain is easier to install, maintain, and replace, which can reduce downtime and maintenance costs.
• Compact and Lightweight: The 12B-1 simplex chain’s compact design makes it ideal for systems with space or weight limitations.
