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 1 3/4 inches (or 44.45 mm).
  • B refers to a specific style of the chain, typically meaning the chain uses hardened steel rollers and pins to enhance its strength, wear resistance, and durability.
• 1 at the end indicates that it is a Simplex chain, meaning it has a single row of rollers, which makes it simpler and more cost-effective than duplex or triplex chains.

2. Simplex Chain:

• Simplex refers to a chain with one row of rollers. This design has several key characteristics:
  • Cost-Effective: Simplex chains are generally more affordable due to their simpler construction, making them an excellent choice for applications with budget constraints.
  • Moderate Load Capacity: A simplex chain can handle moderate loads, but its load-bearing capacity is lower than that of duplex or triplex chains.
  • Simpler Design: With fewer components (one row of rollers), simplex chains are easier to install, maintain, and service.
  • Smaller and Lighter: The single-row design makes simplex chains lighter and more compact, which is advantageous in space-constrained applications.

3. Common Applications:

• The 28B-1 Simplex roller chain is typically used in medium-duty industrial applications that require moderate strength and load-bearing capacity:
  • Conveyor Systems: Ideal for use in material handling systems, packaging lines, and light-duty conveyors.
  • Power Transmission Systems: Suitable for medium-duty power transmission, including light machinery and industrial equipment.
  • Agricultural Equipment: Used in farm machinery such as seeders, harvesters, and other equipment requiring reliable chain-driven motion.
  • General Machinery: Can be found in a wide range of applications across industries such as food processing, light manufacturing, and automation, where moderate strength and reliability are necessary.

4. Material and Construction:

• Steel: The 28B-1 roller chain is made from high-quality steel, which ensures durability and resistance to wear and fatigue.
• Corrosion Resistance: Some versions of the chain may come with corrosion-resistant coatings (such as zinc plating) to provide protection in moist or corrosive environments.
• Heat Treatment: The rollers and pins are heat-treated to increase their hardness, wear resistance, and strength, ensuring long-term performance and reliability.
• Lubrication: Proper lubrication is essential to reduce friction, minimize wear, and ensure smooth operation. Regular lubrication extends the service life of the chain.

5. Dimensions:

• The 28B-1 Simplex roller chain has the following key dimensions:
  • Pitch: 1 3/4 inches (44.45 mm), which is the distance between the centers of two adjacent pins.
  • Simplex Design: The chain features one row of rollers, which provides a simpler construction but a lower load capacity compared to duplex or triplex chains.

6. Advantages of Simplex Chains:

• Cost-Effective: The 28B-1 simplex chain is generally more affordable than duplex or triplex chains because of its simpler design and fewer components.
• Moderate Load Capacity: Suitable for applications that require moderate load-bearing capacity, such as light to medium-duty industrial machinery and conveyors.
• Ease of Maintenance: With its simpler construction, the simplex chain is easier to maintain and service, leading to less downtime and lower maintenance costs.
• Reliable Power Transmission: The 28B-1 simplex roller chain provides smooth and consistent power transmission, ensuring reliable performance in moderate load applications.
