Description

NIS Roller Chain 28B-3 is a type of Triplex roller chain, typically used in heavy-duty applications like industrial machinery, conveyors, and motor-driven equipment. It features three rows of rollers, which makes it more durable and capable of handling higher loads compared to standard single or double-row roller chains.

Here’s a breakdown of the key components and features of the 28B-3 Triplex roller chain:

1. Chain Size and Classification:

• 28B refers to the size of the chain, where:
  • 28 is the pitch, which is 1 inch (or 25.4 mm) between the centers of two adjacent pins.
  • The B denotes a specific style of roller chain, and in this case, it usually indicates the use of standard, hardened steel rollers and pins.

2. Triplex Chain:

• Triplex means the chain has three rows of rollers. This provides:
  • Higher load capacity than a standard single or double-row chain.
  • Increased durability and strength, suitable for applications where high power transmission and long service life are required.

3. Common Uses:

• The 28B-3 triplex roller chain is often used in applications where increased strength and durability are needed, such as:
  • Agricultural machinery
  • Industrial conveyors
  • Power transmission systems
  • Heavy-duty vehicles
  • Automated systems

4. Material and Construction:

• Steel: Most triplex roller chains like the 28B-3 are made from high-strength steel. In some cases, they may have corrosion-resistant coatings, like zinc plating, for use in outdoor or corrosive environments.
• Heat Treatment: Typically, the components are heat-treated for enhanced durability and resistance to wear.
• Lubrication: Roller chains generally require proper lubrication to ensure smooth operation and to minimize wear over time.

5. Dimensions:

• The exact dimensions of the chain will vary slightly by manufacturer, but typical dimensions for a 28B-3 include a pitch of 1 inch (25.4 mm), with each link including a roller and pin arrangement suited for heavy loads.

6. Advantages of Triplex Chains:

• Higher Load Capacity: Compared to duplex or simplex chains, the triplex design offers better strength and durability for heavier-duty applications.
• Longer Service Life: These chains tend to last longer under harsh operating conditions, reducing maintenance and replacement costs.
