WH vs WR Series – How to Choose?

Both WH and WR series belong to offset sidebar chains, but they are designed for slightly different applications:

WH Series (Heavy Duty Standard Choice)

• More commonly used in general heavy-duty conveyors
• Balanced strength and cost-performance
• Suitable for grain handling, feed mills, and bulk material transport
• Recommended for most standard applications

👉 If you are not sure, WH series is usually the safest and most economical choice

WR Series (Heavy Load / Reinforced Type)

• Thicker sidebars and stronger structure
• Designed for heavier loads and more demanding environments
• Better performance under continuous high stress
• Suitable for mining, cement, and harsh industrial conditions

👉 Choose WR series when:

  • Load is very high
  • Working condition is harsh
  • Service life requirement is critical

Offset Sidebar Chain vs Standard Roller Chain

Compared with standard roller chains, offset sidebar chains are specifically designed for heavy-duty and abrasive applications.

Higher Strength: Welded steel construction provides much higher load capacity than standard roller chains
Better Impact Resistance: Suitable for handling bulk materials with shock loads
Improved Durability: Performs well in dusty, dirty, and abrasive environments
Flexible Design: Offset sidebar structure allows better articulation under heavy loads
Lower Maintenance Frequency: Longer service life reduces downtime and replacement cost

Standard roller chains are typically used for lighter, cleaner environments, while offset sidebar chains are the preferred solution for heavy-duty conveying systems.

Customization Options

We can supply offset sidebar chains based on your requirements, including:

• Different pitches and dimensions
• Material options (carbon steel, alloy steel)
• Heat treatment for improved wear resistance
• Attachments and special configurations

FAQ – Offset Sidebar Chain

What is an offset sidebar chain?

An offset sidebar chain, also known as a welded steel cranked link chain, is a heavy-duty conveyor chain designed for bulk material handling systems. Its offset link structure improves flexibility and load distribution in demanding conveying environments.

What are offset sidebar chains used for?

Offset sidebar chains are commonly used in drag conveyors, grain handling systems, feed mills, mining operations, cement plants, and other bulk material transport applications requiring durable chain performance.

What are the main features of an offset sidebar chain?

Offset sidebar chains feature welded steel construction, high tensile strength, wear resistance, and improved articulation through the cranked link design. These characteristics make them suitable for abrasive and high-impact conveying conditions.

What chain series are available for offset sidebar chains?

Offset sidebar chains are commonly available in WH and WR series. Typical models include WH79, WH82, WH124, WH132, WH150, WH155, WH157, and WR124 for different conveyor requirements.

What is the difference between WH and WR series chains?

WH series chains are widely used for general heavy-duty conveying applications, offering balanced performance and cost efficiency. WR series chains are reinforced for heavier loads and more demanding working conditions.

What materials are used to manufacture offset sidebar chains?

Offset sidebar chains are typically manufactured from carbon steel or alloy steel. Heat treatment can also be applied to improve wear resistance, strength, and service life.

How do I choose the correct offset sidebar chain size?

Selecting the correct chain depends on conveyor load, pitch size, operating environment, sprocket compatibility, and conveying capacity. Matching the chain to the system requirements helps ensure reliable performance.

Can offset sidebar chains be customized?

Yes, offset sidebar chains can be customized in pitch, attachment design, material grade, heat treatment, and welded flight configuration to match specific conveyor system requirements.
