How Do Roller Chains Work?

Roller chains function as mechanical connectors, transferring power and motion between rotating components with precision. 

Built from a series of interlocking links, they fit snugly onto sprockets, enabling synchronized rotation of shafts and wheels in industrial systems.

There are various types of chains designed for specific uses:

• Single-strand chains: ideal for light-duty, low-speed applications.
  

• Double and triple-strand chains: made for higher loads and power-intensive systems.
  

• Specialty chains, such as hollow pin or nickel-plated versions, are tailored for technical requirements like corrosion resistance or easy customization.
  

Proper installation is key to performance. Chains must be well-aligned with sprockets and tensioned correctly to avoid premature wear. Regular lubrication minimizes friction and extends the lifespan of the chain. 

Routine inspections help detect slack, deformation, or damaged links that could impact machinery function.

Common Types of Roller Chains

Roller chains come in various types to suit a wide range of mechanical and industrial demands. From light-duty machinery to heavy-load systems, each variation is designed to meet specific performance requirements.

Some of the most common types include:

• Single-strand chains, used in general power transmission applications.
  

• Multi-strand chains, such as double or triple strand versions, which provide increased strength and load capacity.
  

• Coated chains, including stainless steel or nickel-plated options, ideal for corrosive or outdoor environments.
  

• Specialty chains, like hollow pin versions, often used in customizable conveyor systems.
  

Each type offers distinct benefits in terms of strength, flexibility, and durability. Choosing the right chain depends on your system’s specific operational conditions.

Roller Chains Applications

Roller chains are vital components in mechanical systems that require continuous motion, strength, and precision. Because of their reliability, they’re widely used across different industries and are key to keeping operations running smoothly.

Here are the main sectors where roller chains are commonly applied:

• Automotive and Transportation Industry
  Used in drive systems, engines, and lifting mechanisms, roller chains provide efficiency and long-lasting performance under high usage demands.
  

• Agriculture and Construction Equipment
  Heavy-duty machinery like tractors, harvesters, and excavators rely on chains built to endure dirt, moisture, and extreme working conditions.
  

• Industrial and Manufacturing Sector
  From assembly lines to conveyors and automated systems, roller chains ensure consistent operation and help maintain production flow.
  

• Custom and Specialty Applications
  Custom-built solutions, including specialized conveyor setups or corrosive environments, benefit from chains tailored to specific technical needs.

Explore Our Featured Roller Chain Categories

At PGN Bearings, we provide a full lineup of roller chains engineered for industrial, agricultural, and automotive applications. Below are our featured categories:

Carbon Steel Roller Chains

Designed for high performance and excellent cost-efficiency. A great example is the #40 Roller Chain x 100 feet, featuring a 0.5" pitch, an average tensile strength of 17.5 kN, and 10 free connecting links included.

Carbon steel roller chains typically undergo heat treatment — a crucial process that enhances their durability and overall performance. Techniques like carburizing, induction hardening, or case hardening contribute to:

• Improved hardness and wear resistance, minimizing friction between components;

• Increased tensile strength, allowing the chain to handle heavier loads;

• Better fatigue resistance, reducing the risk of cracks under cyclic stress;

• Balanced toughness and ductility, preventing brittle failure;

• Enhanced surface oxidation resistance, especially with methods like nitriding.

Even with these enhancements, proper lubrication or protective coatings are recommended to prevent corrosion in harsh environments.

Heavy Duty Roller Chains

Ideal for demanding loads and continuous operations. These chains feature reinforced side plates and are built for tough environments.

Double and Triple Strand Chains

Maximize power transmission in limited space. Available in Duplex and Triplex options for high-torque systems.

Stainless Steel Roller Chains

Corrosion-resistant and perfect for wet, chemical, or hygienic environments like food processing or pharmaceuticals.

Nickel Plated Roller Chains

Designed for weather-sensitive or mildly corrosive environments. The nickel coating extends lifespan and prevents rust.

Hollow Pin Roller Chains 

Support easy customization with integrated hollow pins for mounting accessories or attachments in conveyor systems.

Agricultural, Conveyor & Pintle Chains

Built for rugged environments—resist dust, mud, and uneven load conditions. Ideal for farming and conveyor operations.

Forklift Chains

Reliable performance for lifting systems. These chains withstand repeated tension cycles without compromising safety.

Motorcycle Chains

Engineered for durability, speed, and traction. Lightweight yet strong, they offer smooth power delivery for motorcycles.

Connecting Links and Offset Links

Critical for customizing chain length, making adjustments, or reconnecting broken segments safely and efficiently.

Tools

Notably the Roller Chain Cutter & Breaker Tool, compatible with multiple sizes. Designed to remove or adjust rivets cleanly during setup or maintenance.

Explore our categories and choose the chain that keeps your system running strong—with PGN Bearings quality built into every link.

How to Choose the Right Roller Chain for Your Application

Each setup comes with its own demands — whether it’s the type of load, working conditions, or space limitations.

For systems exposed to heavy loads or constant operation, reinforced models like heavy-duty or multi-strand chains are the best fit. If your equipment runs in humid or corrosive environments, stainless steel or nickel-plated chains offer the resistance needed to prevent premature wear.

When there’s limited space available, duplex and triplex chains provide higher power transmission without increasing the system’s footprint. 

And for setups that need customization or frequent adjustments, hollow pin chains offer flexibility, allowing easy integration of attachments and quick replacements.

In applications that demand precision — such as high-speed conveyors or synchronized automation systems — it's critical to use chains with minimal clearance and a smooth finish to ensure consistent motion.

Key points to guide your choice:

• Load type and usage frequency;

• Environmental conditions (humidity, temperature, chemicals);

• Space constraints within the equipment;

• Customization and maintenance needs;

• Precision and smooth motion requirements.
