Roller Chain


What Is A Roller Chain?

A roller chain is a type of mechanical chain that is widely used in power transmission applications. It consists of a series of cylindrical rollers that are connected by links, which are then wrapped around sprockets to transmit torque and rotational speed between two shafts.

The basic construction of a roller chain includes inner links, outer links, pins, and rollers. The inner links and outer links are connected by pins, which allow the chain to articulate and wrap around sprockets. The rollers are positioned between the inner and outer links and rotate on the pins as the chain moves around the sprockets.

Roller chains are commonly used in industrial machinery, agriculture, automotive, and other applications where reliable and efficient power transmission is required. They are known for their high strength, durability, and efficiency, making them an ideal solution for a wide range of power transmission applications.


How To Maintain The Roller Chain?

Roller chains require regular maintenance to ensure that they operate properly. Here are some tips on how to maintain a roller chain:

Check the chain regularly. Look for signs of wear, such as stretched links, missing or damaged rollers, or bent pins
Lubricate the chain regularly. The type of lubricant you use depends on the environment in which the chain will operate
Keep your chain clean. Dirt and debris build up on the chain and sprockets, increasing wear
Adjust chain tension. Chains should be properly tensioned to prevent excessive wear and noise
Replace worn sprockets. Sprockets wear out over time

Roller Chain Advantage



Roller chains are made of strong materials, such as steel or stainless steel, that can withstand a lot of wear and tear.


Roller chains are a very efficient way to transmit power. They have a low coefficient of friction, which means that they lose very little energy as they move.


Roller chains are relatively quiet when they operate. This is important in some applications, such as conveyors, where noise can be a nuisance.

How an Roller Chain works?

A roller chain is a type of chain drive that is commonly used to transmit mechanical power. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. Roller chains are a simple, reliable, and efficient means of power transmission.

Here is how a roller chain works:

  1. The chain is driven by a sprocket. The sprocket has teeth that fit into the grooves of the chain.
  2. As the sprocket rotates, the chain moves along with it.
  3. The rollers in the chain roll along the teeth of the sprocket. This allows the chain to move smoothly and efficiently.
  4. The chain transmits the power from the sprocket to the load. The load can be anything that needs to be moved, such as a conveyor belt or a lifting mechanism.

Application of Roller Chain

Roller chains are a popular choice for conveyors because they are durable and can handle a lot of wear and tear. They are also relatively quiet, which is important in some applications.


Roller chains are used in machine tools to transmit power from the motor to the cutting tool. They are also used in indexing tables and other applications where precise movement is required.

Machine tools

Roller chains are used in lifting and hoisting equipment to transmit power from the motor to the load. They are also used in winches and other devices that require a high degree of strength and durability.

Lifting and hoisting equipment

Roller chains are used to transmit power from the pedals to the rear wheel in bicycles and motorcycles. They are also used in some cars and trucks.
