Roller Chain for Forklifts

Roller Chains & Sprockets

Roller chains are widely used in forklifts to transmit power, and sprockets are essential components that drive the chain. The roller chain and sprockets should be selected according to the working conditions, load, speed, and other factors to ensure reliable transmission and long service life.

Roller Chain

Roller chains consist of a series of cylindrical rollers connected by side links. The rollers are free to rotate on the bushings, which are press-fit into the inner link plates. The outer link plates are press-fit onto the rollers and hold the chain together.

Sprocket

Sprockets are wheels with teeth that mesh with the rollers of the chain. The teeth are profiled to ensure smooth engagement and minimize wear. The sprockets should be made of high-quality materials and precisely machined to ensure accurate pitch diameter and alignment.

What is Industrial Roller Chain used for?

Industrial roller chain is used in many applications that require the transmission of motion and power, such as conveyors, packaging machines, printing presses, and of course forklifts. Its advantages include high efficiency, low noise, and long service life.

Conveyors

Roller chains are commonly used in conveyor systems because they can handle heavy loads and operate at high speeds. The chains can be single-strand or multi-strand, and the sprockets can have different numbers of teeth to control the speed ratio.

Packaging Machines

Packaging machines use roller chains to drive the moving parts, such as the filling stations, sealing stations, and labeling stations. The chains must be precise in length and pitch to ensure accurate timing and synchronization of the different operations.

Printing Presses

Printing presses use roller chains to drive the printing cylinders and ink rollers. The chains must be able to withstand the high tension and shock loads generated by the sudden starts and stops of the press.

TYPES OF ROLLER CHAINS

There are many types of roller chains available, each designed for specific applications. Some of the most common types are:

Standard Roller Chain

The standard roller chain is the most widely used type, with a simple design and low cost. It is suitable for applications with moderate loads and speeds, such as forklifts.

Heavy-Duty Roller Chain

The heavy-duty roller chain has larger rollers and pins to increase the fatigue strength and wear resistance. It is suitable for applications with high loads and speeds, such as mining equipment.

Double-Pitch Roller Chain

The double-pitch roller chain has twice the pitch of the standard chain, which allows for a larger sprocket to be used. It is suitable for applications that require a longer center distance, such as conveyors.

Attachment Roller Chain

The attachment roller chain has extended pins or plates that can carry attachments, such as hooks, buckets, or flights. It is suitable for applications that require material handling, such as elevators or escalators.

Stainless Steel Roller Chain

The stainless steel roller chain is made of corrosion-resistant materials, such as AISI 304 or 316 stainless steel. It is suitable for applications that require cleanliness and hygiene, such as food processing or pharmaceuticals.

How to Choose or Customize Roller Chains

When selecting or customizing roller chains for forklifts, the following parameters and conditions should be considered:

Load Capacity

The load capacity of the roller chain depends on the tensile strength of the chain and the allowable stress of the material. The load capacity should be greater than the maximum load that the forklift can handle.

Speed Range

The speed range of the roller chain depends on the pitch, roller diameter, and accuracy of the chain and sprocket. The speed range should be within the operating range of the forklift.

Working Environment

The working environment of the roller chain includes temperature, humidity, dust, and corrosive substances. The roller chain should be made of materials that can withstand the environment or be protected by coatings or seals.

Maintenance

The maintenance of the roller chain includes lubrication, tension adjustment, and inspection. The roller chain should be designed for easy maintenance and have a long service life.

Customization

The customization of the roller chain includes special lengths, attachments, coatings, and materials. The roller chain can be customized to meet specific requirements and improve performance.
