Steel cord belts are commonly used on machinery where there is any slippage in the drive system, for example to conveyor input or within a pump. Steel cord belts consist of an endless band of high-tenacity steel fabric with synthetic rubber cord where both edges should not be touching. Unlike V-belts, which can start slipping under tension, steel cords can increase travel distance without slippage.


A steel cord belt joint is a splice or connection device used to connect two ends of a steel cord conveyor belt. There are three main types of steel cord belt joints: mechanical, vulcanized, and splicing. Each type has its own advantages and disadvantages that should be considered when selecting the right type of joint for your application.

Types of Steel Cord Belt Joints

There are three types of steel cord belt joints: splicing, mechanical, and vulcanized. 

1. Splicing is the most common type of joint used for steel cord belts. It involves joining the two ends of the belt together by overlapping them and then stitching or welding them in place. Splicing is a strong and reliable method of joining belts, but it does require some specialized equipment and training to do properly. 

2. Mechanical joints are less common than splicing, but they offer some advantages over traditional splicing methods. Mechanical joints are made by connecting the two ends of the belt together with a series of metal clips or fasteners. This type of joint is quicker and easier to make than a spliced joint, but it is not as strong or reliable. 

3. Vulcanized joints are the strongest and most reliable type of steel cord belt joint, but they are also the most expensive and difficult to make. Vulcanized joints are made by bonding the two ends of the belt together with heat and pressure. This type of joint is virtually indestructible, but it requires special equipment and training to do properly.

Steel Cord Belt Advantages

The use of steel cord belts for tires has many advantages over other types of belts. Steel cord belt joints are much stronger than those made with other materials, and they last longer too. They’re also better able to resist impact and heat, making them ideal for high-performance tires. 

Another advantage of steel cord belts is that they’re much less likely to puncture than other types of belts. This is because steel cords are much thicker and more resistant to puncturing than other materials. Steel cord belts also don’t tend to stretch as much as other types of belts, so they provide better traction and handling.

How does it work?

A steel cord belt joint is used to connect two steel cord belts together. Steel cord belts are used in a variety of applications, such as conveying systems, material handling systems, and power transmission systems. Belt joints are necessary in order to create a continuous belt system. There are a variety of different types of belt joints, but the most common type is the steel cord belt joint.

Steel Cord Belt Disadvantages

There are several disadvantages of steel cord belt joints, which include:

1. They can be difficult to install, as the cords need to be aligned correctly.

2. They are not as flexible as other types of belt joints, so they can be less forgiving if installed incorrectly.

3. Steel cord belt joints can be noisy, due to the metal-on-metal contact. This can be an issue in applications where quiet operation is desired.

4. They tend to have a shorter lifespan than other types of belt joints, due to the increased wear and tear from the metal-on-metal contact.


A steel cord belt joint is a key component in ensuring the success of a conveyor belt installation. When correctly designed and installed, it will provide a strong, reliable, and effective means of joining two steel cord belts together. There are various types of steel cord belt joints available on the market, each with its own advantages and disadvantages. It is important to select the most appropriate type of joint for the specific application, taking into account factors such as the size and type of material to be conveyed, the operating environment, and the required belt life.
