❖ How does the conveyor roller bear the load?

That is the load that a roller can bear? It's correct. But there are still confusions in roller selection. Novices often make the mistake of understanding the concept behind conveyor roller loading. Many times, the load capacity is estimated to be lower when considering the thickness of the roller.

Is the bearing capacity of the roller important?

Among all, the load capacity of conveyor rollers is very important. What's so special about that? One must understand that the load capacity of the roller is distributed and not concentric.

If you have to carry a 1 ton pallet, it doesn't mean that the load capacity of each roller has to be 1 ton. If the size of the pallet is 1mtr x 1mtr, the load is on an area of 1m2. The rollers will have an area of 1 SqM, will have a load capacity of 1 ton. This load does not rest on a single roller. If there are 10 rollers in this area, 1 ton load, will be divided over 10 rollers.

Meaning if a roller with a length of 500mm is provided with a load capacity of 50Kg, it implies that you can put a load of 500mm at the same time. If you put a mass of 50kg on any small part of the roller, say 100mm, it is not allowed, it concentrically loads.

How to calculate the load capacity of conveyor rollers?

The load capacity of the conveyor roller is decisive for the conveyor system. The system being designed can cause you problems that damage the system. Designing too many conveyor systems can go over budget.

Calculating loads on conveyor rollers is simple and very easy arithmetic. Assume that you have to design a Gravity Roller Conveyor System to transport carton boxes. The weight of the carton box is 50kg The length of the box is 400mm The width of the box is 300mm

Lets calculate the width of the rollers = width of the carton box + 50mm So the length of the roller is 350mm. Now we have to decide how many rollers are under the carton?

For one component, the Box, the product must stabilize 3 rollers below it, assuming the weight in the product is equally distributed. So 400/3 = 133mm will be the rolling step.
We will consider the 100mm roller pitch as a safer aspect. So there will be 4 rollers under the box at any time. It means 50kg weight will be distributed on 4 rollers. Calculating further, we will get 12.5kg. In the end we need 12.5kg of load-bearing rollers over a length of 350mm.

In addition, the load capacity depends on many other factors such as the concentricity of the product weight, the impact load generated on the roller when loading the component on the conveyor.

❖ What to pay attention to when replacing conveyor rollers?

❖ How to choose the most standard conveyor roller?

To achieve the highest efficiency, pay attention to how to choose the most standard conveyor roller. See a few factors below to know how to choose the correct conveyor roller:

- Type of conveyor belt:

The first step in choosing the best conveyor rollers for your application is to choose based on your loading material. For example, if your load material includes a sturdy, flat bottom, you need a conveyor with gravity rollers.

- Roller material:

Aluminum, Steel, or both? Next, decide what type of roller material will be best for your application. Industrial rollers are usually made of aluminum or steel. Here's a guide to choosing the type you need:

+ Aluminum roller: Choose aluminum roller for lighter, easier, faster installation.
+ Steel Rollers: Choose steel rollers when your application requires more durability.
+ Both: Choose both if you want lighter aluminum rollers with durable steel heads using a unique combination of inertial friction. This also reduces costs by using less raw materials and using more expensive materials only in areas where they are needed.
+ Or you can learn more about Plastic conveyor rollers, Stainless steel conveyor rollers, rubber conveyor rollers by following the link.

- Dimensions of conveyor roller:

Now you need to know what size rollers to choose from. You can determine the size you need by looking at the loading conditions. If your application has heavy loads, choose larger rollers that meet the overload per roller. As a general rule, ensure that at least 3 rollers are in contact with your load at all times. To ensure this, you may need to reduce the distance between the rollers.

- Set the roller high or low:

Depending on your application, you may need your conveyor rollers set high or low. What is the difference?:

High Rollers: Install rollers above the conveyor frame to allow for excessive loading.
Low Roller: Install the roller below the conveyor frame to allow the frame to act as a guard. For low installations, 1 point clearance is required on each side of the largest sized load to avoid conveyor failure.
