The roller for conveyor that powers your conveyor belt system plays an integral role in the efficiency of the entire system. A conveyor roller, or roller, ensures that your conveyor belt moves smoothly and consistently, making sure that whatever you’re transporting stays safe, secure, and in place throughout the journey. It’s important to choose the right drum line, however, so that you not only get durability but also power with smooth movement and constant speed. To find out how to select the right roller for your conveyor belt system, keep reading!

Key points of roller conveyor selection

When it comes to choosing a roller, conveyor belt components are very different from a common ball bearing. The right roller line and material are important because they can reduce maintenance costs, improve bearing life and help you maximize your efficiency. Some of these components include: line tooth number, side flange type, backup plate type and high temperature protective plate; to name a few.

These elements will determine how well your rollers perform over time and what kind of maintenance is required to keep them running smoothly. It’s also important to consider other factors such as belt speed, load capacity and belt tension when selecting a new set of rollers. Choosing the right conveyor belt components is essential in maintaining efficient production processes with minimal downtime.

Here’s key points of roller conveyor selection:

1. Starting with the first load, select drums made of different materials and types.

2. Since the top surface of a general conveyor roller is slightly lower than the side height of the fuselage, choose an appropriate height.

3. Knowing the items you sell, you should check the requirements of roller conveyor belt materials like material name, material properties, packaging size, machine material, rough size, and throughput requirements.

Once you present the conveyor belt components and requirements, you can take a look at different conveyor roller and belts.

How to select the wall thickness and shaft diameter of the roller?

Figuring out the wall thickness of the roller line and shaft diameter can be challenging. You must carry out mathematical calculations, even-out the weight of the conveyor material, account for the carrying capacity of each drum, and then make a decision about the wall thickness and shaft diameter.

The roller shaft diameter should not be less than six times greater than drum line thickness and not more than six times less than wall thickness. The shaft diameter should also not exceed half of roller line thickness. For example, if you have a 10-mm thick wall, then you must use at least a 150-mm roller shaft or no more than 60-mm wide shaft in order to fit properly. If however your material has an extremely high tensile strength and has very good frictional properties, it is possible to have an even larger ratio of line thickness to roller shaft diameter (even though these materials are rare). Also keep in mind that using a smaller or larger size will cause friction which will increase operating temperature and wear out your belt quickly.

How to select the material for the roller?

Larger-diameter rollers are often made of steel, whereas smaller-diameter rollers are usually constructed of aluminum or plastic. Conveyor rollers that transport heavy loads tend to have a heavier roller core than those that handle lighter loads.

Generally speaking, larger diameter rollers can be built from materials with high-strength properties, such as steel and stainless steel. It’s important to note that even if you are using a highly durable material such as these for your conveyor roller, regular inspections and maintenance should still be carried out on it at regular intervals so you can identify problems early and fix them before they become too costly.

The roller is an important part of any conveyor system, especially when it comes to transporting heavier loads. A good design can make a big difference in your company’s productivity and efficiency, so choosing a durable material is essential. When selecting a material, keep in mind that not all high-strength options are suitable for every application; each type has its pros and cons that you’ll need to consider carefully before making your choice.

Galvanized Carbon Steel (GCS)

GCS steel is coated with zinc to protect against corrosion. Sheetrock is most often used for external surfaces like fences and railings, or for some interior plumbing.


  • Rust protection
  • Easily inspected
  • Lower price


  • Can contaminate water
  • Internal corrosion

Stainless steel

Stainless steel is a kind of alloy which consists of various materials such as iron, chromium, nickel, and many others. Because of this, it possesses a variety of properties which make it well-suited for a lot of different industries, such as construction and jewelry-making.


  • Resistant to oxidation
  • Lasts for many years as it does not rust easily
  • Has a very high melting point



  • Costly
  • Displays dirt easily
  • Difficult to weld


Made of durable plastic and featuring stainless steel bearings and spindles, plastic rollers are ideal for humid or wash-down environments. They are most commonly used for lightweight transportation of goods.


  • Low cost
  • Durable
  • Water resistant
  • Uses less energy


  • Can produce toxic fumes
  • Can break under heavy load
  • Can get worn and torn faster than steel

How to select the length of the roller

The length of your roller for conveyor will depend on its specific use and the width of the goods to be transported. For example, a short belt will work best in an assembly line because operators need easy access to both sides of it. A longer belt will be better suited to moving material around in a warehouse or facility. When selecting your conveyor roller length, keep in mind that most rolls are about 6 feet long. When purchasing one for a specific application, take into account how many feet you’ll need and whether it needs to be cut down from a standard roll. You can always contact us with questions or measurements if you aren’t sure what length is right for you!

The first step in selecting a conveyor roller is determining what type of material will be moving over it. Each material has different characteristics and presents unique challenges, so knowing what you’re working with is important. In addition to weight and size, you’ll want to take into account temperature range, durability, abrasion resistance and moisture exposure. Once you know what your roller will be used for, you can decide which of our conveyor rollers best suit your needs.
