Rollers are widely used components with simple yet highly efficient and diverse properties that drive the development of processed materials, product manufacturing, and industrial production. While standard rollers are the actual contact material, they can be used to convey materials and transport finished products. Whatever the industrial application, a perfectly matched roller conveying system can be designed.
Depending on the material with which the roller is in contact with the material or product, the roller can fulfill different functions. Commonly used roller materials are plastic and metal. The different materials of the rollers ensure their resilience and service life, as well as determine their loading capacity. Today we take a closer look at the characteristics and uses of plastic rollers.
Typically these types of rollers are lighter, quieter, and more resistant to corrosion. They are often used in projects where a large contact area is required and friction is maintained. They are also used in more delicate operations, such as handling smooth-surfaced cartons and small materials. These types of rollers are used where the surface of the work piece or the entire part cannot be damaged. Similarly, rubber rollers are used in processing applications where lighter materials are required, such as paper, textile, or sheet metal fabrication or machining. These rollers can be used in conjunction with a variety of hardware such as bearings, set screws, bushings, bolts, key ways, or shafts.
Plastic rollers are cheaper to manufacture and more cost-effective. However, it is not necessarily the only reason why people use this particular material. Plastic rollers are not only cost-effective but also functional and suitable for wet or humid climates, as they are less prone to oxidation, and rust and are not conducive to microbial growth. Ideal for working environments where regular cleaning is required, this makes them the preferred choice for roller conveyors in the food industry. Commonly used in the light industry to carry small loads.
Polyurethane rollers are cylindrical rollers covered by a layer of elastomeric material called polyurethane. Depending on the application, the inner roller core is susceptible to scratches, dents, corrosion, and other types of damage. The polyurethane layer uses its inherent properties such as abrasion resistance and impact strength to protect the inner roller core. The most desirable properties of polyurethane are its toughness, high impact resistance, and shock absorption. It is commonly used in printing, material transport, etc., and can be used in both light and heavy industries.
Polyethylene is an ultra-high molecular weight material with a wide range of uses. It is very self-lubricating and does not stand sticky. It, therefore, does not adhere to material build-ups. This property also makes it much quieter in operation and optimizes the working environment. They are also resistant to wear and impact and have a long service life. It is seven times more resistant to wear than steel and three times more resistant than nylon. In addition, polypropylene has very good tensile durability as it means very good load-bearing capacity. It is commonly used in heavy industrial manufacturing.
Rubber is used to protect conveyor rollers made of various other materials. You will find rubber covers for rollers with thicknesses ranging from 2 mm to 20 mm thick. The rollers can be covered with rubber from end to end or just in the middle, or even in different parts. The additional rubber covering from the roller gives it good abrasion resistance, is less prone to deterioration, and increases its service life. Commonly used in the light industry.
Depending on the environment and material to be transported, we can customize the applicable plastic roller for you. Feel free to contact GCS professional roller conveyor manufacturers to start a new roller conveying project.
