Endless belts are continuous belts used in conveying. They are called “endless” because they do not have seams or joints. To install them, operators stretch them over their conveying pulleys tightly enough to achieve and maintain contact with the pulleys. Friction helps maintain that contact.
Endless belts are used in a wide variety of power transmission and conveyor belt applications, including those in: agriculture, chemical, clean room, commercial food production, construction, manufacturing, metallurgy and mining.
When designing your endless belt drive system, belt manufacturers will consider a number of factors, including: the type of material or products you plan to convey, the weight of the items you plan to convey, the frequency with which you will use your system, the sanitation requirements of your belt conveyor (FDA, food-grade, etc.), the length of your system any of systems with which it must integrate.
Per your application requirements, they can choose belt materials and more. Endless belts are typically made from rubber elastomers, such as urethane, neoprene or nitrile rubber. Materials used to make endless belts must usually possess qualities including: elasticity, abrasion resistance, chemical resistance and durability. Manufacturers offer them in a variety of thicknesses, widths, lengths and load bearing capacities. They can create belts with a number of different textures, including: smooth, notched, ribbed and cogged.
Endless belts offer their users a number of advantages. First, without seams, they are stronger, less prone to wear and less prone to bacteria growth. In addition, they run smoothly, with low vibration and with low stress. All in all, they wear down less quickly and last longer than other types of belts. Because endless belts are made from elastomeric material, they are stretchy and can be tensioned without extra equipment. Another advantage of endless belts is the fact that they are extremely reliable, so you can count on them during your high volume runs.
