Specifications of Rubber Conveyor Belt Types

Tensile Strength

Tensile strength refers to the maximum load a rubber conveyor belt can withstand before breaking. It is a critical specification that determines the belt’s ability to handle heavy loads. The tensile strength is usually measured in Newtons per millimeter (N/mm) or pounds per square inch (psi). High tensile strength is essential for belts used in heavy-duty applications such as mining and construction.

Belt Width

The width of the rubber conveyor belt is a fundamental specification that influences the volume of material the belt can transport. Belt widths typically range from 300 mm (12 inches) to 2400 mm (94 inches), depending on the application. Wider belts are used for high-capacity applications, while narrower belts are suitable for lighter loads and confined spaces.

Belt Thickness

Belt thickness affects the belt’s durability and load-carrying capacity. Thicker belts offer better resistance to wear and tear, making them suitable for abrasive materials. The thickness of rubber conveyor belts can vary from a few millimeters to over 25 mm (1 inch), depending on the type of belt and its intended use.

Ply Rating

The ply rating indicates the number of fabric layers (plies) within the belt. Each ply adds strength and durability to the belt. Common ply ratings range from 2-ply to 6-ply, with higher ply ratings indicating stronger belts. Belts with higher ply ratings are used in heavy-duty applications where additional strength is required.

Cover Grade

The cover grade refers to the type of rubber compound used for the outer layer of the belt. Different cover grades offer various levels of resistance to heat, oil, abrasion, and flame. For example, an abrasion-resistant cover grade is suitable for handling sharp and abrasive materials, while a heat-resistant cover grade is essential for high-temperature applications.

Operating Temperature Range

The operating temperature range specifies the minimum and maximum temperatures the rubber conveyor belt can withstand while maintaining its performance. Belts designed for extreme temperatures have specialized rubber compounds that prevent degradation and ensure longevity. Understanding the temperature range is crucial for applications in environments with significant temperature variations.

Elongation at Break

Elongation at break measures the belt’s ability to stretch under load before breaking. It is expressed as a percentage of the original length. A higher elongation at break indicates a more flexible belt, which is beneficial in applications requiring belt flexibility and shock absorption.


Flexibility is the belt’s ability to bend without cracking or losing integrity. Flexible rubber conveyor belts are necessary for applications involving curved or complex conveyor systems. The flexibility is influenced by the type of rubber compound and the reinforcement materials used in the belt construction.


Adhesion measures the bond strength between the rubber layers and the reinforcement materials. High adhesion values are essential to prevent delamination and ensure the belt remains intact under various operational conditions. Adhesion is particularly important for belts used in high-impact and heavy-load applications.


The weight of the rubber conveyor belt affects the ease of installation and the energy required for its operation. Lighter belts are easier to handle and require less power to operate, making them suitable for applications with lower load requirements. Conversely, heavier belts are used in demanding applications where durability and load capacity are paramount.
