Manufacturers and distributors relied heavily on human labor before the advent of conveyor belts. The manual handling of products placed worker safety and product quality in jeopardy. The simple system of rotating pulleys and belts streamlines product handling in every product-driven industry today.
The technology used in conveyor belts is much more sophisticated than the simple belt systems of the past. Companies choose modern belts based on the use case. For example, a woven metal belt would not handle precious stones or delicate products well. Product-handling companies that understand different types of conveyor belts and their uses can choose the safest and most efficient belt systems for their needs.
Consider some of the most widely used conveyor belt materials and their applications:
Solid, general-use belts. The most common conveyor belts are general-use belts. These solid belts typically feature materials including rubber or a fabric such as nylon, polyester, neoprene, or nitrile. Belt properties determine the conveyor belt&#;s primary applications. For example, mining and milling industries commonly use rubber to handle bulk materials including raw ore and aggregates. Grocery stores commonly use PVC conveyor belts, and airports may use neoprene, polyester, or rubber for luggage handling.
These materials may feature different coatings, thicknesses, and arrangements to deliver a range of handling properties. Some offer food safety ratings while others perform well in high temperatures. Other common properties of general-use belts may include high or low friction levels and specific bulk-handling structuring.
Some belts allow particulates to pass through rather than ride along the conveyor system . Industries may use filter belts to drain excess liquid from parts or to filter out toxins. Water treatment companies often use these types of conveyor systems during water treatment processes. Manufacturers may use metal or synthetic fibers to create filter-capable belts.
Woven metal belts. Woven belts feature interlinking chains of metal or wiring designed to allow airflow as an item moves along. Businesses commonly use woven belts to facilitate drying, cooling, and heating processes in the food, electronics, and glass-working industries, among others. Manufacturers may offer pre-fabricated woven belt designs or may custom design a woven belt to meet a customer&#;s specific application needs.
Hinged belts. Hinged belts often feature metal construction. The hinged quality of the belt gives it a flat, solid surface capable of rotating around the pulley system via interlocking hinges. Companies use hinged belts for small product, scrap, and recycling applications. Metal hinged belts are durable and can stand up to rigorous use.
Plastic interlocking belts. Plastic belts provide manufacturers and material handlers with a modular alternative to metal and fabric belts. Businesses may use plastic belts in food handling and packaging processes or in the automotive industry. Modular plastic belts work well in applications that require frequent cleaning and belt replacement.
Conveyor belts fall into many categories, depending on the manufacturer. The application always dictates the materials, construction, and style of the belt used. Some are gentle enough to transport diamonds while others can handle the impact of routine bulk-steel handling.

When we want to transfer power from one shaft to another, we use power transmission devices, such as belts, chains, and gears. In today's article, we will discuss a highly flexible and efficient power transmission device known as V-belt. V-belts get their name from their trapezoidal shape, which helps them wedge into the sheaves. Twisted synthetic fibrous tensile chords, compressed by synthetic rubber form a typical V-belt, rendering it strength and flexibility. To break the bending resistance even further, keep the operating temperature lower, and give higher capacity, V-belts come in cogged construction. As opposed to chains, V-belts do not require lubrication or maintenance. They also solve slippage and alignment problems.
The types of V-belts and their standard sizes:
There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (ranked by their sizes 3V, 5V, and 8V), and light-duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L). The letter X classifies their counterpart cogged belt. For example, the Classical V cog belt will be 3VX, 5VX, etc.
Classical V-belt:
The conventional V-belt is the most common type and has been around the longest. The Initial classical V design replaced leather belts by taking over their applications in various industries, such as agriculture, ventilation, and industrial machinery. Classical V-belts can cover a load range from fractional(less than 1 HP) to 500 horsepower. They are less efficient than narrow V-belts and generally contribute to higher bearing loads. However, classical V-belts have a high tolerance for poor operating conditions.
The general part number format is the cross-section size and the inside length in inches ( e.g., B50 is a B section of 50 inches inside measurement).
General cross-sectional dimensions that are used in the US are shown below.
Narrow V series:
Narrow belts are optimum for load transfer and force distribution because of their greater depth to width ratio. That&#;s their advantage over classical V belts. Narrow belts are also suitable for drives with high belt speeds, again, for their powerfully compact size. Narrow belts can transmit up to three times the horsepower of classical V-belts in the same drive space. They can handle drives from 1 to horsepower.
Part number designation for wedge belts is shown in belt top width followed by the nominal outside length in inches. The numerical prefix indicates the belt top width in one-eighth of an inch. For example, the 5V500 part number indicates a 5/8&#; top width with a 50.0&#; outside length.

Fractional Horsepower Belt:
With competitive price and timely delivery, haichuan sincerely hope to be your supplier and partner.
FHP light-duty V-belts are often used as single belts on drives of 1 horsepower or less. Its design is for relatively light loads. The most common applications for this V-belt type are domestic washing machines, small fans, refrigerators, and garage equipment. Light V-belts should never be used on any heavy-duty industrial applications, even if they seem to fit the classical or narrow V-belt pulley grooves.
Part number designation for FHP belts is similar to wedge. They are identified with a 2L, 3L, 4L, or 5L prefix. The numerical prefix indicates the belt top width in one-eighth of an inch, followed by the nominal outside length in inches. For example, the 3L300 part number indicates a 3/8&#; top width with a 30.0&#; outer length.
