The dictionary defines a conveyor belt as a continuously moving surface used for transporting objects from one location to another. This definition doesnt capture how important your conveyor belt is to your business.
Please visit our website for more information on this topic.
Your conveyor belt is essential equipment. How much do you really know about it?
Conveyor belt technology is straightforward. An electric motor powers the system.
The belt rests on a metal plate bed or rollers. One or more pulleys drive the belt.
Conveyor belts are available in several different types. They have the same basic parts, though. Learn more here about conveyor belt parts and how they keep your operations moving.
BeltThe belt is the most obvious part of conveyor belt systems. You have many conveyor belt options for the materials and belt size. The type of product you need to move and the purpose of the conveyor belt determine which type of belt is best for your application.
Conveyor belts can be made from:
Each type of material has options within it. For example, choices for thermoplastic belts include polypropylene, polyethene, and acetal. Other options include a perforated top for drainage or a high-friction top to prevent product slippage.
MotorThe motor creates energy for the gearbox, which turns the pulleys. Motors can have different sizes, shapes, and horsepower depending on the conveyor system.
A 2hp or 3 hp motor may be sufficient for a small conveyor. Faster systems like sorters need a larger and more powerful motor. Motors use either AC or DC power.
You can control the speed and direction of the motor with a variable frequency drive or another speed control device.
PulleysPulleys serve a variety of functions in an industrial conveyor belt. They provide stable motion. They maintain tension, tracking, traction, and direction for the belt.
A conveyor belt has several different types of pulleys. The drive or head pulley drives the belt. It has external bearings and is driven by a motor and reducer.
Some conveyor systems have a snub pulley. The snub pulley increases the friction between the belt and the head pulley.
Return, idler, and tail pulleys direct the conveyor belt back to the drive pulley. The tail end pulley is at the infeed for the conveyor section. It provides tension on the belt.
The take-up pulley manages tension for the entire conveyor. It can double as a tail pulley. In the lower part of the belt, the ideal location for the take-up pulley is as close as possible to the drive pulley.
RollersRollers can support a conveyor belt or propel items without a belt. In a belt system, rollers support the belt as it returns to the infeed. Rollers are usually placed outside and underneath the conveyor.
Other types of rollers include weigh rollers and impact rollers. Weigh rollers are part of belt weighing systems. They allow functions like recording flow rates or checking inventory.
Impact rollers are rubber discs mounted on a steel tube. They cushion the belt and rollers from stress. Theyre useful when loading takes place via free fall.
Most rollers are made from steel or stainless steel. Plastic and rubber are other options.
Steel rollers are very strong and durable. They provide excellent performance in heavy-duty applications. Steel is more affordable than plastic.
Plastic rollers are made from materials like HDPE or polyurethane. These materials are strong and lightweight. Theyre quieter than steel.
BearingsBearings are the interface between moving parts on the conveyor belt. They help components rotate freely to reduce wear and tear. Other functions include:
Bearings are important for many parts of the conveyor belt, like the rollers and pulleys.
Conveyor roller bearings press into the ends of the conveyor rollers. They help the rollers to rotate smoothly. Bearings are available in different sizes based on the tube diameter, tube gauge, and shaft size.
Roller bearings are typically made from stainless steel or thermoplastic. Plastic is corrosion-resistant, non-magnetic, and non-conductive. However, its softer than steel and wont handle the same loads and speeds.
Pulley bearings are usually spherical. Each pulley shaft has one fixed bearing and one floating bearing. The bearings are made from materials such as cast iron, ductile iron, and brass.
BrakesBrakes are an essential safety feature of the conveyor belt. Brakes let you control the speed of the conveyor. They also provide emergency stop capabilities.
Brake system options include:
The best type of brakes depends on the operating conditions of your conveyor belt. An inclined or declined belt will have different braking requirements than a flat belt.
An emergency backstop brake prevents the belt from running in reverse unexpectedly. A high-speed motor needs a higher braking capacity than a low-speed motor.
FrameFrames for quality conveyor belts are usually made from steel or stainless steel. Aluminium is also an option.
Common structural shapes include beam, truss, tripod, and supporting legs. The frame may have accessories like walkways or loading and discharge chutes attached. The design of the conveyor belt frame depends on factors such as:
The frame must accommodate the belt width, length, and angle.
Joyroll supply professional and honest service.
Frames can be fixed or mobile. Fixed frames have a long, stable service life. Mobile frames are useful when you need to change locations frequently.

Conveyors, while simplistic in function, are constituted of a multitude of mechanical parts that enable durable, stable, and efficient movement. Much like a car, in its most basic form, a material-handling conveyor uses a motor (engine) and gearbox (transmission) to provide power in a continuous motion.
If youre considering a conveyor unit or system in your facility, understanding its critical components and operations can assist in routine maintenance, repairs, upgrades, and future system integrations. Each part plays an important role, and grasping the mechanical basics can help you identify when continuous improvement situations occur within a conveyor system.
A belt is one of the most common applications of conveyance technology. A multi-layered rubber (or similar material) sheeting surrounds the carcass or the core of the belt. The carcass is constructed from tightly woven fabric, intertwined with each other within the top and bottom covers of the belt. Belts are wound around the head and tail pulleys on the conveyor bed, powered by the motor. Belts are created in a multitude of materials, sizes, and functions, covering a wide range of material handling applications.
Tip: Conveyor belts are extremely durable, but when rips and tears occur, splicing and vulcanization are relatively simple methods to repair the material.
Rollers are elongated cylinders attached via bearings across a conveyor bed using gravity and low-horsepower motors to move product. Items are propelled forward from spinning roller to roller, or across a belt that is threaded over a bed of rollers.
O-rings or O-bands are rubber-based circular bands that are routed in channels on rollers. O-rings allow multiple rollers to spin, keeping constant and stable movement forward as the product passes the section. Without O-rings, a roller would only move as the product skates over it. With O-rings, rollers in front of the package spin with the previous section, ensuring the package does not stop or jam.
Tip: Its easy to diagnose when an O-ring has failed. Simply search for any rollers that are not spinning when the conveyor section is operating. A single broken O-ring wont bring a system to a halt, but multiple non-spinning rollers could cause trouble. Fortunately, O-rings are inexpensive and easy to replace.
Conveyor belts are routed through a bed structure via a pulley system to drive movement forward. Pulleys provide stable motion by maintaining belt tension, tracking, traction, and direction. Each pulley in a conveyor bed provides a different function based on its location.
Pulleys are mainly only used for belted conveyors, although some manufacturers do have chain-routed pulleys for live (continuously moving) roller applications.
The engine of the conveyor, an electric motor (or gearmotor) generates energy for the gearbox, providing power to the moving components of the unit. Placed at the discharge end, or center of the conveyor, motors can vary in size, shape, and horsepower. For a single unit, a 2hp or 3hp motor provides adequate power, while faster conveyor systems (like a sorter) require larger, more powerful motors.
Conveyor motors come in various types and sizes, depending on the specific application and conveyor configuration. Motors can be AC (alternating current) or DC (direct current) and can have different power ratings, speed capabilities, and torque outputs. Conveyor motors are typically connected to the gearbox or the conveyor pulley or roller, and their speed and direction can be controlled through a variable frequency drive (VFD) or other speed control devices.
In addition to their power and durability, conveyor motors are also known for their low maintenance requirements and ease of use. They can be easily installed, repaired, or replaced, minimizing downtime and improving overall efficiency. Conveyor motors are also energy-efficient, reducing energy consumption and costs while maintaining high-performance levels.
Also known simply as a sensor, conveyors use photo eyes to complete functions based on the status captured when product moves on a unit. As a package travels throughout a conveyor system, it passes a multitude of sensors attached to the bed sides that track its movement. This tells the conveyor control module when to stop, go, or redirect the package(s), based on the information provided by every photo eye in a system. This avoids jams and blockages and maintains efficient product flow. Photo-eyes are categorized via their sensing ability and are manufactured either as through-beam sensors, retro-reflective sensors, and diffuse reflective sensors.
A few notable manufacturers of photo-eyes include but are not limited to:
Bearings play a critical role in the smooth operation of conveyor systems. Serving as the mechanical interface between moving parts, bearings provide support, reduce friction, and facilitate the motion of the conveyor belt. They are typically mounted on conveyor rollers, pulleys, and other rotating components, allowing them to rotate freely while minimizing wear and tear. Bearings enable the efficient and reliable movement of the conveyor belt, helping to transport materials smoothly and consistently.
Properly functioning bearings are essential for preventing belt misalignment, reducing downtime, and extending the overall lifespan of the conveyor system. With their crucial role in ensuring reliable and smooth conveyor operation, high-quality bearings are a key component in maintaining the performance and productivity of conveyor systems.
Brakes are an important safety feature in conveyor systems, providing control and stability during operation. These mechanical devices are designed to halt or slow down the movement of the conveyor belt or specific conveyor components. Brakes can be applied in various ways, including drum brakes, disc brakes, and caliper brakes, depending on the specific conveyor systems requirements.
One of the key benefits of brakes in a conveyor system is enhanced safety. They can prevent conveyor belt slippage, which may occur during sudden stops or in emergency situations, reducing the risk of accidents or injuries. Brakes also allow for precise control over the conveyors speed, direction, and positioning, helping to avoid damage to materials, equipment, or personnel.
In addition to safety, brakes also provide operational flexibility. They allow for smooth and controlled stops, starts, and changes in direction, which can optimize the conveyor systems performance. Brakes enable the conveyor to handle varying loads, inclines, or declines, ensuring consistent and reliable operation.
Guardrails and supports are crucial components of a conveyor system, providing stability, safety, and structural integrity. Guardrails, typically installed along the sides of the conveyor, serve as a physical barrier to prevent materials from falling off the conveyor belt or interfering with surrounding equipment or personnel. They help to contain and guide the materials being transported, ensuring that they stay on the conveyor and do not pose a hazard to the surrounding environment.
Supports, on the other hand, are used to provide structural stability and maintain proper alignment of the conveyor belt. They are usually positioned underneath the conveyor belt and provide support to the conveyor frame, rollers, and other components. Supports are designed to withstand the weight of the conveyor system, the materials being transported, and any additional loads or impacts that may occur during operation.
Guardrails and supports are typically made of durable materials, such as steel or aluminum, to provide strength and durability to the conveyor system. They are often adjustable and customizable to accommodate different conveyor configurations, heights, and widths. Guardrails and supports may also be equipped with additional features, such as guide rails, brackets, or brackets, to ensure proper alignment, prevent material spillage, and optimize conveyor performance.
A gearbox is a critical component in a conveyor system, serving as a mechanical power transmission device that controls the speed and torque of the conveyor belt. It is typically connected to the motor and the conveyor pulley or roller, and its main function is to convert the rotational speed and torque from the motor to the desired speed and torque for the conveyor belt.
Gearboxes contain a set of gears with different sizes and arrangements, which determine the gear ratio and subsequently the output speed of the conveyor belt. The gear ratio can be adjusted to suit the specific requirements of the conveyor system, allowing for precise control over the belt speed, direction, and performance. Gearboxes can be configured with various gear types, including:
Gearboxes also provide torque multiplication, allowing the motor to generate higher torque at the conveyor pulley or roller, which is essential for overcoming the resistance and friction of the conveyor belt and the materials being transported. This enables the conveyor system to handle heavy loads, inclines, or declines, while maintaining the desired belt speed and performance.
Gearboxes play a crucial role in protecting the motor and the conveyor system. They can absorb shocks and vibrations, smooth out the power transmission, and prevent excessive wear on the motor and other conveyor components. Gearboxes also provide safety features, such as overload protection, by using clutches, brakes, or other mechanisms to prevent damage to the motor or the conveyor system in case of excessive loads or sudden stops.
