Conveyor Roller Non-powered Roller

Conveyor Roller Non-powered Roller

Gravity Roller Follower rollers)Unpowered rollers are cylindrical objects typically made of metal, plastic or rubber that are used in conveyor systems to move materials or products along a designated path. In order to ensure good stability, the rollers are always bolted together, which means that the conveyor rollers can carry maximum loads and can be easily replaced during maintenance. They are not driven by any external power source and rely solely on the force of gravity or manual pushing to move the objects along.Unpowered rollers can come in various shapes and sizes, depending on the specific application they are being used for. They are often found in industries such as manufacturing, distribution, and warehousing where large volumes of products need to be moved efficiently. While unpowered rollers are generally low maintenance, regular cleaning, and inspection are necessary to ensure their proper functioning and prevent damage or wear over time.

What is the difference between a gravity roller conveyor and a powered roller conveyor?

Of the two types,  gravity roller conveyors are the simplest form and operate by manually pushing the product along the surface of the roller. The term motor-driven or powered roller conveyor covers a wide range of roller conveyors, each type with a different power system.

Spindle Conditions for conveyor roller

Threaded GCS


Round spindles can be threaded at either end to suit a metric or imperial nut. In most cases, the spindle is supplied loose.

Drilled Spindle End

Drilled Spindle End

Round spindles can be threaded at either end to suit a metric or imperial nut. In most cases, the spindle is supplied loose.



External circlips can be used to captivate a spindle within a roller. This method of retention is usually found on heavy-duty rollers and drums.

Milled Flats

Drilled and Tapped

Round spindles with 2 milled flats are used in conveyors with slotted side frames where rollers are lowered into position. In most cases, the spindle is supplied fixed within the roller.

Drilled and Tapped GCS

Drilled and Tapped

Both round and hexagonal spindles can be drilled and tapped at each end to enable the roller to be bolted between the conveyor side frames, thus increasing the rigidity of the conveyor.

Un-machined round spindles are suitable for double spring loaded rollers. In some cases the sideframes could be drilled as opposed to punched.

Extruded hexagonal spindles are suitable for punched conveyor side frames. In most cases, the spindle would be spring-loaded. The hexagonal shape prevents the spindle from rotating in the side frame, it also prevents the bearing inner race from rotating on the spindle.

Frequently asked questions about conveyors roller

What Is a Conveyor Roller?

A conveyor roller is a line in which multiple rollers are installed for the purpose of transporting goods in a factory, etc., and the rollers rotate to transport the goods. They are also called roller conveyors.

They are available for light to heavy loads and can be selected according to the weight of the cargo to be transported.

In most cases, a conveyor roller is a high performance conveyor that is required to be impact and chemical resistant, as well as being able to transport items smoothly and quietly.

Inclining the conveyor allows the conveyed material to run on its own without external drive of the rollers.

What to Consider When Choosing a Roller?

Your rollers must fit your system exactly for optimal performance. Some different aspects of each roller include:

Size:  Your products and conveyor system size correlate to the roller size. The standard diameter is between 7/8″ to 2-1/2″, and we have custom options available.

Material:  We have several options for roller materials, including galvanized steel, raw steel, stainless steel and PVC. We can also add urethane sleeving and lagging.

Bearing:  Many bearing options are available, including ABEC precision bearings, Semi-precision bearings and Non-precision bearings, among other options.

Strength:  Each of our rollers has a designated load weight specified in the product description. Rolcon provides both lightweight and heavy-duty rollers to match your load sizes.

Uses of Conveyor Rollers

Conveyor rollers are used as conveyor lines to move loads from one location to another, for example, in a factory.

The conveyor rollers are suitable for conveying objects with relatively flat bottoms, as there may be gaps between the rollers.

Specific materials conveyed include food, newspapers, magazines, small packages, and many others.

The roller does not require power and can be pushed by hand or propelled by itself on an incline.

Conveyor rollers are often used in situations where cost reduction is desired.

Principle of Conveyor Rollers

A conveyor is defined as a machine that continuously transports a load. There are eight major types, of which belt conveyors and roller conveyors are the most representative.

The difference between belt conveyors and roller conveyors is the shape (material) of the line conveying the cargo.

In the former, a single belt rotates and is transported on it, while in the case of a roller conveyor, multiple rollers rotate.

The type of rollers is selected according to the weight of the cargo to be conveyed. For light loads, the roller dimensions range from 20 mm to 40 mm, and for heavy loads up to about 80 mm to 90 mm.

Comparing them in terms of conveying force, belt conveyors are more efficient because the belt makes surface contact with the material to be conveyed, and the force is greater.

Roller conveyors, on the other hand, have a smaller contact area with the rollers, resulting in a smaller conveying force.

This makes it possible to convey by hand or at an incline, and it has the advantage of not requiring a large power supply unit, etc., and can be introduced at a low cost.

How do I know what roller diameter to choose for gravity conveyors?

A typical 1 3/8” diameter roller has a capacity of 120 lbs. per roller. A 1.9” diameter roller will have an approximate capacity of 250 lbs. per roller. With rollers set on 3” roller centers, there are 4 rollers per foot, so the 1 3/8” rollers would typically carry 480 lbs. per foot. The 1.9” roller is a heavy duty roller that handles approximately 1,040 lbs. per foot. The capacity rating can also vary based on how the section is supported.
