Top 12 Conveyor Rollers

Conveyor rollers have been an integral part of the assembly line. They help in conveying different goods easily and quickly during the production or manufacturing process. Indubitably, the conveyor roller is a fast and safe material handling system. It can transport simple, complex, smaller and even large volume of materials within few minutes! Conveyor rollers ease the burden of transporting heavy and bulky items. If you’re on the lookout for conveyor rollers but don’t know the specifics of the product, there is no need to worry because this guide aims to make you aware of all there is to know about conveyor rollers and how to select one that fits your requirements.

Conveyor Rollers Buying Guide

Conveyor rollers are spaced-rotating cylinders. They allow the objects to gradually skate and pass through their surface up to the terminal point. Conveyor rollers have a broad scope of applications. They have got mostly installed in packaging machines, paper making, conveying equipment. Eventually, there are a few factors that can influence this buying decision.

Roller conveyors are undoubtedly one of the most popular in the various conveyor methods and for a good reason! Whether powered by gravitational or mechanical power, roller conveyors make moving items of large volumes safe and effortless.

Classification of conveyor rollers

There is a diverse range of conveyor rollers, including gravity roller conveyor, belt-driven roller conveyor, chain-driven roller conveyor, zero pressure roller conveyor, line shaft roller conveyor, and many more. Also, the material used in the roller construction divides the conveyor rollers into more categories. Generally, conveyor rollers are an outcome of numerous materials. It can be steel & stainless steel, aluminium, Teflon coated, plastic, nylon, polyurethane rubber, etc. All these rollers have varying characteristics and serve different objectives.

There are three types of roller conveyors: manual, gravitational, and mechanical. Manual conveyors require the employment of manual force to set the material in motion on the rollers. Gravity roller conveyors are downward sloped and make use of gravity to move the material on the conveyor. Finally, mechanical conveyors are powered by electricity to set the rollers in motion, pushing the material on the conveyor ahead. When purchasing rollers alone, make sure that the roller you’ve got your eye on is compatible with the type of conveyor machine you have.

What makes a conveyor roller

A conveyor roller has several components or aspects to it. Rollers with a surface coating can increase its corrosion resistance. The diameter and thickness of the rollers determine how much weight they can handle. The maximum weight capacity that the rollers can handle is known as its load rating. If you frequently have to move heavy materials, ensure you get rollers with a higher load rating.

Type of conveyor load

While purchasing conveyor rollers, one needs to keep the conveyor load in mind. The weight and shape of the objects that move on the conveyor belt determine the type of rollers required. If the weight or load is firm and has flat bottoms such as bags, skids, boxes, etc., then gravity roller conveyors are a perfect choice. However, these rollers are not suitable for delicate or unwieldy entities like electronic components and manufacturing parts.

What size of conveyor roller is best?

Conveyor rollers come in different diameters, axel, and lengths. The size of the conveyor rollers also depends upon the load and loading conditions. If there is a heavy load, it is advisable to select large-sized rollers. It will distribute the load among the rollers. In contrast, if the conveyor load is light-weighting and have low impact, then smaller rollers can be productive as well. The arrangement of the conveyor rollers also needs equal attention. There should be an optimal arrangement to prevent any kind of obstruction in the movement of the goods/articles. The surface of the moving object should always be in contact with at least three conveyor rollers. So, figure out the ideal spacing between the rollers accordingly.

The size of the roller depends on the dimensions of the conveyor’s frame and the material to be carried. The diameter of a roller ranges from 76mm to 165mm. Rollers of larger sizes can withstand bigger and heavier loads, while smaller rollers can only handle material of lower impact and lesser size. A point to keep in mind is to make sure that three rollers are always in contact with the material being transported; this is necessary to ensure movement of the package. Therefore, you may have to decrease the space between rollers in the conveyor’s frame according to need.

The curvature of the conveyor

The curvature of the conveyor also affects the choice of conveyor rollers. Like flat-belt roller conveyors will not be suitable if there is a curve in the conveyor. Apart from this, if an object needs to cover a long distance on the conveyor for multiple security or modification checks, then a line-shaft roller conveyor could prove to be more efficient and energy-saving.

The motion of the conveyor rollers

The external environment and desired motion of the rollers have a considerable impact as well! If there is excessive heat, moisture, dirt, and dust in the working environment, it is better to install chain conveyor rollers. If the objects need to be conveyed quickly without much supervision, gravity roller or belt-driven roller conveyors are great.

A few material matters

Rollers can be made of aluminium or steel with rubber, plastic or no coating. Rollers with plastic or rubber coating increase friction and help the material slide down faster and easier. Aluminium rollers are easy to install, whereas steel rollers are more durable. Plastic rollers are primarily used in food-related industries where the rollers require to be frequently dismantled for cleaning. Untreated steel rollers in such situations could corrode and warrant frequent replacements. However, metal rollers that are durable and specifically made to use as a sustainable alternative to plastic rollers have all the pros with none of the cons.
