What is Idler Roller and Why Do We Use Them?

Idler rollers can be manufactured to suit almost any conveyor application. Some variables include bearing brand, bearing size, diameter or series, wall thickness, seal type and material type. Different variables can be selected and customised to suit your application’s standards and specifications.

Different idler rollers are used for various processes, and some determining factors could be material type, specific gravity of the material and lump size.

Steel screws have a greater scrubbing action than rubber screws, and thus steel screw idler rollers are more effective where carryback is heavy.

An example of where a steel screw idler may be effective is an application where scrapers cannot be used to clean the belt, such as a mobile plant conveyor. At a mobile plant conveyor, fitting a scraper is not possible due to insufficient room. Another example is in a folding conveyor, which may prohibit the fitting of such devices.

DYNA Engineering design our own idler rollers with lifelong durability in mind. They are manufactured using high quality ERW tube.

Precision pressed bearing housings, quality double-sealed bearings and labyrinth seals all ensure the high standard of DYNA manufactured idlers.

DYNA Engineering idlers adhere to strict quality controls and use the latest manufacturing and equipment. This achieves superior life, reduced rolling resistance and ultimately delivers lower operating costs to our customers.

Idlers are fitted to different sections of the conveyor belt depending on the purposes of their use. There is a wide variety of idlers available; however, the four most common idlers each have particular…

Idler roller or conveyor roller is a cylindrical-shaped bar that runs and beneath a conveyor belt. Idler rollers come in a variety of shapes and sizes, each with its own set of purposes.

Idler rollers are typically used to support the weight and impact of products being moved along the belt. They also help in the product smooth and continuous flow along the belt.

Idler rollers can be self-aligning and help to keep the belt on course. The rollers are normally positioned within a metal frame and are called idler sets, depending on the construction and shape of the conveyor belt.

Some of the advantages of Idler roller Impact absorption, support for the carry and return sides of the belt, and belt tracking accuracy.

Here are some different types of Idler Rollers-

Carrying Idler 

Carrying idlers are used to carry or convey bulk material on a conveyor belt. Depending on the necessity and use, these carrying idlers are made of various materials such as heavy-gauge steel tubing or seamless steel tubing. These idlers are composed of a particular shock-absorbing compound and are designed to offer a smooth transition of bulk material for a long period of time. 

Impact Idler 

Impact idlers are used in belt loading areas where belt damage is widespread due to falling debris and repeated hits. The offered rollers help to avoid damage to the belt, idler frame, structure by absorbing impact forces. The main advantage of utilizing impact idlers is that they reduce belt damage, which is costly to repair and replace. As a result, they assist in increasing production while lowering maintenance expenses.

Return Idler 

This return idler is supported by a belt as it cycles around to be loaded again. The Return Idlers come with a steel roll and two drop brackets. Return Rubber Disc Idlers are a solution for decreasing material buildup in abrasive and sticky applications.
