Rollers are an essential part of Roller Conveyors Systems. Roller Conveyors are formed using different Conveyor rollers depending upon the application of Conveyor Systems. The optimum conveyor roller selection is necessary, to avoid unwanted events in the future.

If the under-capacity rollers are selected, there are chances the required life of the conveyor cannot be guaranteed.

Higher capacity of conveyor rollers will result in increased investment and so Return on Investment.

Roller conveyors are used for various applications such as conveying carton boxes, plastic crates, totes, drums of sizes, intermediate containers, pallets, heavy-duty automobile components, and many more.

Here we should note that we are discussing conveyor rollers of a "Roller Conveyors System". Roller Conveyors are used for conveying carton boxes, components, etc. They are also known as unit handling conveyors.

Gravity Conveyor Rollers move the product by way of gravity from higher heights to lower heights. Since no motor is used in these conveyors, there is no electric or any other consumption. They work on the basis of gravitational force. Gravity roller conveyors are the most widely used conveyors all over the world.

Motorized Conveyor Roller move the product with motor. Rollers have various options to run it using power. Rollers are run with sprockets, timing pulley, o groove, and poly v pulley. When controlled product speeds are required, motorized roller conveyors are used.

The conveyor rollers’ selection plays a vital role in designing a roller conveyor. The selection of conveyor rollers depends on

• The weight of the component plays important role. The weight of the component should be distributed inside the container properly. If the weight in a box is uneven, the behavior changes. In such cases, the roller pitch plays an important role.

• Load Carrying Capacity of conveyor rollers Why it is so important? One has to understand that the load-carrying capacity of a roller is distributive and not concentric.

If you have to carry a jumbo Bag Pallet of 1-ton weight, it does not mean that the weight capacity of each roller should be 1 ton.

If the size of the pallet is 1mtr x 1mtr, the load is on the area 1sqm. The rollers which will be in the area of 1 SqM, will have a load of 1 ton. This load is not on a single roller.

If there are 20 rollers in this area, the load of 1ton, will be divided into 20 rollers.

It also means that if a roller is having a length of 400mm is given a load-carrying capacity of 40Kg, it implies that you can put a load on the 400mm equally and at once. It is a distributive load. If you put the weight of 40kg on any small portion of the roller, for example 100mm, is not allowed. it is concentric.

• THE LOADING & UNLOADING CONDITIONS

The loading and unloading conditions should equally be paid off. A metallic component of 50kg, can run on a roller conveyor. But if while loading it is dropped from a height of 50mm, the roller may be damaged.

• MATERIAL OF CONSTRUCTION

The contact material of the rollers plays important role in the selection of the material for construction. Corrosive Chemicals corrode the rollers and the life of the rollers is affected. Environmental Conditions such as seashore industries require ss304 material as the humid environment reduces the life of the rollers.

In some chemical industries, the normal working conditions become humid like on the seashore which affects the roller working.

When rollers are to be used in chemical industries, the behavior of the roller material with roller material, should already be tested.

• WORKING TEMPRATURE

Extreme weather conditions are always challenging. Extreme Cold or Extreme Hot conditions may affect bearing working.
