A metal roller is one of the most widely used rollers in the industry. As the name suggests, this type of roller is made of metal material. Depending on the need, it can be made of plain iron, aluminum, or stainless steel.
Due to the lack of plastic covers or similar materials, this roller has less surface resistance compared to other rollers. Similar metal materials are also used in the design and construction of a metal roller. This type of roller has various dimensions and is mainly produced in two types: welded and pressed.
Introduction and Application of Metal Roller
A roller, especially the metal type, is a kind of movable roller that is designed and manufactured in a cylindrical shape. The main application of this equipment is to transfer loads in conveyor systems. Each roller consists of one or more rollers, which have one or more bearings inside.
These bearings allow the conveyor system to move freely. Metal material is used in the construction of this roller, and the type of metal will be determined by its application. Metal rollers are made of the following materials:
- Galvanized steel
- Iron
- Aluminum
- Stainless steel
- Carbon steel
Applications of Metal Rollers
The main application of a metal roller is in production and material transfer lines for product movement. This type of roller has better performance in terms of wear resistance compared to other rollers. Also, in terms of price, it is more affordable than other rollers.
All metal rollers are selected based on the weight, product dimensions for transportation, the amount of load tonnage, and the type of conveyor belt functionality. These rollers are used in conveyor belts to support the product weight on the belt and help with transportation in various industries. Metal rollers are most commonly used in the following industries:
- Metal production
- Pipe manufacturing
- Construction materials
- Various mines
- Chemical plants
- Food industry
- Automotive industry
Where are Metal Rollers Located?
This roller experiences the most friction in the conveyor belt. If the parts of this device are not properly balanced or are not placed on a standard level, they will have the greatest impact on other parts.
This roller, depending on its design and application, is located on the side surfaces of a conveyor system. This way it can support the weight of the belt and the transferred product. In general, multiple tests are performed on a roller to seal it and place it in its proper place.
Features and Specifications of a Metal Roller
A strong and stable metal roller is made of high-quality material. This equipment is produced in various sizes and dimensions, but it is also possible to customize the dimensions according to the need. In other words, a customer can customize them based on their needs. The features and specifications of a metal roller are as follows:
- Weight and physical shape proportional to the type of need
- Specific dimensions and maximum load bearing capacity
- Constant speed based on the transferred product
- Ambient temperature tolerance
- High resistance to moisture
- Surface resistance to erosion
Structure of Metal Roller and Sealing Arrangement of Metal Roller
In terms of material, rollers are divided into two general categories: metal and polymer. The metal type is usually made of plain iron, aluminum, cast iron, or stainless steel. This roller, in terms of structure, exists in two states: pressed or fixed parts and interchangeable or replaceable parts. In the pressed type, all its parts are assembled in a pressed manner, but replacing or repairing its parts is not easy.
In this case, this roller should be replaced. Then, to reach the desired working condition, proper sealing must be done. By sealing these parts, the amount of dust or moisture penetration will be minimized.
Components of Metal Roller
A roller, when directly connected to the motor, rotates and consequently moves the conveyor belt. This roller can do its job properly using the following components:
- Pipe
- Roller pipes are made of two types ST52 and ST37. These pipes are of the welded or hidden seam type.
- Bearings
- The most important part of a roller’s structure is its bearing type. In most cases, this part determines the life of the roller. Two bearings are used in a roller.
- Housing
- The part where the bearings and seals are installed is the housing, which is usually made of metal.
- Shaft (axis)
- The shaft of a roller is one of its most important parts that holds a roller firmly in its base.
- Seal (oil seal)
The seals are responsible for protecting the bearings to prevent dust, moisture, and damage.
- Thorn
- A thorn is a metal piece with a spring property that
