Rubber rollers are an important part of a conveyor belt system used to support the conveyor belt and transport materials. The surface of the rubber roller is covered with a layer of rubber, which can effectively reduce the wear of the conveyor belt, and at the same time play a role in shock absorption, noise reduction, and corrosion resistance. It is an upgraded form of ordinary metal rollers and is widely used in bulk material conveying systems in mining, metallurgy, electricity, ports, building materials, chemicals and other industries.
Structural composition of rubber rollers
Generally composed of three parts:
The roller body (steel pipe or plastic pipe) provides overall structural support and bears the transportation load
The rubber layer (rubber coating) is covered with rubber material, which is non-slip, wear-resistant and shock-absorbing
Bearing and sealing system: high-precision bearings + multi-channel sealing structure to ensure flexible operation, water resistance and dust resistance
Common rubber roller types
Groove roller group (three-link roller): mostly used to convey bulk materials (such as coal, ore, etc.) to form a "V"-shaped support surface, which helps to stabilize the material
Parallel roller: used to support the return conveyor belt or convey packaged materials
Buffer roller (rubber ring type): installed in the receiving section, the rubber ring buffers the impact of falling
Friction roller: used to prevent the conveyor belt from deviating, the rubber surface can provide friction guidance
Spiral roller/cleaning roller: The roller surface is a rubber spiral groove structure with self-cleaning function
Selection parameter reference
Main technical parameters include:
Roller diameter: φ63.5, φ89, φ108, φ133 mm, etc.
Length: customized according to the width of the conveyor belt
Bearing model: 6204, 6205, 6305, etc.
Rubber thickness: usually 5~12mm, set according to the use intensity
Dynamic/static load: calculated according to the conveying capacity and working conditions
Ambient temperature range: -40℃ ~ +80℃ (depending on rubber material)
