Rollers
Rollers and Upper Carrying Stations
Carrying rollers and upper carrying stations are integral components of any conveyor belt system. They ensure precise guidance and stable movement of the conveyor belt during material transport. Smooth conveyor operation, reduced belt wear, and the overall efficiency of the conveying system largely depend on their quality and functional reliability.
At COALTEC, we do not simply manufacture carrying rollers and upper carrying stations — we develop robust, high-performance solutions designed for reliable operation in the most demanding industrial environments, from underground mining to large port terminals.
Our roller product range includes a wide variety of designs and configurations. Upon request, rollers can also be manufactured in your company’s corporate colors.
Operating Principle
A carrying roller consists of a cylindrical roller shell, a shaft, and a bearing unit with a multi-stage sealing system. During conveyor operation, the rollers rotate freely with the conveyor belt, supporting it and reducing friction. This lowers energy consumption and extends the service life of both the conveyor belt and the entire conveying system.
We place particular emphasis on protecting bearings against dust, moisture, dirt, and other harmful influences. Our carrying rollers feature optimized dust and water protection and are manufactured in accordance with international quality standards.
Precise bearing assembly with axial clearance control of no more than 0.2 mm prevents deformation, reduces rotational resistance, and ensures stable operation — even under the harshest operating conditions.
Areas of Application
Our carrying rollers are used across a wide range of industries where reliable and continuous material handling is required:
Mining industry — transportation of ore, coal, rock material, and non-metallic materials
Metallurgy — handling of coke, sinter, fluxes, and metal ores
Construction industry — transport of crushed stone, sand, cement, and other inert materials
Power generation — supply of coal and other fuels to thermal power plants
Port infrastructure — handling of grain, ore, coal, and other bulk materials with minimal losses
Processing industries — transport of raw materials in chemical, food, and other industrial sectors
Quality Control and Laboratory Testing
We stand behind the quality of every product delivered to our customers. To ensure this, we operate our own laboratory and modern test facilities. Our products are inspected at all stages of production — from initial components to the finished product.
Our qualified specialists control the following key parameters:
Radial run-out
Axial clearance
Torque (rotational resistance)
Load capacity
Dust and moisture resistance
The tests simulate real operating conditions — from dusty quarry environments to wet port terminals — ensuring consistent product performance and stability under actual working conditions.
