Conveyor Drum Pulley for belt conveyor
Drum Pulleys for every function
At ALTEMA, we design and manufacture custom conveyor drum pulleys, tailored to the specific requirements of each industrial project. Whether for standard conveyors or heavier conveyor systems used in demanding environments such as mines, quarries, or ports, we are capable of efficiently meeting all demands.
With over 25 years of experience and our modern production facilities, we produce a wide range of conveyor pulleys: drive or head pulleys, tension or return pulleys, snub pulleys, or even counterweight pulleys. Made of steel or stainless steel, coated or uncoated, bi-conical or cylindrical, our teams are at your disposal to develop the most suitable technical solution for your needs.
Conveyor pulleys of all dimensions
We offer customized solutions covering a wide range of dimensions, from conveyor drum pulleys with diameters ranging from 88 to 600 mm for standard applications, to large-diameter models designed for heavy-duty use. Each conveyor belt drum can be equipped with different types of shaft/flange connections: removable tapered hubs, UCFC flange bearings, or clamping elements.
With over 10,000 conveyor belt pulleys produced each year, ALTEMA stands out as a trusted partner for all industries using conveyor belts. We work closely with our clients at every stage of their project to define the most suitable conveyor drum pulley for their operations, while ensuring reliable products with a long service life and compliance with safety requirements.

tail pulley
The tail pulley, usually located opposite the drive section, ensures precise alignment of the conveyor belt and maintains optimal tension, thereby reducing the risk of premature wear.
Head pulley
The head pulley, also known as the drive drum pulley, sets the conveyor belt in motion. We offer motorized pulleys with various types of coatings to optimize traction and minimize wear.
Snub pulley
The snub drum pulley is used to increase the contact surface between the conveyor belt and the nearest drum. It plays an essential role in ensuring effective traction and constant tension.
Take up pulley
The take-up pulley is used to adjust the belt tension based on the load being transported. This ensures smooth conveyor operation and helps prevent breakdowns caused by improper tension.
Lagging for conveyor take up drum pulley
To improve traction and protect the conveyor belt, ALTEMA offers several coating solutions for your conveyor belt drums. With 25 years of experience, ALTEMA’s expertise covers the coating profile, the lining technology used, and the preparation processes for both the drum pulley and the coating.
The coatings offered range from smooth rubber to ceramic coating, including various products such as diamond-patterned ISO 284/340, and many other options. Our solutions ensure increased durability and a long service life for conveyor drums. Depending on your needs, we also use cold bonding or hot vulcanization techniques to guarantee optimal adhesion of the coating
Shaft coupling systems for conveyor belt drum
The connections between the drum and the shaft are a crucial element in ensuring the robustness and reliability of the conveyor system. ALTEMA offers various options such as VECOBLOC removable hubs, clamping elements, UCFC flange bearings, and welded flange connections.
Clamping elements
Clamping elements operate by using the radial deformation of tapered components that form their head. When the tightening torque is applied to the screw, an axial movement is generated, allowing the conical parts to make contact. This mechanism produces a compressive force that ensures a solid connection between the drum and the shaft. The advantages of clamping elements include eliminating play between the drum pulley and the shaft and distributing the load evenly across the entire shaft diameter. This reduces wear and increases the lifespan of the components.
Universal hubs type VECOBLOC
VECOBLOC removable hubs, also known as TAPERLOCK, are detachable connections that allow a conveyor belt drum to be fixed to its shaft without the need for specific tools. This system provides a good alternative to clamping elements for users who wish to maintain a keyed connection. The advantage of this coupling system is the wide range of models available to suit various industrial applications.
