Standard Belt Conveyor Pulley Types

Belt conveyor pulleys are essential components that ensure the smooth and efficient operation of conveyor systems. From driving the belt to maintaining proper tension and alignment, each type of pulley serves a specific function in material handling applications.

Although MNSTACKER are manufactured for many years of reliable service, many factors such as corrosive environments, ambient weather conditions and proper maintenance can influence the longevity of components. We can offers a wide variety of OEM replacement conveyor pulleys, shafts and bearings. Although a completelist of replacement parts is well beyond the scope of this document, we encourage you to contact our knowledgeable staff for assistance in identifying the required components.

Conveyor Pulley Types

Pulleys are manufactured in a wide range of sizes, consisting of a continuous rim and two end discs fitted with hubs. In most of the conveyor pulleys intermediate stiffening discs are welded inside the rim. Below are shown typical welded pulleys or conveyor pulleys:

Steel drum-pulley
end curve crown pulley
Spiral drum conveyor pulley
Welded steel pulley with diamond grooved lagging
Welded steel pulley with grooved Lagging
Spiral Wing Conveyor pulley

Other pulleys are self-cleaning wing types are used as tail, take-up, or snub pulley where material tends to build up on the pulley face. Magnetic types of pulleys are used to remove tramp iron from the material being conveyed.

Lagged Conveyor Pulleys

These pulleys help maintain tension, guide the belt, and ensure smooth operation. There are various types of belt conveyor pulleys, each designed for specific functions and applications.

Drive Pulley
Tail Pulley
Snub Pulley
Bend Pulley
Take-up Pulley

Conveyor Pulley Diameter

Diameters of standard pulleys are:

200 mm (8”),
250 mm (10”),
315 mm (12”),
400 mm (16”),
500 mm (20”),
630 mm (25”),
800 mm (32”),
1000 mm (40”),
1250 mm (50”),
1400 mm (56”),
1600 mm (64”).

We have stopped the production and sales of conveyor pulleys with diameters of 200 mm, 250 mm, and 315 mm.

The pulleys may be straight faced or crowned. The crown serves to keep the belt centered. The height of the crown is usually 0.5% of the pulley width, but not less than 3 mm (1/8”).

Conveyor Drive Pulleys and Snub Pulleys

The drive pulley may be lagged by a rubber coating whenever necessary, to increase the coefficient of friction. The lagging thickness shall vary between 6 mm (1/4”) to 12 mm (1/2”). The hardness of rubber lagging of the pulley shall be less than that of the cover rubber of the running belt.
