The 220 mm industrial pulley with one groove for section B is a power transmission component that is mounted on the shaft of a machine to drive a V-belt. Its function is to transfer rotary motion from the motor to the driven equipment, maintaining correct alignment and tension. It is a key part in systems where a simple and reliable transmission ratio is needed, and its in-house manufacturing by MR Accesorios Industriales guarantees quality control.

This item is a pulley with a 220 mm diameter, a single groove and section B, according to its designation POLEA 220 1B. Section B corresponds to a standard-type V-belt profile, and having a single groove makes it suitable for single-belt drives. The 220 mm measurement refers to the pitch or outer diameter depending on the case, and it is a figure confirmed on the product page. As it is in-house manufacturing, EMMAR brand, the machining of the bore and the keyway can be adjusted according to the needs of the equipment.

The typical applications of a pulley of this type include industrial fans, centrifugal pumps, screw compressors, light conveyor belts and machine tools. In all cases the aim is to transmit power with a fixed speed ratio and simple maintenance. It is also used in refrigeration equipment and suction systems, where the drive or driven pulley must have a specific diameter to achieve the working RPM.

To mount this pulley correctly, check that the shaft diameter matches the machined bore and that the keyway is compatible. Alignment between pulleys is essential to avoid irregular belt wear and vibration. Belt tension must be adequate: neither so loose that it slips, nor so tight that it overloads the shaft bearings. If you need to select a pulley for a given transmission ratio, take into account the pitch diameter and the belt section.
