The POLEA 320 2B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 320 mm diameter and two grooves for section B belts. It is used to transmit power between parallel shafts in industrial machines and equipment, where a reliable transmission ratio and good belt grip are required. Because it is in-house manufactured, machining and balancing are controlled so the pulley rotates without vibration and lasts in continuous service.

This item is a pulley with a 320 mm diameter, 2 grooves and section B. The designation POLEA 320 2B summarizes those three characteristics: the outer diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic V-belts, which seat at the bottom of the groove and transmit through the flanks. The grooves are machined so the belt seats evenly and does not come off during operation.

It is used in belt drives for machine tools, compressors, fans, pumps, conveyor belts and process equipment. It also appears in gearboxes and transmission systems where more than one belt is required to distribute the load. Having two grooves allows doubling the transmission capacity compared to a single-groove pulley, while keeping the same diameter. It is common in installations where space is limited and a specific transmission ratio is needed.

To mount it, check that the shaft has the correct diameter and tolerance, and that the keyway matches the pulley's. Align the pulleys with a straightedge or laser to avoid uneven belt wear. Tension must be as recommended by the belt manufacturer: too loose slips, too tight stresses the bearings. If you are replacing an existing pulley, compare the pitch diameter, number of grooves and section before ordering. Cleaning the grooves also affects performance.

If you need a pulley with a different size, number of grooves or section, it can be manufactured to order. To do so, provide the diameter, grooves and section you are looking for, and the type of keyway or fixing. We can also evaluate replacing a pulley from another brand with an equivalent in-house manufactured one. The more data you send, the faster the response.
