The industrial pulley of 650 mm diameter, 1 groove and section B is a power transmission component that is mounted on shafts to receive V-belts. Its function is to transmit rotary motion between machines, adjusting speed according to the ratio of diameters. It is a key part in equipment that needs reliable and durable drive, such as fans, compressors or pumps. MR Accesorios Industriales manufactures it with dimensional control to ensure correct fit in the system.

This pulley has 650 mm diameter, 1 groove and section B. The designation POLEA 650 1B summarizes those characteristics: the number indicates the outside dimension in millimeters, the letter B corresponds to the V-belt profile and the 1 indicates the number of grooves. It is designed to be mounted on shafts and transmit power by means of a section B belt, which fits into the machined groove. It is an in-house manufactured part, EMMAR brand, produced locally with inspection of critical dimensions.

It is used in applications where motion must be transmitted with a single belt and a large diameter, such as industrial fans, screw compressors, centrifugal pumps, mixers and conveyors. It also appears in agricultural machines and process equipment operating with moderate transmission ratios. Being section B, it accepts intermediate powers and is compatible with standard belts of that profile. Its 650 mm diameter allows suitable peripheral speeds for driving medium and high capacity equipment.

To correctly select this pulley, take into account the shaft diameter, the type of keyway and the fastening system (set screw, cone or bushing). Verify that the belt is section B and that the number of grooves matches the transmission. Mounting must be done with the pulley clean and free of burrs, aligning the grooves with the driving pulley to avoid irregular wear. Belt tension is adjusted according to the equipment manual; excessive tension overloads the bearings and low tension causes slipping.

If you need a pulley with another size, another number of grooves or a different section, we can manufacture it or find an equivalent. For that, send us the code POLEA 650 1B or the full designation via WhatsApp, along with the shaft data and the belt you use. We can also quote a nearby size if your equipment allows it. MR Accesorios Industriales has more than 80 years in the field and manufactures housings, chains and pulleys, in addition to selling bearings and transmission products.

If you have any doubt about compatibility, consult us with as much information as possible: shaft diameter, type of keyway, center distance and power to be transmitted. With that data we will guide you so that the pulley performs its function without problems. Write to us via WhatsApp and we will quote this pulley or its equivalent.
