It is used to transmit power between parallel shafts in industrial equipment: fans, compressors, pumps, mills and conveyors. As it is in-house manufactured, EMMAR brand, variants of machining and balancing can be requested according to the application. If you need to replace an existing pulley or assemble a new drive, send us the part number and equipment data to request a quote.

This pulley has a 550 mm diameter, 3 grooves and section B. Section B is one of the most widespread V-belt sizes in industry, and with three grooves it can transmit more torque than a single-groove pulley of the same diameter. The 550 mm diameter defines the transmission ratio when combined with the pulley on the opposite shaft. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for continuous service in plant.

It is used in belt drives where speed needs to be reduced or increased between a motor and a machine. Typical applications: centrifugal and axial fans, screw and piston compressors, centrifugal pumps, mills, mixers, screens and conveyors. It also appears in mining, cement, food and water treatment equipment. In all cases, it is advisable to verify the power to be transmitted, shaft speed and type of load before defining the pulley.

To select and mount a section B pulley with three grooves, take into account the motor power, the rpm of the fast and slow shafts, and the center distance. The number of grooves and the diameter determine how many belts are needed and what final speed is obtained. Check alignment between pulleys, belt tension and groove condition: a worn groove accelerates belt wear. If the pulley is mounted on a shaft with keyway, confirm the bore diameter and type of fixing.

If you need an equivalent pulley, send us the part number POLEA 550 3B or the data of the original pulley: diameter, number of grooves, section, bore diameter and type of fixing. With that we will propose the in-house manufacturing variant that fits. We can also analyze special machining, balancing and treatments according to use. The more complete the equipment information, the faster the response.

To request a quote for this pulley or inquire about another size, send the part number via WhatsApp to MR Accesorios Industriales.
