The MR 240 mm pulley with 4 grooves, section B, is a power transmission component manufactured by EMMAR Accesorios Industriales. It is used for mounting on shafts and transmitting motion through V-belts, allowing speed multiplication or reduction depending on the combined diameters. Its robust construction makes it suitable for demanding industrial applications where reliability and good mechanical performance are required.

This item is an in-house manufactured pulley, EMMAR brand, identified as POLEA 240 4B. Its main attributes are: 240 mm size, 4 grooves and section B. This means it has a pitch diameter of 240 millimeters, four grooves for section B belts and is designed to be mounted on shafts that accept that diameter. Section B corresponds to a type of V-belt widely used in medium-power industrial drives.

Pulleys of this type are used in a wide variety of equipment: industrial fans, compressors, centrifugal pumps, conveyor belts, mixers and machine tools, among others. Their function is to transmit motion from a motor or gearbox to the driven element, adjusting the drive ratio according to the diameters of the driving and driven pulleys. The number of grooves allows the load to be distributed among several belts, increasing transmission capacity and operating safety.

To correctly select a pulley, take into account the shaft diameter, the type and number of belts, the power to be transmitted and the operating revolutions. It is essential to verify dynamic balance, especially in high-speed applications, and to ensure precise alignment between pulleys to avoid premature wear of belts and bearings. Assembly must be carried out with the appropriate fastening elements, such as keys and set screws, respecting the torque recommended by the equipment manufacturer.

If you need a pulley with a different size, number of grooves or section, we can manufacture it or find an equivalent. For that, the most practical thing is for you to send us the code POLEA 240 4B or the data of the original pulley: diameter, grooves, section and shaft diameter. With that information we will quote the option that best suits your requirement, whether from our in-house manufacturing line or from the brands we distribute.
