The 270 1A pulley is a V-belt drive pulley, section A, with an outside diameter of 270 mm and a single groove. It is used to transmit motion between parallel shafts in machines and industrial equipment, where a simple and reliable transmission ratio is needed. MR Accesorios Industriales manufactures it locally, with dimensional control and balancing, so that it fits without surprises during assembly.

This item is a pulley with a 270 mm diameter, with 1 groove and section A. The designation POLEA 270 1A summarizes those three variables: the outside diameter, the number of grooves and the belt profile. Section A corresponds to classic V-belts with a 13 mm top width, although the groove is machined to standard for that profile. It is a cast iron or steel part, with hub and keyway, ready to mount on a shaft. If you need to confirm the shaft diameter or the type of hub, it is checked before manufacturing.

The typical applications of a 270 mm pulley with one groove are varied: centrifugal fans, pumps, screw compressors, light conveyor belts, mixers and machine tools. It is also used in refrigeration equipment and in low-power drives where a simple reduction or increase is sought. Because it is in-house manufactured, the hub diameter, the keyway or the balancing can be adapted to the equipment. It is common to see it in installations that already have a similar pulley and need to replace it without modifying the rest of the system.

To correctly select a section A pulley, take into account the power to be transmitted, the shaft RPM and the pitch diameter. The 270 mm outside diameter is not the same as the pitch diameter: the belt seats at the bottom of the groove, so the effective circumference is somewhat smaller. Verify that the number of grooves matches the number of belts in the equipment. During assembly, make sure the keyway and the shaft are clean, and that the pulley is aligned with the driven pulley to avoid uneven belt wear.

If you cannot find the exact size, we can manufacture a pulley to measure with the diameter, number of grooves and section you need. We can also quote an equivalent pulley if you send us the original part number or the shaft and groove dimensions. For that, send us a message on WhatsApp with the designation POLEA 270 1A or with the data of the pulley you want to replace. We reply with the alternatives that best suit your equipment.

At MR Accesorios Industriales we have been manufacturing pulleys, split plummer block housings and ANSI chains for more than 80 years. That allows us to control the entire process and adjust details such as balancing or surface treatment. If your equipment works with section A pulleys, we can help you keep the drive in condition. Write to us on WhatsApp and send us the part number or the dimensions; we advise you so that the pulley is properly mounted and lasts as long as it should.
