The 450 2A pulley is a V-belt drive pulley, with a 450 mm diameter and two grooves for section A belts. It is used to drive shafts in industrial equipment where torque must be transmitted with a defined transmission ratio. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows machining and balancing to be adjusted according to the application. If you need to replace an existing pulley or build a new drive, send us the part number and the shaft data.

This item is a pulley with a 450 mm diameter, 2 grooves and section A. The designation POLEA 450 2A summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accommodates. Section A corresponds to classic narrow-profile V-belts, and the two grooves allow more power to be transmitted than a single-groove pulley of the same diameter. Groove machining and balancing are done in our own factory, with dimensional control on every part.

Typical applications are machine tool drives, centrifugal pumps, fans, screw compressors and conveying equipment. It is also used in production lines where a stable rotation speed must be maintained on the driven shaft. Being a large-diameter pulley, it is usually mounted on low or medium speed shafts, with moderate transmission ratios. It is commonly found in equipment that already has a smaller drive pulley and needs to reduce revolutions.

To select this pulley properly, take into account the shaft diameter, the type of keyway and the fastening system. Verify that the belt section matches the groove and that the number of grooves is the same on the drive pulley and the driven pulley. Alignment between pulleys is key to avoid uneven belt wear. If the pulley is mounted with a taper bushing, confirm the bushing model before ordering it. It is also advisable to check balancing if the equipment runs at high revolutions.

If you need a different size, a nearby diameter or more grooves, it can be manufactured to order. To do so, send us the part number POLEA 450 2A or the drawing with the shaft dimensions, the keyway and the number of grooves. We can also quote an equivalent pulley if you have the data of the belt you are going to use. The idea is for the part to fit the equipment without rework and for the drive to be aligned from the first assembly.

To request a quote for this pulley or inquire about a variant, write to us by WhatsApp and send us the part number POLEA 450 2A. If you have doubts about the section or the grooves, send a photo of the old pulley and the shaft dimensions. At MR Accesorios Industriales we manufacture pulleys and also sell belts, bushings and bearings to complete the drive. With the correct data, we will reply with the alternative that best suits your equipment.
