The POLEA 270 4B pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 270 mm diameter and 4 grooves for section B belts. It is used to transmit motion between parallel shafts in industrial equipment, allowing the drive ratio to be adjusted according to the combined diameters. Its construction seeks a balance between strength, concentricity and durability for continuous service.

This item is a pulley with a 270 mm diameter, 4 grooves and section B. The designation POLEA 270 4B summarizes those three variables: size, number of grooves and belt profile. Section B corresponds to a classic industrial transmission belt profile, and the 4 grooves allow up to four belts to be mounted on the same pulley to distribute the load. It is an in-house manufactured part, EMMAR brand, intended for replacement or for building a new drive.

Typical applications include industrial fans, centrifugal pumps, compressors, conveyor belts and machine tools. In all cases the goal is to transmit power from a motor to a driven shaft, with the possibility of varying speed by changing the diameter of the driving or driven pulley. With 4 grooves, it is suitable for medium and high power within section B, as long as the drive calculation confirms it.

To mount and select it correctly, check that the 270 mm diameter is compatible with the available space and with the desired drive ratio. Check that the shaft has the right size and keyway, and that the number of grooves matches the number of belts you will use. Alignment between pulleys is key to avoiding irregular wear. If you need another size or number of grooves, it can be manufactured to order.

If you cannot find the exact pulley you need, we can analyze a nearby size or an equivalent. For that, send us the part number POLEA 270 4B or the drive data: driving and driven pulley diameters, belt section, number of grooves and power to transmit. With that data we will guide you toward the most suitable option within our in-house manufacturing line.
