The POLEA 400 4B pulley is a V-belt drive pulley, section B, with a 400 mm diameter and 4 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and capacity for several belts in parallel are required. It is in-house manufactured, EMMAR brand, which allows the machining to be adjusted to the size and keyway type your application requires.

This item is a 400 mm diameter pulley with 4 grooves for section B belts. The POLEA 400 4B designation summarizes those three variables: size, number of grooves and section. Section B corresponds to a V-belt profile widely used in industrial power transmissions. With four grooves, the pulley allows four belts to be mounted in parallel on the same diameter, which distributes the load among them.

It is used in fans, compressors, pumps, mills, mixers and conveyors, among other belt-driven equipment. It also appears in agricultural machines and implements where a large diameter is needed to reduce speed or to increase the speed of the driven shaft. It is a common part in maintenance and replacement, because groove wear or a blow to the edge makes replacement necessary to avoid damaging the belts.

To select it, take into account the outside diameter, the number of grooves and the section of the belt you already use. Check the shaft diameter and the keyway type, and that the pulley fits in the available space without rubbing against the structure. If you are going to change the transmission ratio, it is also advisable to review the driven pulley and the belt length. Installation requires properly aligning the pulleys and tensioning the belts according to the equipment manual.

If you need a nearby size, a different number of grooves or a different section, an equivalent or a custom pulley can be requested. To do so, send the POLEA 400 4B part number or the data of the original pulley: diameter, grooves, section and shaft diameter. With that information, the closest option within the in-house manufacturing line is found or special machining is evaluated.
