The POLEA 160 3B pulley is a V-belt drive pulley with section B, 160 mm diameter and 3 grooves. It is used to transmit power between parallel shafts in industrial machines and equipment, where a stable drive ratio and good belt grip are required. It is in-house manufactured, EMMAR brand, so it is produced with direct control over machining and balancing. If you need to replace an existing pulley or build a new drive, this model covers medium powers with three belts working in parallel.

This item is a pulley with a 160 mm diameter, with 3 grooves for section B belts. The designation POLEA 160 3B summarizes those three data points: size, number of grooves and section. The 160 mm diameter defines the belt's tangential speed and the drive ratio when combined with another pulley in the same system. The three grooves allow distributing the load among three belts, which provides more transmission capacity and some tolerance to the failure of one of them. Section B corresponds to a belt profile widely used in medium-power industrial drives.

It is used in equipment that needs to transmit motion between a motor and a machine: compressors, fans, centrifugal pumps, conveyor belts, mixers and machine tools, among other applications. It also appears in drive systems where the goal is to reduce or increase revolutions without using a gearbox. As a three-groove pulley, it is common in installations where the power is not covered by a single belt or where the equipment must keep running even if one belt breaks. It is a wear part: it should be inspected when belts are changed.

To mount and select this pulley, take into account the shaft diameter and the type of fastening (keyway, taper bushing or set screw, as applicable), which must match the equipment. Check the alignment between pulleys: angular or parallel misalignment wears belts and grooves. Belt tension is adjusted according to the equipment manual or the belt manufacturer's recommendations. Before mounting, check that the grooves have no burrs or wear, and that the pulley rotates without eccentricity. If the pulley is mounted on a shaft with a keyway, the key must fit without play.

If you need an equivalent or a nearby size, the most practical approach is to send us the complete code of the pulley you are replacing, the number of grooves and the belt section. With that data we can see if a pulley of another size fits your drive or if it is better to manufacture it. It also helps if you tell us the shaft diameter and the type of fastening. If you do not have the code, send us a photo of the pulley and the belt, and the measurements you can take with a caliper.

At MR Accesorios Industriales we manufacture this pulley and other power transmission parts.
