The 200 4B pulley is a V-belt drive pulley, section B, with four grooves and a 200 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where the load must be distributed among several belts and a stable transmission ratio maintained. It is an in-house manufactured part, brand EMMAR Accesorios Industriales, designed to replace worn pulleys or to build a new drive from scratch.

This item is a pulley with a 200 mm diameter, 4 grooves and section B. The designation POLEA 200 4B summarizes those three data points: size, number of grooves and belt profile. Section B corresponds to a V-belt profile widely used in industrial power transmission. Having four grooves allows up to four belts of the same profile to be mounted on the same body, which distributes the effort and reduces the load on each belt.

Typical applications are equipment that works with parallel shafts and needs to transmit torque continuously: fans, centrifugal pumps, compressors, conveyor belts, mixers and factory machines. It is also used to replace original pulleys when the groove is worn or when the transmission ratio is to be changed by modifying the diameter of the driving or driven pulley.

To select and mount a pulley of this type, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. Check that the keyway and the fit correspond to the shaft, and align the pulleys with a straightedge or a laser before tensioning. Misalignment, even small, accelerates wear of the groove and the belt. Also check the condition of the grooves: a groove with burrs or wear eats belts.

If you need a pulley with another size, another number of grooves or another section, an equivalent or a nearby size within the same line can be requested. For that, it is best to send the code POLEA 200 4B or the data for the diameter, grooves and section you need, together with the shaft diameter and the type of keyway. With that data, the option that best fits the drive you are building or repairing is found.
