The 100 2A pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, with 100 mm diameter, 2 grooves and section A. It is used to transmit motion between shafts by means of V-belts, in machines and equipment that need to reduce or increase revolutions. Its construction allows mounting on shafts with keyway and fastening with set screws or taper bushings as applicable. It is a key part to maintain the transmission ratio and the alignment of the assembly.

This pulley has a diameter of 100 mm, 2 grooves and section A. The designation POLEA 100 2A summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. The grooves are machined for section A V-belts, which defines the width and depth of the groove. The body is made of cast iron or steel depending on the manufacturing batch, and the bore is finished according to the customer's shaft. If you need to confirm the bore diameter, keyway or balancing, it is verified against a drawing before manufacturing.

It is used in fans, compressors, centrifugal pumps, conveyor belts, mixers and machine tools. Also in refrigeration equipment, exhaust fans and low and medium power drives where a fixed transmission ratio is required. Having two grooves allows doubling the torque capacity or using two belts to distribute the load and reduce slipping. It is common in installations where the process cannot be stopped due to a broken belt, since with two grooves the equipment keeps running with only one until replacement.

To select it, take into account the power to be transmitted, the RPM of the drive shaft and the driven shaft, and the pitch diameter required by the ratio calculation. Verify that the belt section matches the groove: an A belt does not fit correctly in a B groove. The alignment between pulleys must be less than 0.5 mm per each 100 mm of center distance to avoid uneven wear. The pulley is mounted with a keyway and fixed axially with a set screw, plate or taper bushing. If the shaft has a large diameter, it is advisable to evaluate a taper bushing to facilitate mounting and dismounting.

If you need a nearby size, a different diameter, more grooves or a pulley for another section, it can be manufactured to order. To request an equivalent, send the full part number, the number of grooves, the belt section and the bore diameter with keyway. If you have an old pulley, provide the outside diameter, the total width, the bore diameter and a photo of the front. With that data the part is identified and the manufacturing or the closest catalog replacement is quoted.
