The 250 2C pulley is a V-belt drive pulley, with a 250 mm diameter and two grooves for a section C belt. It is used to transmit power between parallel shafts in industrial equipment, where a defined drive ratio and good pulling capacity are needed. It is manufactured by EMMAR Accesorios Industriales, which since 1945 has produced bearing housings, chains and pulleys for the Argentine market.

This item is a pulley with a 250 mm diameter, 2 grooves and section C. The designation POLEA 250 2C summarizes those three variables: the 250 mm outside diameter, the number of grooves (2) and the belt profile it houses, section C. The diameter and the number of grooves are the data that define the drive ratio and the number of belts you can mount on the same plane. Section C indicates the type of V-belt that fits into the grooves.

Typical applications of a 2-groove section C pulley appear in power transmissions of machines and equipment: compressors, fans, pumps, conveyor belts and mills, among others. In all cases the goal is to transmit torque from a motor to a driven shaft, with the possibility of adjusting speed by changing the diameter. Having two grooves allows doubling the number of belts and distributing the load between both.

To mount and select this pulley, first verify that the shaft diameter matches the pulley bore and that the fastening system is suitable (key, set screw or taper bushing, as applicable). Then check the alignment between pulleys: angular or parallel misalignment accelerates wear on the belt and the grooves. Belt tension also matters: too low slips, too high overloads the shaft bearings. If the shaft is short, it is worth evaluating the overhang.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the full part number or the data you have: diameter, number of grooves and section. With that we can verify whether there is a pulley of another size that fits your drive, or whether it is better to manufacture a custom pulley. We can also advise you on the type of bushing or fastening system if you are not sure which one corresponds to your shaft.
