The 70 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 70 mm diameter and 3 grooves for section A belts. It is used to transmit motion between parallel shafts in industrial machines and equipment. Because it is in-house manufactured, MR controls the machining and quality of each part. If you need a pulley to replace an existing one or to build a new drive, this size may be the one you are looking for.

This pulley has a 70 mm diameter and 3 grooves for section A belts. The POLEA 70 3A designation summarizes these three characteristics: diameter, number of grooves and belt section. It is manufactured by EMMAR, which guarantees that the measurements and balancing are correct for industrial use. The grooves are machined so that the belt seats properly and does not slip. It is a one-piece pulley, with no moving parts, designed to be mounted on a shaft and fastened with a key or set screw, as applicable.

It is used in belt drives for machine tools, compressors, fans, pumps, conveyor belts and factory equipment. It is also common in the field, in agricultural implements and in machines for the food industry. When an old pulley must be replaced or a different drive ratio set up, this 70 mm size with three grooves can transmit more power than a single-groove pulley while maintaining the same belt section. It is a wear part that should be checked if the belt comes off or makes noise.

To choose the right pulley, take into account the outer diameter, the number of grooves and the belt section. Section A is one of the most widely used in light and medium drives. Check that the shaft hole matches the diameter of the shaft where it will be mounted and that the key fits without play. If the pulley runs at high speeds, balancing should be checked. During assembly, align the pulleys with a straightedge or a laser so that the belt does not wear on one side. Tension is adjusted according to the machine manual.

If you need a pulley with a different number of grooves, another diameter or for a different section, we can manufacture or source it. To request an equivalent or a similar size, send us the code POLEA 70 3A or the data of the original pulley: diameter, grooves, section and shaft diameter. With that data, we will quote the option that best suits you. We can also advise you if you have doubts about the drive ratio or the type of belt required.
