This industrial pulley with a 350 mm diameter, one groove and section A is a power transmission part manufactured by EMMAR Accesorios Industriales. It is used to mount on shafts and transmit motion through section A V-belts, in machines that need a simple and reliable transmission ratio. Its metal construction and machined groove allow correct seating of the belt, which reduces wear and keeps the rotation speed stable in the equipment.

The pulley 350 1A has a 350 mm diameter, a single groove and section A. It is an in-house manufactured pulley, EMMAR brand, designed for shafts that rotate at medium speeds and that require transmitting power through a section A V-belt. The groove is machined so that the belt seats evenly and does not come off during operation. It is mounted on the shaft with the corresponding fastening system according to the equipment, and can have a keyway or a taper bushing, depending on how the assembly is set up.

This type of pulley appears in industrial fans, compressors, centrifugal pumps, conveyor belts and machine tools. It is also used in refrigeration equipment, mixers and low and medium power transmissions where a fixed transmission ratio is needed. Being single-groove, it is common in applications where it is not necessary to add several belts in parallel, or where mounting space is limited and a simple transmission is prioritized.

To choose it correctly, take into account the outer diameter, the belt section and the number of grooves. Verify that the shaft has the diameter and keyway length compatible with the pulley bore, and that the center distance allows the adequate belt. The alignment between driving and driven pulleys is key: if they are misaligned, the belt wears quickly and noise appears. Also check the balancing if the equipment rotates at high speed.

If you need a different size or a pulley with more grooves, send us the part number POLEA 350 1A or the complete designation by WhatsApp. We can quote a pulley of the same section A with another diameter, or move to a two or three groove pulley if your transmission requires it. We also advise you on the bushing or fastening that best suits your machine shaft, always confirming the measurements against a drawing or sample.
