The POLEA 80 3A is a V-belt pulley from EMMAR, designed to transmit motion between parallel shafts in industrial machinery. It has an 80 mm diameter, 3 grooves, and accepts section A belts. Because it is manufactured in-house, the bore, keyway, and balancing can be machined to match your specific shaft and operating conditions.

The part number POLEA 80 3A tells you the three key dimensions: 80 mm diameter, 3 grooves, and section A profile. Section A is a classic narrow V-belt profile suited to moderate power and medium speeds. With three grooves, the pulley can distribute load across multiple belts, which helps reduce slip when you need more capacity or finer speed ratios.

You will find this pulley in drives for machine tools, compressors, fans, centrifugal pumps, light conveyor belts, and general factory equipment. It also works as a replacement for worn pulleys or when building a new drive from scratch. The three grooves let you fine-tune the transmission ratio by changing the number of belts or the pulley diameter.

When selecting this pulley, confirm that the 80 mm diameter fits your desired ratio and that the 3 section A grooves match your belts. The bore must be machined to the exact shaft diameter with the correct tolerance and keyway. Proper alignment between pulleys and even belt tension are critical to avoid uneven wear. For high-speed operation, check balancing before putting it into service.

If you need an equivalent, send the part number POLEA 80 3A or the drive data: shaft diameter, number of grooves, belt section, and speed ratio. We can also evaluate variants in groove count or diameter if your application requires it.
