The POLEA 80 4A is a V-belt pulley with an 80 mm diameter, four grooves, and section A. It transfers motion between parallel shafts in industrial machinery, allowing speed changes based on the ratio between pulleys. Manufactured in-house under the EMMAR brand, it mounts on shafts with a keyway and is secured with a set screw or taper bushing as required.

This pulley has an 80 mm diameter, four grooves, and accepts section A belts. The part number POLEA 80 4A encodes these three details: the diameter in millimeters, the number of grooves, and the belt section. The grooves are machined to seat the V-belt properly, ensuring efficient torque transmission without slippage or uneven wear. As an in-house manufactured item, EMMAR brand, it offers flexibility in replacing sizes and groove counts.

Typical applications include section A belt drives that distribute power across four grooves, such as compressors, fans, centrifugal pumps, screens, and conveyors. It is also found in machine tools and plant equipment where space is tight and concentrating multiple grooves in a small diameter is beneficial. With its 80 mm diameter, it suits transmission ratios where the drive shaft turns faster than the driven shaft.

For installation, check that the shaft diameter matches the pulley bore and that the keyway is in good condition. Align the pulleys with a straightedge or laser before tensioning the belt; misalignment—angular or parallel—accelerates belt and groove wear. Adjust tension according to the equipment manual or with a tension gauge. If no gauge is available, the belt should deflect only slightly when pressed with a finger on the longest span. Recheck the set screw or locking bushing after the first hours of operation.

If you need a different number of grooves, another diameter, or a different section, alternatives can be evaluated within the same manufacturing line. To explore options, send the part number POLEA 80 4A along with the size you require and, if possible, a photo or sketch of the shaft and available space. Indicating the belt you use and the desired transmission ratio also helps us guide you to the right alternative.
