The EMMAR 90 4C pulley is a V-belt drive component with a 90 mm diameter, four grooves, and a section C profile. It transfers power between parallel shafts in industrial machinery where a consistent speed ratio and reliable traction are required. Because it is manufactured in-house, the machining and balancing are controlled to ensure proper belt seating and smooth operation.

The part number POLEA 90 4C tells you the key specifications: the outside diameter, the number of grooves, and the belt profile. Section C refers to wide-profile V-belts, which are common in drives with medium to high power demands. With four grooves, the load is distributed across multiple belts, reducing stress on each belt and helping maintain drive continuity.

You will find this pulley in compressors, pumps, fans, conveyors, mixers, and mills, as well as in gearboxes and other systems that require a stable speed ratio. The four-groove design is often chosen when you want some redundancy rather than relying on a single belt.

During installation, make sure the shaft and keyway are clean and free of burrs, and that the pulley fits without forcing it, as hammering can deform the grooves. Proper alignment between pulleys is critical: angular or parallel misalignment causes uneven belt and groove wear. Tension the belts according to the equipment manual or the belt manufacturer's recommendations. If you are replacing an existing pulley, verify the diameter, number of grooves, and section before mounting.

If you need a different number of grooves, another diameter, or a different section, an equivalent can be evaluated. The most efficient way is to send the part number POLEA 90 4C or the original pulley's part number, along with a photo or sketch showing the diameter, grooves, and belt type. Our in-house manufacturing line can then be checked for a match.
