The EMMAR 120 1A is a single-groove pulley with a 120 mm diameter, designed to run section A V-belts. It mounts on a shaft and transmits motion in drives that call for a straightforward, dependable ratio. Because EMMAR produces this pulley in its own shop, the bore and other machining details can be tailored to your shaft within the limits of the series. It works as a replacement for a worn pulley or as a component in a new drive build.

The part number POLEA 120 1A tells you the three key facts: 120 mm diameter, one groove, section A. EMMAR controls the outer diameter, groove profile and center bore during manufacturing. That in-house production means the shaft seat can be machined to the size you specify, as long as it falls within the range offered for this series. Contact us to discuss tolerances and surface finishes.

Typical applications include fans, compressors, centrifugal pumps, light conveyors, mixers and machine tools—any low- to medium-power belt drive. With only one groove, this pulley suits setups where space is tight or where a single, non-redundant drive is acceptable. If your existing equipment uses a section A pulley, this 120 mm size is often a direct replacement.

When selecting, confirm the belt is section A and that the pitch diameter matches the original. Check the shaft diameter and how the pulley will be secured: keyway, set screw or taper bushing. Proper alignment between pulleys prevents uneven belt wear and vibration. For high-speed operation, verify balancing. Our team can help you choose the right option for your application.
