This 220 mm single-groove pulley for section B V-belts is a power transmission component used to transmit rotary motion from a motor to driven equipment. It mounts on a shaft and maintains alignment and tension in single-belt drives. Manufactured in-house under the EMMAR brand, it is identified by the part number POLEA 220 1B.

The designation POLEA 220 1B indicates a pulley with a 220 mm diameter, one groove, and section B compatibility. Section B refers to a standard V-belt profile, so the groove is sized to accept a single B-section belt. The 220 mm dimension is confirmed on the product page and may correspond to pitch or outer diameter depending on the reference. Because it is an in-house EMMAR product, the bore and keyway can be machined to match your shaft requirements.

Typical uses for this pulley include industrial fans, centrifugal pumps, screw compressors, light conveyor belts, and machine tools. It is also found in refrigeration equipment and suction systems where a specific pulley diameter is needed to achieve the required RPM. In each case, the goal is to transmit power with a fixed speed ratio and straightforward maintenance.

When installing, verify that the shaft diameter matches the machined bore and that the keyway is compatible. Proper alignment between pulleys prevents uneven belt wear and vibration. Belt tension should be set so the belt does not slip or overload the shaft bearings. For selecting a pulley to achieve a particular transmission ratio, consider the pitch diameter and the belt section.

If the exact size is not available, a pulley can be manufactured to your sample or drawing dimensions.
