The 80 1B pulley is an in-house manufactured power transmission pulley, EMMAR brand, with 80 mm diameter, a single groove and section B. It is used to transmit motion from a motor or gearbox to a driven shaft by means of V-belts. It is a key component in machines that need a simple and reliable transmission ratio, such as fans, compressors, pumps and conveyors. Its single-groove design makes it ideal for applications where a single belt and simple maintenance are required.

This pulley measures 80 mm, with one groove and section B. The designation POLEA 80 1B summarizes those three characteristics: 80 mm outside diameter, 1 groove and belt section B. It is manufactured by EMMAR, which guarantees control over machining and material quality. Section B corresponds to a V-belt profile widely used in industrial power transmissions. It is a single-groove pulley, designed for mounting on shafts up to 24 mm, although the bore diameter is confirmed at the time of the quote according to the customer's shaft.

Typical applications for this pulley include centrifugal fans, water pumps, screw compressors, belt conveyors and machine tools. It is also used in refrigeration equipment and in transmission systems where a fixed speed ratio is needed. Due to its compact size, it is common in installations where space is limited and a single belt is required. As it is in-house manufactured, MR can adapt the bore and keyway to the equipment's needs, which makes it versatile for replacements and new installations.

To correctly select this pulley, take into account the shaft diameter, the power to be transmitted, the rotation speed and the belt type. Section B accepts B-profile V-belts, and the number of grooves must match the number of belts in the system. It is important to verify the pitch diameter, which does not always coincide with the outside diameter, to calculate the transmission ratio. During assembly, make sure the pulley is aligned with the drive pulley and that the belt has the proper tension to avoid premature wear.
