The POLEA 230 4C pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 230 mm diameter, 4 grooves and section C. It is used to transmit motion between shafts by means of V-belts, in installations where the load needs to be distributed across several grooves and a stable transmission ratio maintained. It is a part designed for continuous service in plants and workshops, and it is machined with the tolerances each application requires.

This item is a pulley with a 230 mm diameter, 4 grooves and section C. The designation POLEA 230 4C summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section C corresponds to a medium-size V-belt profile, and the 4 grooves allow mounting up to four belts in parallel on the same pulley. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, not a resale item.

Typical applications of a 4-groove section C pulley appear in medium and high power drives: industrial fans, centrifugal pumps, screw compressors, mills, mixers, conveyors and machine tools. In all those cases the pulley is mounted on the shaft of the driving or driven equipment, and the number of grooves defines how many belts work in parallel to distribute the load.

To select and mount this pulley, take into account the pitch diameter required by the drive calculation, the number of grooves needed according to the power and type of service, and the central bore with its keyway. Verify that the shaft has no play, that the belts are aligned between pulleys and that the tension is correct: a misaligned pulley or uneven tension wears belts and bearings prematurely. If the equipment works with shocks or frequent starts, it is advisable to oversize the number of grooves.

If you need a pulley with another number of grooves, another diameter or directly another section, it can be custom manufactured. To request an equivalent or a nearby size, send us the code POLEA 230 4C together with the shaft diameter, the keyway and the belt section you are using. With that data we confirm whether a pulley from the same family is suitable or a special manufacturing is needed, and we send you the quote.
