The 250 5B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 250 mm diameter and 5 grooves for section B belts, which allows power to be transmitted from a drive shaft to a driven shaft with good contact ratio. It is used in equipment that needs to move loads continuously, such as fans, compressors, pumps and conveyors. Because it is in-house manufactured, machining and balancing variants can be requested according to the application.

This pulley has a 250 mm diameter and 5 grooves for section B belts. The 5B designation indicates the number of grooves and the belt section it accepts. The 250 mm outside diameter defines the drive ratio when combined with another pulley in the same system. Section B is one of the most widely used in medium-power industrial drives, and the five grooves allow the load to be distributed among several belts, which reduces the stress on each one and improves drive continuity.

It is used in machines that require V-belt drives: industrial fans, screw compressors, centrifugal pumps, belt conveyors, mixers and process equipment. It also appears in the drive of mills, screens and elevators. In all cases, it is advisable to verify that the driven and drive pulleys are aligned and that belt tension is adequate to avoid premature wear and loss of efficiency.

To select this pulley, take into account the pitch diameter, the number of grooves, the belt section and the type of bushing or bore required by the shaft. Check the permissible peripheral speed and balancing if it will rotate at high revolutions. During installation, align the pulleys with a straightedge or laser, check belt tension and verify that the grooves are clean and free of burrs. Careful installation extends the life of the belts and the equipment's bearings.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request a nearby size within the in-house manufacturing line. Special machining can also be evaluated, such as a tapered bore, keyway or balancing. To request an equivalent, send the part number POLEA 250 5B or the current dimensions: diameter, grooves and section. With that data, a similar pulley is confirmed or an alternative is proposed.
