The 250 7B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 250 mm diameter, 7 grooves and section B. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, since it is in-house manufactured, we can adjust the machining to whatever your application needs. If you are assembling or replacing a drive, this pulley lets you run several grooves at once with a single body.

This item is a pulley with a 250 mm diameter, 7 grooves and section B. The designation POLEA 250 7B sums up those three variables: the 250 mm outside diameter, the number of grooves (7) and the belt profile it takes, section B. It is designed to be mounted on a shaft and to receive section B V-belts in all its grooves. Since it is in-house manufactured, EMMAR brand, we control the machining and can adapt the bore and the keyway to the shaft it will be mounted on.

Typical applications for a 7-groove section B pulley are drives that need to spread the load across several belts: screw compressors, industrial fans, mills, mixers, high-flow centrifugal pumps and conveyor lines. It is also used in woodworking machines, crushers and process equipment where torque is high and slippage needs to be reduced. With 7 grooves, the pulley can transmit more power than one with fewer grooves of the same diameter.

To select this pulley properly, take into account the pitch diameter, the number of grooves and the belt section. Section B requires a groove with standardized dimensions; if the belt is of another section, it will not fit correctly. Also check the shaft diameter, the bore length and the type of keyway. During assembly, align the pulleys with a straightedge or laser to avoid uneven wear on belts and bearings. Tension must be just right: too little tension slips, too much punishes the supports.

If you need a nearby size, another diameter, more or fewer grooves, or a pulley for another section, it can be manufactured.
