The 250 mm industrial pulley with 8 grooves section C is a power transmission component designed to be mounted on shafts and to receive V-belts. It is used to transmit motion between parallel shafts in industrial equipment, allowing the speed ratio to be adjusted according to the diameter of the pulleys involved. Its in-house manufacturing construction, EMMAR Accesorios Industriales brand, allows replacing worn pulleys or assembling new drives with sizes and grooves made to order.

This item is a pulley of 250 mm diameter, with 8 grooves and section C. The designation POLEA 250 8C summarizes those three variables: the 250 mm outer diameter, the number of grooves (8) and the belt profile that corresponds to it, section C. The grooves are machined so that section C V-belts seat correctly and transmit torque without slipping or wearing prematurely. It is an in-house manufactured part, EMMAR brand, designed to replace standard pulleys in existing transmission lines.

Typical applications of an 8-groove section C pulley appear in drives that need to distribute load among several belts: screw compressors, high-flow industrial fans, mills, mixers, conveyor belts and pumping equipment. When the torque is high or the pulley has a considerable diameter, using several grooves allows reducing the tension per belt and increasing the service life of the assembly. It is also used in machines where a certain redundancy is required: if one belt fails, the remaining ones keep transmitting.

To mount and select this pulley, take into account the shaft diameter, the type of keyway and the fastening system (set screw, cone or bushing). Check that the belt section matches profile C and that the number of grooves is adequate for the power to be transmitted. Alignment between drive and driven pulleys is key: angular or parallel misalignment accelerates wear of belts and grooves. If you are replacing an existing pulley, it is advisable to measure the outer diameter, the total width and the number of grooves before ordering.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be manufactured or a nearby size can be found within the power transmission line. To request an equivalent, send us the part number POLEA 250 8C or the data of the original pulley: diameter, grooves, section and type of mounting. With that information we will send you the corresponding quote.
