The 400 5C pulley is a section C V-belt drive pulley, with a 400 mm diameter and 5 grooves. It is used to drive shafts from a motor, reducing or increasing revolutions according to the combined diameters, and to distribute power among several shafts with a single belt. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for plant equipment that runs many hours a day and needs replacement without stopping production.

This item is a pulley with a 400 mm diameter, 5 grooves and section C. The designation POLEA 400 5C summarizes the three measurements that define the assembly: the outside diameter, the number of grooves and the belt profile that fits in each groove. Section C is the one that corresponds to wide-profile V-belts, typical of drives with considerable load. The grooves are machined so that the belt seats evenly and does not slip.

It is used in drives for mills, mixers, compressors, pumps, fans and conveyors, where power must be carried from a motor to a working shaft. It also appears in woodworking machines, crushers and plant equipment that starts under load. With 5 grooves the effort can be distributed among several belts, which extends the life of the assembly and allows work to continue if one belt breaks, until it is replaced.

To choose it correctly, take into account the shaft diameter, the type of keyway and the diameter of the motor pulley. The ratio between diameters defines the revolutions of the driven shaft. Check that the belt section matches the section C of the pulley and that the number of grooves is the same on both pulleys. During mounting, align the pulleys with a straightedge or a laser and tension the belt according to the equipment manual.
