The 400 8C pulley is a V-belt drive pulley, section C, with a 400 mm diameter and 8 grooves. It is used to drive machine shafts from a motor, transmitting torque with a speed ratio defined by the pulley diameters. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for installations that need several belts in parallel to share the load.

This item is a pulley with a 400 mm diameter, 8 grooves and section C. The designation POLEA 400 8C sums up those three data points: the 400 mm outside diameter, the number of grooves (8) and the belt section it takes, C. The grooves are machined so that each V-belt seats evenly and runs in parallel with the others, distributing the load across the eight belts.

It is used in power transmissions where equipment with continuous demand needs to be driven: compressors, industrial fans, centrifugal pumps, mills, mixers and conveyors. It also appears in process machines and plant equipment where the motor is separate from the working shaft. With 8 grooves, it accepts several belts and can sustain the required torque without relying on a single belt.

To mount it, check that the shaft diameter and keyway match the pulley bore, and that the belt section is C. Align the pulleys in the system with a straightedge or laser before tensioning: misalignment accelerates wear on belts and grooves. Tension is set according to the equipment manual or with a tension gauge. If the pulley runs at high speeds, it is advisable to check balancing and the condition of the grooves before putting it into service.

If you need a different size, a nearby diameter or fewer grooves, an equivalent pulley within the same section C can be evaluated. To do so, send us the part number POLEA 400 8C or the data of the original pulley: diameter, number of grooves, section and shaft diameter. With that information we look for the option that best suits the transmission and confirm it against the manufacturing record.
