The 400 6C pulley is a V-belt drive pulley, section C, with a 400 mm diameter and 6 grooves. It is used to drive machine and equipment shafts where torque must be transmitted with several belts in parallel. Because it is in-house manufactured, EMMAR brand, the groove machining and balancing are controlled, two key points so that the belts work evenly and last. If you need to replace a worn pulley or build a new drive, this model is quoted by WhatsApp with the part number MR-POLEA-C6-400.

This pulley has a 400 mm diameter, 6 grooves and section C. Those three data define the belt that corresponds to it and the number of strands it can mount. Section C is the one used in higher-power drives than sections A or B, and the 6 grooves allow the load to be distributed among several belts, which is useful when torque is high or when you want to reduce the risk of a single belt being overloaded. The 400 mm diameter defines the drive ratio that can be achieved combined with the driving pulley.

It is used in equipment that works with belt drives: compressors, industrial fans, mills, mixers, conveyor belts and production machines in general. It also appears in the field, in implements and irrigation equipment, and in workshops where pulleys are replaced due to wear or a change of ratio. When the original pulley no longer has the groove in good condition, or when more grooves are needed for the same power, this size is usually the one sought.

To mount it, check that the shaft has the diameter and keyway compatible with the pulley bore, and that the belt is section C. Align the pulleys with a straightedge or an alignment laser: a misalignment of a few degrees wears the grooves and the belts. Tension is adjusted according to the equipment manual or with a tension gauge; if you do not have the data, aim for the belt not to slip on start-up. Check that the grooves have no burrs or step-shaped wear before mounting.

If you cannot find the 400 6C pulley, or you need a nearby size, a different diameter or fewer grooves, send us the part number and the drive data: driving pulley diameter, belt section, number of grooves and shaft diameter. With that we can see if there is an equivalent pulley in the in-house manufacturing line, EMMAR brand, or if it is better to manufacture it to measure. We can also advise you on the belt that corresponds to this pulley.

To request a quote for this pulley or ask about an equivalent, write to us on WhatsApp and send the part number MR-POLEA-C6-400. If you have a photo of the old pulley or the data of the equipment where it is mounted, better: that way we confirm that the size and section are correct before preparing the quote. MR Accesorios Industriales manufactures and sells pulleys, and can advise you on the selection within the power transmission line.
