The 450 6B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 450 mm diameter, 6 grooves and section B. It is used to transmit power between parallel shafts in industrial equipment, with the advantage of allowing various speed ratios depending on the combined diameter. Being in-house manufactured, dimensions and balancing are controlled for stable operation.

This pulley has a 450 mm outer diameter, 6 grooves and section B. Section B corresponds to classic profile V-belts, suitable for medium power and moderate peripheral speeds. The 6 grooves allow the load to be distributed among several belts, which increases transmission capacity and provides redundancy: if one belt fails, the remaining ones keep transmitting until it is replaced. The 450 mm diameter defines the transmission ratio when combined with another pulley in the same system.

It is used in machines that require transmitting power with a certain distance between shafts: screw compressors, industrial fans, mills, mixers, conveyor belts and pumping equipment. It is also common in the field, in combine harvesters and agricultural implements that work with section B belts. Having 6 grooves, it is suitable for applications where high torque needs to be transmitted without resorting to larger section belts.

To mount it, verify that the shaft has the correct diameter and key according to the pulley bore. Align the pulleys with a straightedge or laser to avoid uneven wear of belts and bearings. Belt tension is adjusted according to the equipment manual or with a tension gauge: too little tension slips, too much overloads the bearings. Check that all grooves are clean and free of burrs. If the pulley is mounted with a taper bushing, follow the screw torque indicated by the bushing manufacturer.

If you need an equivalent pulley or a nearby size, send us the complete code or the current measurements: diameter, number of grooves and section. We can also manufacture a custom pulley if space allows. Being in-house manufactured, we can adjust the bore, keyway or mounting type according to your shaft. Send us the data via WhatsApp and we'll quote the 450 6B pulley or the variant you need.

MR Accesorios Industriales manufactures this pulley locally, with dimensional control and balancing. If you have doubts about compatibility with your equipment, send the code via WhatsApp and we'll advise you. We can also quote the complete assembly with section B belts and bushings if needed.
