The 650 2B pulley is a V-belt drive pulley, section B, with a 650 mm diameter and two grooves. It is used to transmit power between parallel shafts in equipment working with moderate loads and medium speeds. Because it is in-house manufactured, EMMAR brand, the bore, keyway and balancing can be adapted to the needs of the equipment. It is a key part for maintaining the transmission ratio and drive performance.

This pulley has a 650 mm outside diameter, 2 grooves and section B. The designation POLEA 650 2B summarizes those three variables: the diameter, the number of grooves and the belt profile. Section B accepts V-belts of that profile, and the two grooves allow two belts to be mounted in parallel to share the load. The 650 mm diameter places it among large pulleys, typical of low-speed, high-torque shafts.

It is used in drives for mills, mixers, conveyor belts, high-flow pumps and industrial fans. It also appears in agricultural machinery and process equipment where speed must be reduced from an electric or combustion engine. In all those cases, the 650 mm pulley with two section B grooves allows the drive to be maintained with a single part and few adjustments.

To mount it, check that the shaft bore matches the pulley diameter and that the key fits without play. Align the pulleys with a straightedge or a laser to avoid uneven belt wear. Belt tension is adjusted according to the equipment manual; excessive tension stresses the bearings and low tension causes slipping. If the pulley will rotate at high speed, it should be balanced.

If you need a different size, we can manufacture a pulley with another diameter, another number of grooves or for another belt section. We can also modify the bore, add a keyway or change the material. To do so, send us the part number POLEA 650 2B or the full designation of the equipment by WhatsApp and we will send you the quote with the corresponding options.

At MR Accesorios Industriales we manufacture pulleys, split plummer block housings and ANSI roller chains. If your equipment calls for a 650 2B pulley, write to us on WhatsApp with the part number and we will reply with the quote. We can also advise you if you need to replace an existing pulley or adapt the drive to a new motor.
