The 420 2B pulley is a V-belt drive pulley with section B, two grooves and 420 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where a defined transmission ratio and good belt grip are required. Because it is in-house manufactured, EMMAR brand, the bore and keyway machining can be adapted to the shaft. If you need a pulley to replace an existing one or for new equipment, send us the part number by WhatsApp and we will quote it.

This pulley has a 420 mm diameter, 2 grooves and section B. Section B corresponds to V-belts with a B profile, which are the most widely used in medium-power industrial drives. The two grooves allow two belts to be mounted in parallel, which increases transmission capacity without changing the diameter. The body is manufactured in cast iron or steel, depending on the application, and the bore is machined with the keyway corresponding to the shaft where it is mounted. The designation POLEA 420 2B identifies exactly this size and configuration.

It is used in machines and equipment that need to reduce or increase speed between a motor and a driven machine: compressors, centrifugal pumps, fans, conveyor belts, mixers and mills, among others. It is also common in the field, in agricultural implements and in irrigation equipment. Because it is a two-groove pulley, it is often found in drives where a certain redundancy or higher torque is required, or where the load is to be distributed between two belts to reduce wear.

To correctly select a pulley of this type, you must take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. It is also important to verify the center distance and the desired transmission ratio. During assembly, make sure the pulley is aligned with the drive pulley, that the belts have the proper tension and that the keyway fits without play. If the pulley is mounted on a shaft with a bearing, it is advisable to check that there is no eccentricity.

If you need a pulley equivalent to this size, the most practical thing is to send us the part number POLEA 420 2B or the equipment data: diameter, grooves, section and shaft diameter. With that we will propose the corresponding similar in-house manufactured pulley or machine it to measure. We can also advise you on the right belt for that pulley and on the bushings or supports that may be needed for assembly.
