The 340 5B pulley is a V-belt drive pulley, section B, with a 340 mm diameter and 5 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good load capacity are required. It is in-house manufacturing, EMMAR brand, which allows the machining to be adjusted to what each application requires. If you need to replace an existing pulley or build a new drive, send us the part number and we'll quote it.

This item is a pulley with a 340 mm diameter and 5 grooves for section B belts. The designation POLEA 340 5B summarizes those three variables: size, number of grooves and section. It is designed to be mounted on the shafts of transmission equipment and to work with section B V-belts, which are the most widely used in medium-power industrial drives. Because it is in-house manufacturing, EMMAR brand, the machining and balancing are controlled in our factory, and the finish can be discussed according to the equipment where it is mounted.

Typical applications are fans, centrifugal pumps, compressors, conveyor belts, mixers and machine tools. In all those cases the pulley is part of a motor-reducer-machine assembly, and the goal is to maintain peripheral speed and transmission ratio without slipping. With 5 grooves, the pulley distributes the load among several belts, which reduces the stress on each one and extends the life of the assembly. It is also used to replace worn pulleys or to change the transmission ratio of existing equipment.

To select a pulley properly, you have to start from the pitch diameter, the number of grooves and the belt section, and then verify the shaft diameter, the type of keyway and the fastening system. During mounting, it is advisable to align the pulleys with a straightedge or laser, tension the belts according to the recommended deflection and check that they are not misaligned, because that accelerates wear on grooves and belts. If the pulley is going to run at high speed, the balancing must be checked. All those data are confirmed against the technical data sheet before manufacturing.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the full part number, a photo of the old pulley or the shaft and keyway measurements. With that we can see whether a pulley from the same series with another diameter or number of grooves is suitable, or whether a custom-machined part is needed. We can also review the complete assembly: belts, bushings and housings, so that the drive is put together in one go and there are no surprises during mounting.

At MR Accesorios Industriales we manufacture pulleys, split plummer block housings and ANSI chains, and we also sell bearings, seals, bushings and lubricants.
