EMMAR POLEA 340 5B belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 340 5B and any equivalents.

This B-section V-belt pulley has a 340 mm diameter and five grooves. It transfers power between parallel shafts in industrial drives that need a steady ratio and solid load capacity. Because it is made in-house under the EMMAR brand, machining can be tailored to the application. To replace an existing pulley or set up a new drive, send the part number and we will quote it.

The code 340 5B tells you the key details: 340 mm diameter, five grooves, B section. The pulley mounts on transmission shafts and runs with B-section V-belts, common in medium-power industrial drives. Since it is made in-house under the EMMAR brand, machining and balancing stay under our control, and the finish can be adapted to the equipment where it will be installed.

You will find this pulley on fans, centrifugal pumps, compressors, conveyor belts, mixers, and machine tools. In each case it is part of a motor-reducer-machine setup, and the aim is to hold peripheral speed and ratio without slipping. With five grooves, the load is spread across multiple belts, lowering stress on each belt and extending the life of the assembly. It also serves to replace worn pulleys or to change the ratio of existing equipment.

Selecting the right pulley starts with pitch diameter, groove count, and belt section. Then check shaft diameter, keyway type, and how it fastens. During mounting, align pulleys with a straightedge or laser, tension belts to the recommended deflection, and make sure they are not misaligned, since that speeds up wear on grooves and belts. For high-speed operation, verify balancing. All these data are confirmed against the technical data sheet before manufacturing.

If you need an equivalent pulley, send the full part number, a photo of the old pulley, or the shaft and keyway measurements. With that we can see whether another pulley in the same series with a different diameter or groove count will work, or if a custom-machined part is needed. We can also review the complete assembly—belts, bushings, and housings—so the drive goes together in one go and mounting goes smoothly.

MR Industrial Accessories manufactures pulleys, split plummer block housings, and ANSI chains, and also supplies bearings, seals, bushings, and lubricants.
