The 800 3B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has an 800 mm diameter, 3 grooves and section B. It is used to transmit power between parallel shafts in equipment requiring high torque and moderate speed, such as mills, mixers, conveyor belts and compressors. Because it is in-house manufactured, the machining and balancing are controlled for stable operation.

This pulley has an 800 mm diameter, 3 grooves and section B. Section B accepts B-profile V-belts, and the 3 grooves allow up to three belts to be mounted in parallel to distribute the load. The 800 mm diameter defines the drive ratio when combined with a smaller-diameter drive pulley. It is designed for shafts that rotate at moderate speeds and transmit high power, with good resistance to alternating bending fatigue.

Typical applications include mills, mixers, conveyor belts, screw compressors, high-flow centrifugal pumps and industrial fans. In all these cases the goal is to transmit motion from an electric motor or a gearbox to the working shaft, with the possibility of adjusting speed by varying the diameter of the drive pulley. It is also used in woodworking machines, crushers and continuous process equipment.

To select the pulley correctly, take into account the pitch diameter, the number of grooves, the belt section and the type of shaft keyway. Verify that the shaft diameter matches the pulley bore and that the keyway is the right one. Installation must be done with the shaft clean and free of burrs, using a puller or press, never by striking the pulley. After mounting, check the alignment of the pulleys with a straightedge or laser to avoid irregular belt wear.

If you need a pulley with a different number of grooves, a different diameter or a different section, we can manufacture it. We can also quote an equivalent pulley from another brand if you send us the shaft measurements, the keyway and the belt section. To do that, send us the part number MR-POLEA-B3-800 or the designation POLEA 800 3B via WhatsApp and we'll reply with the alternative that best fits your equipment.

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