The 550 5B pulley is an in-house manufactured power transmission pulley, EMMAR Accesorios Industriales brand, with a 550 mm diameter and 5 grooves for section B belts. It is used to drive machine and equipment shafts where torque needs to be transmitted with several belts in parallel, for example in compressors, industrial fans, mills and conveyors. Because it is our own production, you can inquire about machining and balancing variants according to the application.

This item is a pulley with a 550 mm outer diameter, 5 grooves and section B. The designation POLEA 550 5B summarizes those three variables: size, number of grooves and belt profile. Section B corresponds to a classic industrial transmission belt profile, and the 5 grooves allow the load to be distributed across several belts, which reduces the stress on each one and improves drive continuity. Machining and balancing are adjusted according to the intended use.

It is used in belt drives of equipment that works in continuous regimes: screw compressors, centrifugal fans, mills, mixers, conveyors and process machines in general. It also appears in gear reducers and pumps when the design calls for a specific transmission ratio. In all cases it is advisable to verify the power to be transmitted, the working rpm and the number of belts needed so that the pulley works within a reasonable range.

To mount and select this pulley, take into account the shaft diameter, the type of fastening (keyway, taper bushing or set screw), the center distance and the alignment with the driven pulley. A 550 mm, 5-groove pulley is chosen when the power and rpm of the equipment require several section B belts working together. Check that the grooves are clean and free of wear, and that the belt tension is correct to avoid vibrations and slipping.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 550 5B or the data of the original pulley: diameter, number of grooves, section and shaft diameter. With that we can verify if there is an in-house manufacturing variant that fits. We can also evaluate special machining, such as keyways or bushings, as long as they are within the factory's capabilities.

To quote this pulley or inquire about a different size, write to us on WhatsApp and send us the part number POLEA 550 5B. At MR Accesorios Industriales we manufacture pulleys and other transmission components, and we advise you so that the chosen pulley works with the rest of the drive. If you have doubts about the section or the number of grooves, send us a photo or a sketch and we'll review it.
