The 550 5B pulley is a power transmission pulley of in-house manufacturing, 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 must be transmitted with several belts in parallel, for example in compressors, industrial fans, mills and conveyors. Because it is in-house production, variants of machining and balancing can be requested according to the application.

This item is a pulley with a 550 mm outside 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 among 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 runs continuously: screw compressors, centrifugal fans, mills, mixers, conveyors and process machines in general. It also appears in gearboxes 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 required so that the pulley operates 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 pulley with 5 grooves 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 belt tension is correct to avoid vibration and slippage.

If you need an equivalent pulley, 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 will propose the 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.
