The 260 5B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 260 mm diameter and 5 grooves for section B belts. It is used to transmit power between parallel shafts in industrial equipment: fans, compressors, pumps, mills and conveyors. Because it is in-house manufactured, we control the machining of the grooves and the balancing, which translates into even operation and less belt wear.

This item is a pulley with a 260 mm diameter, 5 grooves and section B. The designation POLEA 260 5B summarizes those three variables: outside diameter, number of grooves and belt profile. Section B corresponds to classic V-belts with a 17 mm top width, although the groove is machined to standard for that profile. The pulley is mounted on the shaft by means of a keyway and set screw or taper bushing, depending on the configuration you request. Manufactured by MR in Argentina, with dimensional inspection of each piece.

The typical applications of a 5-groove section B pulley are drives that need to transmit considerable power with several belts in parallel: centrifugal fans, screw compressors, large centrifugal pumps, mills, mixers and belt conveyors. It is also used to replace worn pulleys or to change the transmission ratio by modifying the diameter. Having 5 grooves allows the load to be distributed and operation to continue with one less belt if you need to get by until the full set is replaced.

To correctly select this pulley, take into account the pitch diameter, not just the outside diameter, because the peripheral speed and the transmission ratio depend on it. Verify that the shaft has a compatible diameter and keyway, and that the pulley is aligned with the driven pulley: a misalignment of a few degrees shortens belt life. The tensioner must be adjusted so that the belt deflection is correct. If the equipment runs with vibration, it is advisable to check the static and dynamic balancing of the pulley.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the complete part number, the number of grooves and the diameter shown on the original part. A photo of the mounted pulley or the shaft data also works. With that we verify whether we have an in-house manufactured pulley that replaces the original or whether it has to be machined to measure. We work with standard sizes and also with special manufacturing to drawing.
