The 700 7B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 700 mm diameter and 7 grooves for section B belts, which allows power to be transmitted from a drive shaft to a driven shaft with good pulling capacity. It is used in equipment that needs a stable transmission ratio and several belts working in parallel, such as mills, mixers, compressors and industrial fans. Because it is in-house manufactured, machining and balancing variants can be requested.

This pulley has a 700 mm outside diameter, 7 grooves and section B. It is a cast iron or steel pulley, depending on the application, with machined grooves for section B V-belts. The number of grooves means it can mount up to 7 belts in parallel, which distributes the load across all of them and allows more power to be transmitted than a single-groove pulley. The 700 mm diameter defines the transmission ratio when combined with the pulley on the other shaft. The keyway and the bore are machined according to the equipment shaft, so it is advisable to provide those dimensions when ordering.

It is used in belt drives on machines that start under load or run many hours per day. It appears in mills, mixers, screw compressors, centrifugal fans, screens and conveyors. Also in pumping equipment and in agricultural or road machinery where a significant reduction is needed. Because it has 7 grooves, it is common in drives where a single large-section belt is not wanted, but rather several B belts working together to distribute the load and allow partial replacements.

To select it, take into account the power to be transmitted, the RPM of the drive and driven shafts, and the type of load. The number of grooves and section B are chosen according to the power and the minimum pulley diameter allowed by the belt. Check the shaft diameter, the keyway length and the center distance. Balancing is important on large pulleys that rotate fast. If the pulley is mounted with a taper bushing or adapter sleeve, indicate the fastening system. Correct alignment and proper belt tension extend the life of the assembly.

If you need a pulley with a different number of grooves, a different diameter or a different section, it can be manufactured or an equivalent can be sourced. To do so, send us the part number 700 7B, the shaft dimension, the keyway and a photo or drawing of the original pulley. We can also quote a pulley of a nearby size if the 700 mm one does not fit in the available space. Because it is in-house manufacturing, we evaluate special machining, balancing and surface treatments according to the working environment.

To request a quote for this 700 7B pulley or ask about a variant, write to us on WhatsApp with the part number and the shaft data. At MR Accesorios Industriales we reply with the alternative that best suits your equipment. If you have the old pulley on hand, send a photo and the dimensions; with that we can confirm the replacement or manufacture a custom one.
