The 700 5B pulley is a V-belt drive pulley, section B, with a 700 mm diameter and 5 grooves. It is used to drive machine shafts from a motor, transmitting torque over distance with a fixed speed ratio. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows the machining and balancing to be adjusted to the application. If you need to replace an existing pulley or build a new drive, send us the part number and the shaft dimensions.

This item is a pulley with a 700 mm diameter, 5 grooves and section B. Section B defines the groove profile for V-belts of that family; the 5 grooves allow five belts to be mounted in parallel on the same sheave. The 700 mm diameter is the outside dimension of the pulley, a figure used to calculate the peripheral speed and the ratio with the drive pulley. The bore machining, the keyway and the balancing are defined when ordering, because the pulley is manufactured according to the shaft it will be mounted on.

It is used in drives where speed must be reduced or increased between a motor and equipment: fans, compressors, centrifugal pumps, mills, mixers, conveyor belts and process machines. It also appears in lifting equipment and production lines where the drive pulley is small and the driven pulley is large. With 5 grooves the load is distributed among several belts, which lowers the tension per belt and extends the life of the assembly. It is a size commonly seen in medium and low speed installations.

To select it, start from the motor power, the input RPM and the RPM you need on the driven shaft. With those data the drive pulley diameter and the number of grooves are defined; the 700 mm diameter and the 5 grooves of this pulley are what set the final ratio. Check that the bore matches the shaft diameter, the keyway and the fastening system. Also check the center distance and the available belt length, and that the pulley has the right balancing for the working speed.

If the exact part number is not the one you need, you can request a pulley of the same section B with a different number of grooves or a different diameter, or a pulley for another type of belt. For that it is best to send the original part number, the section, the number of grooves, the diameter, the shaft diameter and the type of fastening. With those data the closest size or the equivalent within the in-house manufacturing line is found. If you don't have the data sheet at hand, a photo of the mounted pulley and measurements taken with a caliper help to identify it.

MR Accesorios Industriales manufactures this pulley in section B and machines it according to the destination shaft. To request a quote, send the part number POLEA 700 5B by WhatsApp along with the shaft diameter, the keyway and the working RPM. If the pulley goes on equipment that is already assembled, add a photo and the dimensions of the current pulley. With that the part is confirmed and the inquiry is answered.
