The 140 5B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 140 mm diameter, 5 grooves and section B, which makes it suitable for driving several shafts at once from a single line. It is used in equipment where power needs to be distributed with a fixed transmission ratio, such as fans, pumps, compressors and conveyors. Because it is in-house manufactured, machining and balancing variants can be requested according to the application.

This item is a pulley with a 140 mm diameter, 5 grooves and section B. The designation POLEA 140 5B summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section B grooves allow mounting V-belts of that profile, and the five grooves make it possible to transmit more torque than a pulley with fewer grooves of the same diameter. The part is manufactured at MR and is supplied with the keyway and bore machined according to the shaft it will be mounted on.

Typical applications of a 5-groove section B pulley are equipment that needs to distribute power among several shafts or maintain a stable speed under variable load. It appears in centrifugal fans, water pumps, screw compressors, belt conveyors and continuous process machines. It is also used to replace worn pulleys or to assemble a new drive when the calculation calls for five belts instead of three or four.

To mount and select this pulley, first check the shaft diameter and the keyway length, because the bore is machined to size. Then confirm the center distance and the belt length: with a 140 mm diameter and 5 grooves, the pulley fits transmission ratios where the driven shaft turns faster or slower depending on the mating pulley. Also check the alignment between pulleys, because misalignment accelerates wear on the grooves and the belts.

If you need a nearby size or an equivalent, send us the part number POLEA 140 5B by WhatsApp along with the shaft diameter, the number of grooves and the belt section you are using. With that data we can see whether a pulley of another diameter, with more or fewer grooves, is better, or whether the bore machining needs to be adjusted. We can also check whether the pulley is balanced for the working speed.

MR Accesorios Industriales manufactures this pulley and sells it together with belts, bushings and power transmission supports.
