The 240 7B pulley is a V-belt drive pulley, section B, with a 240 mm diameter and 7 grooves. It is used to drive several shafts from a single motor, distributing power across the belts. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment that needs to transmit torque steadily and with low maintenance. If your machine runs on B belts, this pulley lets you build or replace the assembly without depending on imported sizes.

This pulley has a 240 mm diameter, 7 grooves and section B. The grooves are machined so that section B V-belts seat evenly, with the correct depth and angle for the belt type. Because it is in-house manufactured, EMMAR brand, the machining and balancing are controlled before it leaves the factory. The designation POLEA 240 7B sums up the three variables you need to identify it: diameter, number of grooves and section.

It is used in belt drives where the load must be spread across several grooves: screw compressors, industrial fans, mills, mixers, centrifugal pumps and conveyor lines. It also appears in agricultural machinery and in plant equipment where the motor is far from the driven shaft. With 7 grooves, the pulley can transmit more power than one with fewer grooves of the same diameter, provided the rest of the assembly is sized for it.

To mount it, check that the shaft has the correct size and fit, and that the key seats without play. Align the pulley with the drive pulley using a straightedge or a laser alignment tool: a misalignment of a few degrees wears out the belts and the grooves. Tension the belts according to the equipment manual and check the tension after the first hours of operation. If the pulley is mounted with a taper bushing, follow the torque specified by the bushing manufacturer.

If you need a different size, we can manufacture a pulley with another diameter, another number of grooves or another section. For that, send us the outside diameter, the number of grooves, the belt section and the mounting type (taper bushing, shaft with keyway, etc.). We can also quote a pulley equivalent to the one you are using, if you give us the part number or the measurements taken from the equipment. The idea is that you don't have to stop the machine for a pulley that can't be sourced.

To request a quote for the POLEA 240 7B, send the part number by WhatsApp to MR Accesorios Industriales. If you have doubts about the section or the number of grooves, send us a photo of the old pulley or the shaft measurements and we will help you confirm the replacement. We handle technical inquiries Monday through Friday.
