The 380 6C pulley is a V-belt drive pulley, manufactured by EMMAR in section C with 380 mm diameter and 6 grooves. It is used to drive shafts from a motor, distributing power across several belts to transmit more torque without slipping. It is a key part in machines that run many hours a day, where pulley alignment and balance define the service life of the belts and the equipment bearings.

This MR pulley has 380 mm diameter, 6 grooves and section C. That combination defines how many C-profile V-belts fit in the groove and what transmission ratio you can build with the motor pulley. Section C is used in medium and high power ranges, and the 6 grooves allow the load to be distributed across several belts, which reduces the stress on each one and on the shaft bearings. The part is in-house manufactured, EMMAR brand, with machined grooves and balancing for continuous operation.

It is installed in screw compressors, mills, mixers, screens, industrial fans, centrifugal pumps and transmission lines in food, ceramics, plastics and aggregate processing plants. It also appears in lifting equipment and in heavy-duty agricultural machines. In all those cases it performs the same function: taking the motor rotation and bringing it to the working shaft with the speed ratio the process requires, keeping belt tension within a stable range.

To choose it correctly, start from the motor power, the drive shaft RPM and the RPM the machine needs. With those data, the diameter of the drive pulley and the driven pulley is defined, and it is verified that section C is suitable for the power and the peripheral speed. During mounting, check that the keyway and the shaft diameter match the pulley bore, that the grooves are aligned with those of the opposite pulley and that belt tension is correct. An off-center pulley or one with uneven tension shortens belt life and punishes the bearings.

If you need a nearby size, a different number of grooves or a pulley for a different shaft, send us the equipment data: drive and driven pulley diameter, belt section, number of grooves, shaft diameter and length, keyway and working RPM. With that we look for the equivalent or manufacture the pulley to measure. We can also quote the pulley together with the belts, bushings and bearings of the same assembly so you receive everything together.

To request a quote for this 380 6C pulley or ask about a variant, write to us by WhatsApp with the part number MR-POLEA-C6-380. If you have doubts about the section, the number of grooves or the shaft diameter, send us a photo of the old pulley or the measurements taken with a caliper and we will help you confirm the replacement.
