The 300 3C pulley is a V-belt drive pulley, section C, with three machined grooves and an outside diameter of 300 mm. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good belt grip are required. It is an in-house manufactured part, EMMAR brand, designed to replace worn pulleys or to build a new drive.

This item is a three-groove pulley for section C belt, with a 300 mm diameter. The designation POLEA 300 3C summarizes those three variables: size, number of grooves and section. The grooves are machined so that the belt seats evenly and does not slip. Being section C, it accepts belts of that profile, which are the ones used when medium power needs to be moved with generously sized pulleys.

It is found in intensive-use machines: screw compressors, centrifugal fans, mills, mixers, conveyor belts and pumping equipment. Also in factory drives where a reduction or multiplication is built with two or more pulleys. Having three grooves allows the load to be distributed among several belts and adds transmission capacity without changing the diameter. It is common to see it in equipment that already came with section C pulleys and needs a replacement.

To select it, verify that the belt is section C and that the number of grooves matches the number of belts you are going to install. Check the shaft diameter and the type of keyway before ordering, because the pulley is fixed to the shaft and must fit without play. Also check the alignment between pulleys: a misalignment, even a small one, wears the belt and the grooves. If the drive works under heavy load, it is advisable to use all three grooves and not leave grooves empty.

If you need a pulley with a different number of grooves, an equivalent can be requested. For that, send the code POLEA 300 3C or the diameter and section shown on the equipment plate. A photo of the old pulley showing the grooves and the shaft also works.
