For drives that call for a single V-belt and a straightforward ratio, the EMMAR POLEA 300 1C is a 300 mm diameter pulley with one groove in section C. It is made in-house by MR Industrial Accessories LLC, with dimensional checks and balancing, so it goes onto the shaft without assembly issues. Common installations include fans, compressors, pumps and conveyors.

The code POLEA 300 1C tells you the three key variables: 300 mm outside diameter, a single groove, and a C-section profile. Section C matches wide-profile V-belts, which are typical of medium- and high-power drives. Because MR manufactures this pulley, you can ask about other diameters, groove counts or hub styles to suit your machine.

You will find this size in centrifugal fans, screw compressors, centrifugal pumps and belt conveyors, as well as in agricultural equipment and process lines that need a single-belt speed change. With a 300 mm diameter, it usually fits shafts up to 100 mm, but the hub bore is set during the inquiry based on your actual shaft size.

For correct selection, work from the pitch diameter rather than only the outside diameter, since peripheral speed and ratio depend on it. Confirm that the belt section matches the groove and that the groove count suits the power being transmitted. At installation, align the pulley with the drive pulley and tension the belt properly to avoid uneven wear.

If you are replacing an existing pulley, send the complete part number, the section, the number of grooves and the diameter you need. A photo of the original part or the shaft dimensions also helps. With that, MR can point you to the in-house variant or adjust the design.
