A 240 mm sheave with three section C grooves, the POLEA 240 3C is built by EMMAR in our own shop and used to move power from a motor shaft to a driven machine through V-belts. Maintenance and purchasing teams pick this size when the drive calls for a set transmission ratio and enough belt capacity to split the load across three belts running side by side.

Read the code first: 240 is the diameter in millimeters, 3C tells you there are three grooves cut for section C belts. Section C is the deeper profile, so it suits drives that carry more power than sections A or B. With three grooves you spread the pull over three belts instead of one, which is how these sheaves are normally specified.

Where you will see it: mills, mixers, compressors, high-flow centrifugal pumps, induced draft fans, and other transmission points in process plants. Agricultural implements that need high torque use it too, as do metallurgical shops running test benches. As long as the shaft and belt match, it handles the link between motor and machine, with the speed ratio set by the two sheave diameters.

Selection comes down to a few checks. Pitch diameter is what matters, and it is not the same as the outside diameter, so confirm it lines up with your section C belt. Groove count should meet or exceed the number of belts you intend to run; a three-belt drive is a direct fit here. Then verify shaft diameter and the keyway or fastening method. At installation, align the sheaves so belts and bearings do not wear early, and watch balance at higher speeds. Vibration usually points to a concentricity problem or a worn shaft.

If the size, groove count, or section you need is different, we can make it. We can also look at replacing a sheave from another brand: send the outside diameter, shaft diameter, overall width, groove count, and section, and we will quote an equivalent. Drawings or a physical sample both work. The goal is to avoid rebuilding the whole drive around one part.

To order this sheave or an equivalent, send the part number POLEA 240 3C by WhatsApp to MR Industrial Accessories. That is enough for us to identify the item and prepare your quote. If the section or groove count is unclear, attach a photo of the old sheave or the shaft dimensions. Ask us about other power transmission parts as well.
