The POLEA 200 5B is a V-belt pulley produced by EMMAR. It measures 200 mm in diameter and has five grooves cut for section B belts. In a belt drive, this pulley transfers power between parallel shafts, and by pairing it with a different diameter you set the speed ratio. Because EMMAR manufactures it in-house, the machining and balancing are controlled so the pulley runs smoothly and the belts are not subjected to unnecessary wear.

The code tells you the key details: 200 mm is the diameter, 5 is the number of grooves, and B is the belt section. Section B refers to the V-belt profile that seats in the grooves; it is not the same as sections A, C or SPB. With five grooves, you can run as many as five B-section belts side by side, which spreads the load across multiple belts. The 200 mm diameter is what you use to calculate the drive ratio when the pulley is paired with another pulley on the opposite shaft.

Typical applications include compressors, fans, centrifugal pumps, conveyors, mixers and other process equipment where motion must be transmitted between shafts that are not on the same axis. You will also find this type of drive on mills, screens and elevators. In plants that handle food, chemicals or aggregates, dust and moisture are common, so it pays to check belt alignment and tension periodically to keep the drive performing as intended.

Mounting starts with confirming that the shaft diameter and keyway match the pulley bore. Next, align the pulleys using a straightedge or a laser; even a small angular misalignment will wear the belts and the bearings. Set tension according to the belt manufacturer's instructions: too loose and the belt slips, too tight and the shaft supports are overloaded. On a multi-belt drive, replace all belts at the same time so they share the load evenly.

If you need a different number of grooves, another diameter or a different section, send the part number or the dimensions of the old pulley. To evaluate a replacement, we need the outside diameter, shaft diameter, keyway width and the belt section you are using. With those details, the technical team at MR can check what is possible within the EMMAR manufacturing line.

To request a quote for this pulley or a variant, contact us via WhatsApp with the part number POLEA 200 5B or with the measurements of the pulley you are replacing. We will respond with manufacturing options and alternatives if the bore or keyway needs to be adapted. We work with workshops, maintenance departments and industrial purchasing teams, and we ship throughout the United States and to several Latin American countries.
