The 140 mm diameter, 1-groove, section B industrial pulley is a power transmission component that mounts on the shaft of a motor or machine to receive a V-belt. With a single groove, it transmits motion to a single belt run, making it suitable for simple drives where the number of grooves does not need to be multiplied. It is an in-house manufactured part, EMMAR brand, designed to replace worn pulleys or to build a new drive from scratch.

This item is a pulley with a 140 mm outer diameter, 1 groove and section B. The B section defines the groove profile, compatible with V-belts of that type. The 140 mm diameter and the number of grooves are the data you need to verify before ordering, because the transmission ratio and the belt's tangential speed depend on them. The part is manufactured at MR with dimensional control over the pitch diameter and groove width.

It is used in fans, compressors, centrifugal pumps, light conveyor belts and machine tools. It also appears in factory equipment and low-power drives where a small, single-groove pulley is needed to keep the assembly compact. It is commonly found as a replacement in machines that already have the shaft and belt defined, and where the pulley only needs to be replaced due to wear or breakage.

To select it, start from the belt section you already have: if it is a B, this pulley is compatible. Then verify the shaft diameter and the type of keyway or mounting, because the pulley is supplied without a machined bore unless otherwise specified. Also check the center distance and the diameter of the driven pulley so that the transmission ratio stays within the intended range. If the shaft has an uncommon diameter, it can be machined to size.

If you need a nearby size, a different diameter or more grooves, send us the part number or the designation shown on the machine. We can also quote a section B pulley with the same diameter but with two or three grooves, or a 140 mm pulley in another section if the belt changes. With the shaft data and the belt section, we will confirm the alternative that best fits.

To order it, write to us on WhatsApp with the part number POLEA 140 1B or with the designation you have on hand. MR Accesorios Industriales manufactures this pulley and can also quote machined variants. If you are unsure about the section or diameter, send us a photo of the old pulley and the shaft dimensions: with that we will reply with the correct option.
