For drives that need one B-section V-belt, this 250 mm pulley delivers reliable power transmission. It mounts on a shaft and is manufactured by MR, so you get a component built for industrial plants, workshops and continuous process equipment.
The part number POLEA 250 1B tells you the essentials: a 250 mm diameter, a single groove, and a B-section profile. The diameter sets the pitch circumference and, along with shaft speed, determines the belt speed. One groove means the drive uses a single belt run, which is often enough for the required power in simple equipment.
You will find this pulley in belt drives that reduce or increase speed between parallel shafts. Typical applications include fans, centrifugal pumps, compressors, conveyors and machine tools. Its metal construction and machined groove are made to fit a B-section belt correctly.
When selecting this pulley, confirm the pitch diameter, belt section and number of grooves. Check that your shaft diameter matches the central bore, which is defined when you order, and that the key fits the keyway. Proper alignment between pulleys during mounting helps prevent uneven belt wear. Set tension according to the belt manufacturer's recommendations.
Need a different size or more grooves? MR manufactures pulleys to order. To request an equivalent or a similar pulley, send the part number POLEA 250 1B or the dimensions you require: diameter, section and number of grooves. You can also include the shaft diameter and keyway type. With that information, we will quote the option that best suits your transmission.
