The 250 mm pulley with one groove for a section B belt is a power transmission component that is mounted on shafts to drive machines by means of V-belts. Its diameter and number of grooves make it suitable for applications where a specific transmission ratio is required with a single belt. Manufactured by MR, this pulley is integrated into transmission systems in industrial plants, workshops and continuous process equipment.

This item is a pulley with a 250 mm diameter, 1 groove and section B. The designation POLEA 250 1B indicates those three characteristics: size, number of grooves and belt section. Section B corresponds to type B V-belts, and the single groove allows transmitting the movement of a single run. The 250 mm diameter defines the pitch circumference and, therefore, the tangential speed depending on the shaft RPM.

It is used in belt drives where speed needs to be reduced or increased between parallel shafts. It is common in fans, centrifugal pumps, compressors, conveyors and machine tools. It is also used in simple drive equipment, where a single belt is enough for the required power. Its metal construction and groove machining ensure a correct fit with the section B belt.

To select this pulley, take into account the pitch diameter, the belt section and the number of grooves. Check that the shaft has the right diameter for the central bore (which is defined at the time of purchase) and that the key matches the keyway. Mounting must ensure alignment between pulleys to avoid irregular belt wear. Correct tension is achieved by following the belt manufacturer's recommendations.

If you need a different size or more grooves, we can manufacture a pulley to measure. To request an equivalent or a similar pulley, send us the part number POLEA 250 1B or the dimensions you need: diameter, section and number of grooves. You can also indicate the shaft diameter and the type of keyway. With that data we will quote the option that best suits your transmission.
