The 450 mm industrial pulley with one groove for a B-section belt is a power transmission component that mounts on a machine shaft to transmit motion through a V-belt. It is used in equipment that needs to reduce or increase rotation speed, such as fans, pumps, compressors and conveyors. Its robust construction and machined groove allow stable, long-lasting operation in demanding industrial applications.

This pulley has a diameter of 450 mm, a single groove and is designed for B-section belts. Section B is one of the most widely used in medium-power industrial drives, and the groove is machined to ensure uniform contact with the belt and even wear. It is an in-house manufactured part, EMMAR brand, produced at our facilities under quality control, which ensures repeatability in replacement runs.

It is used in a wide variety of applications: centrifugal and axial fans, centrifugal pumps, screw and reciprocating compressors, belt conveyors, mixers, mills and process equipment in general. It is commonly found in installations where power must be transmitted from an electric motor or a turbine to a working shaft, with transmission ratios that depend on the diameter of the driving and driven pulleys.

To correctly select this pulley, take into account the outside diameter, the belt section, the number of grooves and the shaft diameter. Verify that the shaft diameter matches the pulley bore or plan for machining and fitting a taper bushing if necessary. Mounting must be done with the pulley properly aligned with the driving pulley to avoid premature belt wear and vibration. Belt tension must be appropriate according to the equipment manufacturer's manual.

If you need a pulley with a different size, a different number of grooves or a different section, we can manufacture it or find an equivalent. To do so, send us the part number, the full designation or a photo of the original pulley with the main dimensions. We can also advise you on the most suitable pulley for your application if you tell us the motor power, the RPM and the desired transmission ratio.
