The 140 mm industrial pulley with one groove for a C-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 a simple and reliable transmission ratio, such as fans, compressors, pumps and conveyors. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for replacement and assembly of drives in industrial settings.

This item is a pulley with a 140 mm diameter, one groove and C section. The designation POLEA 140 1C indicates exactly those three variables: size, number of grooves and belt section. Section C corresponds to a V-belt profile larger than sections A or B, so it is used in drives that handle more power. Having a single groove, the pulley houses only one belt and is used in simple drives, without multiple grooves.

Typical applications of this type of pulley include centrifugal fans, screw compressors, centrifugal pumps, belt conveyors and machine tools. In all cases the goal is to transmit rotation from a motor to another component with a fixed speed ratio. Being C-section with a single groove, it is commonly found in medium-power equipment that does not require belt redundancy or large transmission ratios.

For mounting, check that the shaft diameter matches the pulley bore and that the keyway is in good condition. The pulley must be aligned with the drive pulley to avoid uneven belt wear and vibration. Belt tension is adjusted according to the equipment manual or the belt manufacturer's recommendations. If the pulley is mounted with a taper bushing, follow the specified torque for the fastening screws.
