The 160 4A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 160 mm diameter, 4 grooves and section A. It is used to transmit power between parallel shafts in industrial machines and equipment, where a reliable and easy-to-maintain drive ratio is needed. Since it is in-house manufactured, you can ask about machining and finishing variants for your application.

This MR pulley is identified with the part number POLEA 160 4A. Its main data are: 160 mm size, 4 grooves and section A. Section A corresponds to classic narrow-profile V-belts, suitable for moderate power and medium peripheral speeds. The 4 grooves allow mounting several belts in parallel, which increases transmission capacity and provides redundancy if one belt breaks. The 160 mm diameter defines the drive ratio when combined with another pulley in the same system.

Typical applications include industrial fans, compressors, centrifugal pumps, conveyors, mixers and machine tools. In all cases the goal is to transmit motion from an electric motor or a gearbox to the driven equipment, with a fixed speed ratio. It is also used in refrigeration equipment, extractors and suction systems, where the 4-groove pulley allows adjusting the fan speed by changing the diameter of the driving or driven pulley.

To correctly select this pulley, take into account the power to be transmitted, the speed of the faster shaft and the type of load. The number of grooves should be chosen according to the power and the service factor: the higher the power or the more shock loads, the more grooves. Check that the pitch diameter is compatible with the section A belt and that the shaft where it is mounted has the right diameter and keyway. Balancing and alignment between pulleys are key to avoiding vibrations and premature wear of belts and bearings.

If you need an equivalent pulley, the most practical thing is to send us the full part number of the original pulley, a photo of the part or a sketch with the main dimensions: outside diameter, shaft diameter, number of grooves and section. With that data we can offer you an in-house manufactured pulley with the same performance or a variant that fits your machine. We can also evaluate special machining, such as keyways, mounting holes or surface treatments.
