The 160 4A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has 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 transmission ratio is needed. Being in-house manufactured, you can inquire about machining and finishing variants according to your application.

This MR pulley is identified with the part number POLEA 160 4A. Its main data are: size 160 mm, 4 grooves and section A. Section A corresponds to classic V-belts of narrow profile, suitable for moderate power and medium peripheral speeds. The 4 grooves allow mounting several belts in parallel, which increases transmission capacity and provides redundancy in case of a belt break. The 160 mm diameter defines the transmission ratio when combined with another pulley of 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 gear reducer 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 loads with shocks, the more grooves. Verify that the pitch diameter is compatible with the section A belt and that the shaft where it is mounted has the adequate diameter and keyway. Balancing and alignment between pulleys are key to avoid vibrations and premature wear of belts and bearings.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the complete part number of the original pulley, a photo of the part or a sketch with the main measurements: outer 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 adapts to your machine. We can also evaluate special machining, such as keyways, fixing holes or surface treatments.
