The 280 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 280 mm diameter and 3 grooves for section A belts. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that being in-house manufacturing we can adjust the machining to what your application needs. If you are looking for a three-groove pulley for A belts, this size is one of the most requested.

This item is a pulley with a 280 mm diameter, with 3 grooves and section A. The designation POLEA 280 3A summarizes those three characteristics: the outer diameter, the number of grooves and the belt profile. Section A corresponds to classic V-belts with a 13 mm top width, so the grooves are machined with that profile. It is an in-house manufactured pulley, EMMAR brand, designed to be mounted on shafts and transmit motion by means of belts.

It is used in machines and equipment that need to transmit power between parallel shafts: compressors, fans, pumps, conveyor belts, mixers and mills, among others. The three grooves allow distributing the load among three belts, which gives more transmission capacity and some redundancy if one belt fails. It is also chosen when you want to reduce the tension on each belt or when the available space limits the pulley diameter.

To select this pulley properly, take into account the pitch diameter, the number of grooves and the belt section. Check that the shaft where it is mounted has the adequate diameter and keyway, and that the pulley is aligned with the driven pulley to avoid uneven belt wear. If the equipment works with a lot of vibration or variable loads, it is advisable to check the balancing and the tightening of the fastening screws.

If you need a similar pulley but with another size, another number of grooves or for another belt section, we can manufacture it. Send us the code POLEA 280 3A or the data of the original pulley (diameter, grooves, section and shaft type) and we will send you a quote by WhatsApp. We can also evaluate a replacement if the pulley you have mounted is no longer available.
