The MR industrial pulley, 260 mm, 3 grooves, section A, is a power transmission component manufactured by EMMAR Accesorios Industriales. It is used to transmit motion between shafts by means of section A V-belts, allowing the speed ratio to be adjusted according to the diameters of the driving and driven pulleys. Its three-groove construction allows greater transmission capacity than a single pulley, and its 260 mm diameter places it in medium to high torque applications. It is suitable for mounting on shafts with a keyway and is balanced to reduce vibration.

This item is a pulley with a 260 mm diameter, 3 grooves and section A, according to the designation POLEA 260 3A. Section A corresponds to classic V-belts with a 13 mm top width, and the three grooves allow three belts to be installed in parallel on the same pulley. The 260 mm diameter defines the drive ratio when combined with another pulley of the same type. The part is manufactured at MR with materials and tolerances that ensure concentricity and balance for continuous service.

Typical applications include machine tools, compressors, industrial fans, centrifugal pumps, conveyors and process equipment where power must be transmitted between distant shafts. It is also used in drive systems for mills, mixers and screens. Because it has three grooves, it is common in installations that need redundancy or greater torque capacity without increasing the diameter. It is compatible with section A belts from any manufacturer that complies with the corresponding standard.

For mounting, check that the shaft has the appropriate diameter and key, and that the pulley is aligned with the driven pulley to avoid irregular belt wear. Belt tension should be the one recommended by the belt manufacturer; excessive tension overloads the shaft bearings. When selecting, take into account the power to be transmitted, the RPM of the driving shaft and the desired drive ratio. If you need help calculating the driven pulley, contact us.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or source an equivalent one. To request a nearby size or a replacement, send us the part number POLEA 260 3A or the data of the original pulley: diameter, number of grooves, section and shaft diameter. We can also quote pulleys from other series and materials according to your application. Write to us on WhatsApp and we will reply with the most suitable option.

At MR Accesorios Industriales we have been manufacturing pulleys and other transmission components for more than 80 years. If this item does not exactly match what you need, ask us about a custom variant. Send the part number POLEA 260 3A by WhatsApp and we will quote you shortly.
