The MR industrial pulley, 280 mm with 4 grooves for section A belts, is a power transmission component designed to be mounted on shafts and transmit motion via V-belts. Its diameter and number of grooves make it suitable for applications requiring multiplied drive capacity or power distribution across several belts. As an in-house manufactured product, EMMAR brand, dimensions and balancing are controlled for stable operation.

This item is a pulley of 280 mm diameter, with 4 grooves and section A. The designation POLEA 280 4A summarizes these characteristics: the 280 mm outer diameter, the number of grooves (4) and the belt section it accepts (A). Section A corresponds to classical-profile V-belts, suitable for transmitting moderate power at common drive ratios. The pulley is manufactured at MR with materials and processes that ensure concentricity and good groove finish.

Typical applications of a 4-groove section A pulley include machine tools, compressors, fans, centrifugal pumps and drive equipment in industrial plants. It is also used in systems where redundancy is needed: by employing four belts, the failure of one does not completely stop the drive until replacement. It is common in installations that require speed adjustment by changing the diameters of the driving and driven pulleys.

To correctly select this pulley, verify that the 280 mm diameter is compatible with the allowable peripheral speed of the section A belt and with the power to be transmitted. Consider the number of grooves based on power and service conditions. During installation, ensure alignment between pulleys, proper belt tension and the use of a keyway or fastening system according to the shaft. Balancing is critical at high revolutions.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. To do so, send us the code POLEA 280 4A or indicate the dimensions you need: diameter, grooves and section. We can also advise you on the driven or driving pulley that best suits your drive ratio. The goal is for you to receive the correct part without hassle.
