The MR industrial pulley with a 310 mm diameter and 3 grooves for section A belts is a power transmission component manufactured by EMMAR Accesorios Industriales. It is used to transmit motion between shafts by means of V-belts, allowing the speed ratio to be adjusted according to the pulley diameters. Its in-house manufacturing construction is designed for industrial applications that require robustness and precise alignment. It is a key part in machines, equipment and production lines where reliability in transmission is needed.

This pulley has a 310 mm diameter, 3 grooves and section A. The designation POLEA 310 3A identifies these characteristics: the outer diameter of 310 mm, the number of grooves (3) and the section A belt profile. The grooves are machined to accommodate section A V-belts, which guarantees adequate contact and efficient transmission. It is an in-house manufactured pulley, EMMAR brand, which allows quality control and adaptation to specific requirements.

Typical applications include machine tools, compressors, fans, pumps, conveyors and transmission equipment in general. With 3 grooves, it allows the load to be distributed among several belts, which is useful in drives that require higher power or redundancy. It is common in installations where the speed of a driven shaft needs to be maintained from an electric motor, with the possibility of modifying the transmission ratio by changing the diameter of the driving or driven pulley.

For mounting, check that the shaft has the appropriate diameter and tolerance for the pulley bore (which is defined at the time of inquiry). It is important to align the pulleys to avoid premature wear of belts and bearings. The pulley selection must consider the power to be transmitted, the rotation speed and the number of belts required. Section A accepts a range of powers per belt; with 3 grooves a higher demand can be covered. Consult MR to define the bore, keyway and balancing according to your application.
