The MR industrial pulley, 310 mm with 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 reliable transmission is required.
This pulley measures 310 mm in diameter, has 3 grooves and section A. The designation POLEA 310 3A identifies these characteristics: the 310 mm outside diameter, the number of grooves (3) and the section A belt profile. The grooves are machined to seat section A V-belts, which ensures proper contact and efficient transmission. It is an in-house manufactured pulley, EMMAR brand, which allows quality to be controlled and the pulley to be adapted to specific requirements.
Typical applications include machine tools, compressors, fans, pumps, conveyors and transmission equipment in general. Having 3 grooves 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 must be maintained from an electric motor, with the possibility of changing the transmission ratio by changing the diameter of the driving or driven pulley.
For mounting, check that the shaft has the diameter and tolerance suitable for the pulley bore (defined at the time of inquiry). It is important to align the pulleys to avoid premature wear of belts and bearings. Pulley selection must consider the power to be transmitted, the rotation speed and the number of belts required. Section A supports a range of power per belt; with 3 grooves a higher demand can be covered. Consult MR to define the bore, keyway and balancing according to your application.
If you need an equivalent pulley, you can send us the code POLEA 310 3A or the dimensions you require: diameter, number of grooves and section. We can also evaluate variants in other diameters or number of grooves within the in-house manufacturing line. Our technical team advises you to find the option that best suits your equipment, considering the belt type and service conditions.
