The 350 7B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 350 mm diameter, 7 grooves and section B. It is used to transmit power from a motor to a machine, maintaining the drive ratio and parallelism between shafts. Because it is in-house manufactured, the groove machining and balancing are controlled. It is a key part in production lines, mills, conveyor belts and pumping equipment.

This pulley has a 350 mm outside diameter, 7 grooves and section B. Section B corresponds to classic-profile V-belts, suitable for medium and high power. The 7 grooves allow the load to be distributed among several belts, which reduces the stress on each one and improves drive reliability. The 350 mm diameter defines the drive ratio together with the driving pulley. The grooves are machined with tolerances that ensure correct belt contact and prevent premature wear.

It is used in equipment that requires transmitting power with a fixed drive ratio, such as mills, mixers, conveyor belts, centrifugal pumps, fans and compressors. Also in machine tools and process equipment where the motor speed needs to be reduced or increased. Due to its size and number of grooves, it is suitable for intermediate power within section B. It is commonly found in industrial plants, workshops and agro-industrial facilities.

To correctly select the pulley, take into account the pitch diameter, the number of grooves, the belt section and the type of bushing or bore. Check that the shaft diameter matches the pulley bore and that the keyway is the right one. Installation must ensure alignment between pulleys to avoid uneven wear of belts and bearings. If the pulley is mounted on a taper bushing, follow the tightening torque recommended by the bushing manufacturer.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it. We can also evaluate an equivalent replacement if you send us the measurements of the original pulley: outside diameter, number of grooves, section and type of bore or bushing. With that data, we will quote the option that best suits your equipment. In-house manufacturing allows us to adjust the machining to your requirements.
