The 350 5B pulley is a power transmission pulley manufactured by EMMAR Accesorios Industriales. It has a 350 mm diameter, 5 grooves and section B, which makes it suitable for mounting five V-belts simultaneously. It is used in machines that need to transmit torque with a good transmission ratio, such as mills, mixers, compressors and process equipment. As it is in-house manufactured, you can ask about variants in diameter, number of grooves or finish according to your application.

This pulley has a 350 mm diameter, 5 grooves and section B. Section B corresponds to classic profile V-belts, and the five 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 transmission ratio when combined with the motor or driven equipment pulley. It is a cast iron or machined steel part, depending on the use, and is balanced to work at the usual speeds in the industry.

Typical applications include mills, mixers, screw compressors, industrial fans, centrifugal pumps and conveyors. In all these cases the goal is to transmit power from an electric motor or a gear reducer to the equipment, with the possibility of adjusting speed by changing the diameter. The 5-groove pulley is chosen when the torque to be transmitted is high or when you want to have margin in case a belt breaks, since the system can keep running with the remaining ones until the scheduled stop.

To correctly select this pulley, take into account the pitch diameter, the number of grooves, the belt section and the type of bushing or center bore. Check that the diameter of the driving and driven pulleys gives the desired transmission ratio and that the peripheral speed does not exceed the belt limits. During mounting, align the pulleys precisely, tension the belts according to the manufacturer's recommendation and check the parallelism of the shafts to avoid premature wear.

If you need a pulley with another size, another number of grooves or a different section, we can manufacture it. We can also analyze the replacement of an existing pulley from the sample or from the measurements taken. To do so, send us the outside diameter, the bore diameter, the number of grooves and the belt section you use. With that data we will quote you the equivalent pulley or the nearby size that best fits your machine.
