The 310 4B pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a 310 mm diameter and 4 grooves for section B belts. It is used to transmit power between parallel shafts in industrial machines and equipment, where a defined transmission ratio and capacity for several belts are needed. As it is from in-house manufacturing, variants of machining and balancing can be requested according to the application.

This pulley has a 310 mm outer diameter, 4 grooves and section B. Section B corresponds to classic V-belts with a B profile, and the 4 grooves allow up to four belts to be mounted in parallel on the same pulley. The 310 mm diameter defines the transmission ratio when combined with another pulley of the same type. It is a cast iron or machined steel part, with ground grooves so that the belt seats evenly and does not wear prematurely.

It is used in power transmissions of machine tools, compressors, fans, pumps, conveyor belts and process equipment. It also appears in agro-industrial applications and in maintenance workshops that replace worn pulleys or change the transmission ratio. Having 4 grooves, it is suitable for transmitting relatively high torques with section B belts, as long as the drive calculation confirms it.

To select a pulley like this one, the pitch diameter, the number of grooves, the belt section and the type of bushing or bore must be verified. The rotation speed, the power to be transmitted and the alignment between pulleys also matter. During mounting, it is advisable to check concentricity, belt tension and the condition of the grooves. If the pulley is mounted on a shaft with a keyway, the fit tolerances must be respected.

If you need an equivalent pulley or a nearby size, send us the part number, the number of grooves and the belt section. It also helps if you send us the current diameter, the type of bore and a photo of the part. With that data we can verify whether we have a pulley with similar characteristics or whether it is better to manufacture it. We work with standard sizes and with custom developments within our power transmission line.
