The 310 5B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 310 mm diameter and 5 grooves for section B belts. It is used to transmit power from a motor to a machine, maintaining the drive ratio and parallelism between shafts. It is a key part in power transmission systems that require several belts to distribute the load.

This pulley has a 310 mm outside diameter and 5 grooves for section B belts. Section B is one of the most widely used in industrial drives: it accepts classic V-profile belts. The 5 grooves allow several belts to be mounted in parallel, which spreads the load and improves drive reliability. The grooves are machined so that the belts seat correctly and do not slip.

It is used in compressors, fans, pumps, mills, conveyor belts and machine tools. Also in process equipment where the motor speed needs to be reduced or increased. It is common in installations that already have a section B pulley and belt system and need to replace a damaged pulley or change the drive ratio. Because it is in-house manufactured, MR can machine the bore and keyway to match the equipment shaft.

To select the pulley, take into account the pitch diameter, the number of grooves and the belt section. Check that the motor or machine shaft has a compatible diameter and keyway. The assembly must be aligned with the driving pulley to avoid irregular belt wear. If the pulley runs at high speeds, it is advisable to check the balancing. It is fixed to the shaft with a key and set screw or with a taper bushing, depending on the design.

If you need a pulley with a different size, a different number of grooves or for section A, C or 5V belts, we can manufacture it. To request an equivalent, send us the original pulley part number, the outside diameter, the number of grooves and the belt section. Also the shaft diameter and the type of fixing. With that data we will quote the pulley that best suits your equipment.
