The 550 6B pulley is a V-belt drive pulley, section B, with a 550 mm diameter and 6 grooves. It is used to drive shafts in industrial equipment where torque must be transmitted with several belts in parallel, for example in fans, compressors, pumps and process machines. It is in-house manufacturing, EMMAR Accesorios Industriales brand, so the bore and keyway machining can be adjusted to the shaft it is mounted on.

This item is a pulley with a 550 mm diameter, 6 grooves and section B. The designation POLEA 550 6B summarizes those three data points: the outside diameter, the number of grooves and the belt profile it accepts. The grooves are machined for section B V-belts, so that the six belts work in parallel on the same diameter. It is a cast iron or machined steel part, depending on the use, and is supplied with the bore and keyway according to the destination shaft.

Typical applications are equipment that needs to transmit power from an electric motor or a gearbox to a working shaft: centrifugal and axial fans, screw compressors, centrifugal pumps, screens, mixers and conveyors. It is also used in process machines where the drive ratio is defined by the diameter of the driving and driven pulleys. With six grooves the load is distributed among several belts, which allows handling higher power than with a pulley with few grooves.

To select the pulley, it is advisable to start from the power to be transmitted, the RPM of the driving and driven shafts, and the section B belt type already defined for the equipment. Then the pitch diameter, the number of grooves and the bore diameter with its keyway are verified. During assembly, check the alignment between pulleys with a straightedge or laser, the belt tension according to the belt manufacturer's manual, and the tightening of the set screws or the taper bushing, if fitted.

If you need a nearby size, another diameter or a different number of grooves, it can be manufactured to order within the section B pulley line. To request an equivalent, provide the full part number of the original pulley, the diameter, the number of grooves, the belt section and the bore diameter with keyway. With that data it is compared against the drawing and it is determined whether a standard pulley or special machining is best.

MR Accesorios Industriales manufactures this pulley and also split plummer block housings, ANSI chains and other pulleys.
