The POLEA 500 1B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 500 mm diameter, a single groove and section B, making it suitable for driving shafts with a B-profile belt. It is used in equipment where speed needs to be reduced or transmitted with a simple and reliable ratio, such as fans, pumps, compressors and conveyors. Because it is in-house manufactured, you can inquire about variations in diameter, number of grooves and finish.

This item is a pulley with a 500 mm diameter, 1 groove and section B. The designation POLEA 500 1B summarizes those three variables: the outside diameter, the number of grooves and the belt profile. Section B corresponds to type B V-belts, widely used in medium-power industrial drives. The groove is machined so that the belt seats correctly and contact is even across the entire arc. The pulley is supplied without belt or bushing, unless ordered as a set.

Typical applications for a 500 mm pulley with one section B groove are moderate-speed equipment: centrifugal fans, water pumps, screw compressors, conveyor belts and factory machinery. It is also used as a driven pulley in single-ratio reducers, where the goal is to lower motor RPM without resorting to a gear reducer. In all cases, it is advisable to verify that the power to be transmitted and the working RPM are within the allowable range for a section B belt.

To mount this pulley, first check the shaft diameter and the type of fastening: it can be keyed, taper bushed or set screw mounted, depending on how the equipment is set up. Then check the alignment between the drive and driven pulleys, because misalignment accelerates wear on the belt and the groove. Belt tension is adjusted according to the equipment manual or standard practice for section B. If you are replacing an existing pulley, take the diameter, number of grooves and section as minimum data.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 500 1B or the data of the original pulley: diameter, grooves, section and shaft diameter. With that we can verify if there is an in-house manufactured variant that fits. We can also evaluate whether it is advisable to move to two or more grooves for the same power.
