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, which makes it suitable for driving shafts with a profile B 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. As it is in-house manufactured, you can ask about variants of 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 the contact is even along the entire arc. The pulley is supplied without belt or bushing, unless requested as an assembly.

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 machines. It is also used as a driven pulley in single-ratio reducers, where the goal is to lower the 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 admissible range for a section B belt.

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

If you need an equivalent pulley, send us the part number POLEA 500 1B or the data of the original pulley: diameter, grooves, section and shaft diameter. With that we propose the 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.
