The 250 2A pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 250 mm diameter and two grooves for section A belts. It is used to transmit motion between parallel shafts in industrial equipment, where a defined transmission ratio and stable running are required. As part of the in-house manufacturing line, EMMAR Accesorios Industriales brand, it is produced under our own control and you can inquire about alternative dimensions and configurations.

This item is a pulley with a 250 mm diameter, with 2 grooves and section A. The designation POLEA 250 2A summarizes those three variables: the 250 mm outer diameter, the number of grooves (2) and the belt profile it accepts, section A. It is a single-body pulley, designed to be mounted on a shaft and to receive two V-belts of the same profile. Section A defines the width and depth of each groove, so that the belt seats with the correct contact on the flanks.

Typical applications appear in transmission lines where speed needs to be reduced or increased between a motor and a machine: fans, compressors, centrifugal pumps, conveyor belts and process equipment. It is also used in machine tools and in drive systems where mounting space is limited and it is preferable to solve the transmission with belts instead of rigid couplings. Having two grooves makes it possible to double the transmission capacity or to keep running with a single belt if the other is removed for maintenance.

To select and mount this pulley, first verify the shaft diameter and the type of keyway or fastening system your machine needs, because those data are not included in the designation and are confirmed against a drawing or sample. Then check the center distance and the available belt length so that the tensioner has enough travel. The alignment between driving and driven pulleys must remain within tight tolerances: angular or parallel misalignment accelerates wear on the belt and the grooves. Finally, check that section A is the one that corresponds to your belts; if in doubt, send us the belt code and we will cross-reference it.

If you need a nearby size or an equivalent, the most practical approach is to send us the full code of the pulley you are replacing, the number of grooves, the belt section and the shaft diameter. With that data we can verify whether the 250 2A pulley fits directly or whether a variant with another diameter, another number of grooves or a different fastening system is preferable. We can also evaluate machining a keyway or a bushing according to your application, as long as you provide the drawing or the sample.

To request a quote for the 250 2A pulley or ask about an alternative, send the code POLEA 250 2A via WhatsApp to MR Accesorios Industriales. If you have doubts about the section, the number of grooves or the mounting, attach a photo of the current pulley and the shaft dimensions. That way we will reply with the option that best fits your transmission, without hassle.
