The 250 2A pulley is a power transmission pulley of in-house manufacturing, 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 operation are needed. Being part of the in-house manufacturing line, EMMAR Accesorios Industriales, it is produced under own control and can be consulted for alternative sizes and configurations.

This item is a pulley with a 250 mm diameter, 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 receive two V-belts of the same profile. Section A defines the width and depth of each groove, so that the belt seats with 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 drive systems where mounting space is limited and it is convenient to solve the transmission with belts instead of rigid couplings. Having two grooves allows doubling the transmission capacity or maintaining operation 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 fixing 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 the tensioner has sufficient travel. The alignment between driving and driven pulleys must be within tight tolerances: angular or parallel misalignment accelerates belt and groove wear. Finally, check that section A is the one corresponding to your belts; if in doubt, send us the belt part number and we'll cross-reference it.

To quote the pulley you are replacing, the most practical is to send us the complete part number, the number of grooves, the belt section and the shaft diameter. With that data we propose the corresponding 250 2A pulley or a variant with another diameter, another number of grooves or a different fixing system. We can also evaluate machining a keyway or a bushing according to your application, as long as you provide the drawing or sample.

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