It is in-house manufactured, EMMAR brand, which allows controlling the machining of the groove and the balancing. If you need a pulley for your equipment, send us the part number by WhatsApp and we'll quote you.

This pulley has a 250 mm diameter, 1 groove and section C. Section C corresponds to wide-profile V-belts, suitable for transmitting medium and high power in industrial applications. The groove is machined so that the belt seats correctly and the outer diameter allows calculating the tangential speed according to the shaft rpm. It is an in-house manufactured part, EMMAR brand, designed to replace worn pulleys or to build a new drive.

It is used in fans, compressors, pumps, mills, conveyor belts and machine tools. Also in industrial laundry equipment, mixers and extraction systems. Because it is single-groove, it is common in simple drives where redundancy or high power is not required. If the original equipment comes with a 250 mm section C pulley, this can be the replacement, as long as the shaft diameter and the keyway are verified.

To mount it, check that the shaft diameter matches the pulley bore and that the keyway is the right one. The pulley is fixed with a key and set screw or with a tapered fixing system, depending on the case. It is important to align the pulleys to avoid irregular belt wear and vibrations. The belt tension must be correct: too loose it slips, too tight it overloads the bearings. If you do not know the shaft size, measure it with a caliper.

If you need a pulley with another diameter, another number of grooves or a different section, we can manufacture it. We can also quote an equivalent pulley if you send us the shaft dimensions, the keyway and the belt section. For that, send us the part number MR-POLEA-C1-250 or a photo of the old pulley with the measurements by WhatsApp. At MR Accesorios Industriales we have more than 80 years of experience in power transmission and we can advise you.
