This industrial pulley of 550 mm diameter and one groove for section B belt is a power transmission part manufactured by EMMAR Accesorios Industriales. It is used to transmit movement between shafts by means of V-belts, in installations where a defined drive ratio and good grip are needed. Its in-house construction allows adjusting the machining to the needs of the equipment, and it is an alternative to replace worn pulleys or to build a new drive.

The 550 1B pulley has a 550 mm diameter, a single groove and houses section B belts. The designation indicates exactly that: 550 outside diameter and 1B for one groove for profile B. It is a large-diameter pulley, designed to be mounted on machine and motor shafts, and it is manufactured at MR with the machining and balancing corresponding to this type of part. Because it is in-house manufactured, you can inquire about variants of diameter, number of grooves or type of hub.

It is used in belt drives of industrial machines: compressors, fans, pumps, mills, mixers, conveyor belts and process equipment. It also appears in the drive of tools and in production lines where the speed needs to be reduced or increased between the motor and the driven shaft. Due to its diameter, it is common in low-speed and high-torque applications, where the section B belt offers adequate load capacity for the transmitted power.

To select a pulley of this type you must take into account the pitch diameter, the number of grooves, the belt section and the diameter of the shaft where it is mounted. The fastening system also matters: keyway, hub with screws or taper bushing, depending on the case. During mounting, check the alignment between pulleys, the belt tension and that the keyway fits without play. An off-center or misaligned pulley shortens the life of the belt and of the equipment bearings.

If you need a different size, an equivalent or a pulley with more grooves, send us the equipment data: diameter, section, number of grooves and shaft diameter. With that we can see if there is an in-house manufactured pulley that fits or if it is better to machine a custom one. We can also help you define the drive ratio if you send us the motor revolutions and those of the driven shaft, and the data of the belt you are using.

To request a quote for this pulley or to inquire about a variant, write to us by WhatsApp and send us the part number POLEA 550 1B. If you have an old pulley to replace, send a photo or the measurements taken with a caliper and we will tell you with which MR option we can replace it. We handle technical inquiries Monday to Friday and ship throughout the country.
