Industrial pulley 550 mm, 3 grooves, section B

EMMAR POLEA 550 3B belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 550 3B and any equivalents.

The EMMAR 550 3B is a three-groove V-belt pulley in section B, built with a 550 mm diameter. It transfers power between parallel shafts on industrial drives such as fans, compressors, pumps, mills and conveyors. Because it is produced in-house, machining and balancing options can be adapted to the application. To replace an existing pulley or set up a new drive, share the part number and equipment details with our team to request a quote.

The 550 3B carries a 550 mm diameter, three grooves and a section B profile. Section B is among the most common V-belt sizes in plants, and three grooves allow more torque than a single-groove pulley of the same diameter. The 550 mm diameter sets the transmission ratio when paired with the pulley on the opposite shaft. This is an EMMAR in-house manufactured part, intended for continuous duty in plant environments.

Use this pulley in belt drives where speed must be reduced or increased between a motor and a machine. Typical equipment includes centrifugal and axial fans, screw and piston compressors, centrifugal pumps, mills, mixers, screens and conveyors. It also appears in mining, cement, food processing and water treatment. In every case, confirm the power to be transmitted, shaft speed and load type before choosing the pulley.

When selecting and mounting a section B pulley with three grooves, review motor power, the rpm of both fast and slow shafts, and the center distance. Groove count and diameter determine how many belts are needed and the resulting speed. Check pulley alignment, belt tension and groove condition; a worn groove speeds up belt wear. If the pulley mounts on a keyed shaft, verify the bore diameter and fixing type.

For an equivalent pulley, send the part number POLEA 550 3B or the original pulley data: diameter, number of grooves, section, bore diameter and fixing type. With that information we can propose the in-house manufacturing variant that fits. We can also review special machining, balancing and treatments for your use. The more complete the equipment information, the faster the response.

To request a quote for this pulley or ask about another size, send the part number via WhatsApp to MR Industrial Accessories. If you are unsure about the section, groove count or bore diameter, write to us with a photo or sketch of the part and the equipment data. We work with transmission lines and in-house manufacturing to solve replacements and complete assemblies.
