The 480 4B pulley is a V-belt drive component manufactured by EMMAR. It features a 480 mm diameter and four grooves for section B belts, making it suitable for power transmission where multiple belts run in parallel. Typical applications include fans, compressors, pumps, and process machinery that take motion from a motor and transfer it to a driven shaft. Because it is produced in-house, the bore and keyway can be machined to match your specific requirements.

With a 480 mm diameter, four grooves, and section B profile, this pulley works with classic V-belts. The four grooves let you mount up to four belts side by side on the same sheave. The diameter, together with the driving pulley, sets the transmission ratio: a larger driven diameter reduces the speed at the driven shaft. Using more belts spreads the load across them, which helps maintain drive continuity.

This pulley suits power transmission setups that need to reduce speed and keep a steady operating regime. It is common in industrial fans, screw compressors, centrifugal pumps, mixers, and conveyors. It also fits process equipment that already has a smaller driving pulley and requires a 480 mm driven pulley with four belts to handle the necessary power. Always confirm that the shaft and pulley bore are compatible.

When selecting and mounting the pulley, consider shaft diameter, bore type (cylindrical or tapered), keyway, and fastening method. Verify that the belt section is B and that the number of grooves matches the number of belts you plan to use. Check alignment between pulleys; misalignment speeds up wear on belts and grooves. Tension should follow the recommendation for section B—neither too loose nor too tight—and it is wise to recheck after the first hours of operation.

For an equivalent pulley, send the part number 480 4B or specify the diameter and number of grooves you need. We can also review variants in groove count or diameter to adjust the transmission ratio. Provide equipment details: power, motor speed, driving pulley diameter, and shaft diameter. With that information, we will guide you to the most suitable option from our in-house manufacturing line.
