The EMMAR 360 4B is a V-belt drive pulley built in-house by MR Industrial Accessories LLC. Its 360 mm diameter, four grooves and section B profile suit drives where several belts run side by side to share the load. You will find this size on industrial machines, pumps, fans and conveyors, and because it is manufactured in-house, machining and balancing options can be discussed for your specific application.

Reading the designation is straightforward: 360 mm is the diameter, 4 is the number of grooves and B is the belt section. Four grooves mean four B-section V-belts can run in parallel, spreading the load across the drive. Combined with a second pulley, the 360 mm diameter sets the drive ratio of the system. Depending on the application, the pulley is produced in cast iron or machined steel, and it is balanced to keep vibration low at normal operating speeds.

Typical installations include centrifugal pumps, fans, compressors, conveyors, mixers and process equipment, as well as agro-industrial operations and water treatment plants. When a machine is originally fitted with a four-groove section B pulley, this diameter often shows up on medium-flow pumps and induced draft fans. It is also a part that maintenance teams replace regularly, so matching the original dimensions matters.

Selection comes down to a few checks: the outside or pitch diameter the machine calls for, the number of grooves and the belt section. A section B pulley will not accept A, C or 5V belts, so a section change means changing the belts as well. Confirm the shaft diameter and keyway type too, since the bore is machined to order. On high-speed drives, it is worth reviewing the balancing. At installation, align the pulleys and set belt tension as the equipment manual specifies.

If the exact size is not listed, a custom pulley can be made to your diameter, groove count and section. Swapping to a different section is also possible when the belt set is changed at the same time. To move forward, send the drive details: driving and driven pulley diameters, belt section, number of grooves and shaft diameter. With those data points, the right part can be quoted.
