The EMMAR 100 5B is a V-belt pulley with a 100 mm diameter, 5 grooves and section B. It is designed for drives that use multiple belts in parallel, such as industrial machines, fans and compressors. Because MR manufactures this pulley in-house, the machining and quality are controlled at every step.

The designation 100 5B tells you the key dimensions: a 100 mm diameter, 5 grooves and a section B profile. Section B matches classical V-belts, and the five grooves let you run up to five belts side by side to share the load. The diameter sets the drive ratio when paired with another pulley. The pulley is made from cast iron or machined steel, depending on the manufacturing process, and is supplied with the bore and keyway to your specification.

You will find this pulley in drives for industrial fans, screw compressors, centrifugal pumps, conveyor belts and machine tools. In these setups, multiple belts distribute the effort and reduce vibration. It also appears in refrigeration equipment and in tight spaces where a small-diameter, multi-groove pulley is needed. Plants that keep spare parts compatible with existing equipment often stock this size.

When selecting the 100 5B, check the pitch diameter, the number of grooves and the belt section. Confirm that the shaft bore matches your shaft diameter and that the keyway is correct. Balancing matters if the pulley runs at high speed. During assembly, align the pulleys to prevent premature belt wear. If you need a different size or groove count, ask us about alternatives in the series.

To find an equivalent, send the part number 100 5B by WhatsApp along with your drive data: shaft diameter, belt section and number of grooves. We can also manufacture a custom pulley if the standard line does not fit your equipment. MR makes pulleys and other drive components and can help you choose the right part for your machine.
