The EMMAR 420 5B is a V-belt drive pulley with a 420 mm diameter, five grooves, and a section B profile. It is designed for parallel-shaft drives that use multiple belts, such as fans, compressors, pumps, and conveyors. Since EMMAR produces this pulley in-house, you can request machining and balancing options tailored to your application.
This pulley has a 420 mm diameter, five grooves, and a section B profile. Section B refers to classic V-belts with a B cross-section, and the five grooves allow up to five belts to run side by side on the same pulley. The diameter determines the transmission ratio when paired with another pulley in the drive. The code 420 5B captures these three key details: diameter, groove count, and belt section.
Typical uses include drives that rely on multiple belts to share the load. You will find it on industrial fans, screw compressors, centrifugal pumps, screens, mixers, and conveyors, as well as on agricultural machinery and process equipment set up for section B belts. It serves as a general-purpose pulley for maintenance and replacement in existing transmission systems.
When selecting this pulley, confirm that your belts are section B and that the groove count matches the number of belts on your equipment. The 420 mm diameter must fit your desired transmission ratio and the available space. Before installation, inspect the keyway, the shaft fit, and the alignment between pulleys. A worn keyway or misalignment can reduce belt life.
If you need an equivalent pulley, provide the part number 420 5B or the complete equipment designation. We can review options for groove count, diameter, or bushing/bore type, provided the application permits. The more details you supply—shaft diameter, mounting style, belt type—the more accurate our proposal will be.
MR Industrial Accessories manufactures this pulley and offers it alongside belts, bushings, and supports for power transmission. To request a quote or ask about a different size, send the part number 420 5B via WhatsApp and we will respond with the best alternative for your machine.

Frequently asked questions
- What does the designation 420 5B indicate on a pulley?
- The 420 stands for the pulley diameter in millimeters, the 5 for the number of grooves, and the B for the V-belt section. It is a compact way to specify the three main variables of a pulley for section B belts.
- Can I run this pulley with belts of a different section?
- It is not advisable. The grooves are cut for the B profile. A belt of another section may not seat correctly, could slip, or wear out faster. If you need a different section, contact us about an equivalent pulley.
- How do I request a pulley with a different number of grooves or diameter?
- Send the part number 420 5B via WhatsApp and specify the diameter, groove count, or bore type you need. With that information, we will assess whether a variant can be manufactured or if a different pulley size is more suitable.
