Description
EMMAR POLEA 330 4C 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 330 4C and any equivalents.
The 330 4C pulley is a V-belt drive component with a 330 mm diameter and 4 grooves, designed for section C belts. Manufactured in-house under the EMMAR brand, it transmits torque from a motor to machine shafts, making it suitable for drives that need a large-diameter, multi-groove pulley to share the load across several belts.
With a 330 mm diameter, 4 grooves, and section C profile, this pulley accommodates wide-profile V-belts. The four grooves allow up to four belts to run in parallel, distributing the load. The diameter sets the transmission ratio when paired with another pulley in the same drive. As an in-house manufactured EMMAR product, it is not a third-party item.
Typical applications include compressors, mills, mixers, high-flow pumps, industrial fans, and continuous process machines that rely on section C belts. It is also used in drives where motor speed is reduced and torque on the driven shaft is increased. The multiple grooves enable load sharing and continued operation if one belt fails.
During installation, verify that the shaft and keyway match the pulley bore and that the driving and driven pulleys are properly aligned. Both pulleys must have the same number of grooves so all belts work together. Adjust tension according to the belt type and center distance. When replacing a pulley, confirm the diameter, section, and number of grooves before ordering.
To request a quote, send the part number, diameter, section, and number of grooves. A photo of the old pulley or the belt data also helps. With that information, we can check if an equivalent pulley exists in the in-house manufacturing line or if a custom-made solution is more suitable.

Frequently asked questions
- What does section C mean on a pulley?
- Section C refers to the V-belt profile that fits into the pulley groove. It determines the groove width and depth. A section C pulley is designed to work only with section C belts and is not compatible with other belt sections.
- Can I use fewer belts than grooves?
- Yes, but the transmission capacity decreases. Each additional groove helps distribute the load. If you use fewer belts than the pulley allows, ensure the power to be transmitted does not exceed the capacity of the installed belts.
- How do I order a pulley in another size?
- Send the diameter, section, number of grooves, and the type of bore or keyway via WhatsApp. With that information, we can identify an equivalent pulley in the in-house manufacturing line, EMMAR brand, or arrange a custom-made unit.
