Description
EMMAR POLEA 420 6C 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 420 6C and any equivalents.
The EMMAR 420 6C is a V-belt pulley with a 420 mm diameter, six grooves and section C profile. It is manufactured in-house, which allows control over machining and balancing so that belts seat properly and wear evenly. This pulley is used to transmit power from a motor to a driven shaft at a different speed in industrial equipment.
Section C designates a wide V-belt profile suited to medium and high power transmission. Because the 420 6C has six grooves, several section C belts can run side by side on the same pulley, sharing the load. The 420 mm diameter is a key factor in setting the speed ratio when this pulley is paired with another in the drive system.
Typical applications include drives for mills, mixers, compressors, centrifugal pumps, fans and conveyors. It is also found in wood, plastic and food processing machinery where the motor is located at a distance from the working shaft. In these setups, the six-groove section C pulley helps carry motion with few losses and absorbs the vibrations that occur during startup.
During installation, make sure the shaft and keyway are clean and free of burrs, and that the pulley fits correctly. Align the pulleys with a straightedge or laser before tensioning the belts; misalignment speeds up wear on both grooves and belts. Adjust tension according to the equipment manual: too loose and the belts slip, too tight and the shaft bearings suffer.
If you need a different diameter, number of grooves or section, send us the equipment data or the original pulley designation. With diameter, grooves and section we can locate an equivalent within the same line. We can also verify the keyway and bushing type if the mounting requires it.
MR Industrial Accessories LLC manufactures this pulley as part of its power transmission line. If you have the part number POLEA 420 6C, send it via WhatsApp or email and we will quote you. If the number does not match, send a photo of the pulley and the shaft dimensions so we can help you identify the right part.

Frequently asked questions
- What does section C mean?
- Section C is a V-belt profile wider than sections A or B. It transmits more power per belt. The 420 6C pulley has six grooves of that profile, so up to six section C belts can be mounted in parallel.
- How do I request a pulley equivalent to the 420 6C?
- Send the diameter, number of grooves and section of the original pulley by WhatsApp. If you have the equipment part number or a photo, even better. With that data we look for the equivalent within the same manufacturing line.
- What should I check before mounting it?
- Check that the shaft and keyway are clean and free of burrs, and that the pulley fits correctly. Then align the pulleys and tension the belts according to the equipment manual. Poor alignment or incorrect tension shortens the life of belts and bearings.
