Description
EMMAR POLEA 420 3C 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 3C and any equivalents.
The EMMAR 420 3C is a V-belt pulley with a 420 mm outside diameter and three grooves for section C belts. It is used to transmit torque from a motor to a driven shaft in machines that run one or several C-section belts in parallel. Because it is manufactured in-house, the machining can be matched to your shaft and keyway requirements.
The part number POLEA 420 3C tells you the main specifications: 420 mm diameter, three grooves, and section C. The diameter is measured on the outside of the pulley. Section C is a classic V-belt size used in higher-power drives, and the three grooves let you run three C belts side by side on the same pulley.
Typical equipment includes milling machines, mixers, compressors, high-flow pumps, industrial fans, and continuous process lines. In these drives, the pulley transfers motion from the motor to the driven shaft. With three belts, the load is shared across the grooves, which helps handle the torque demand without overloading a single belt.
When selecting or replacing this pulley, check the shaft diameter, the keyway type and size, and the center distance of the drive. Confirm that the mating pulley also uses section C grooves and that the drive ratio is what you need. Alignment matters: angular or parallel misalignment will speed up wear on both belts and grooves. Also verify belt tension according to the belt type and load.
If your application calls for a different number of grooves, another diameter, or a different section, that can be reviewed within the same manufacturing line. Send the current part number, the shaft size, and the belt section you are using. With that information, we can determine whether another pulley from the same series fits or if a custom-machined part is required. MR produces its own pulleys, so adjustment is part of the process.
To request a quote for the POLEA 420 3C or to ask about an equivalent, send the part number by WhatsApp or email. If you are unsure about the section, number of grooves, or diameter, share the equipment details and we will help you choose. Keyway machining to match your shaft size can also be requested.

Frequently asked questions
- What does section C mean for this pulley?
- Section C is a standardized V-belt size that defines the width and height of the groove where the belt sits. This pulley has three grooves for section C, so three C belts can be used in parallel.
- Can I get a pulley with a different number of grooves?
- Yes. Since MR manufactures pulleys, a variant with more or fewer grooves in the same section can be evaluated. Send the current part number and the number of grooves you need so we can suggest an alternative.
- How do I check if this pulley fits my equipment?
- Check the shaft diameter, the keyway, and the belt section your equipment uses. With that data, compatibility can be confirmed. If you do not have them, send a photo of the old pulley and the shaft size.
