Description
EMMAR POLEA 650 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 650 4C and any equivalents.
The EMMAR POLEA 650 4C is a 650 mm diameter, four-groove pulley for section C V-belts. It mounts on a machine shaft to transmit or receive motion, and it is manufactured in-house by MR Industrial Accessories. Typical uses include industrial fans, compressors, pumps, conveyors and mixers that rely on multiple belts to share the load.
The part number POLEA 650 4C tells you the key selection data: 650 mm diameter, 4 grooves and section C. Section C is a medium V-belt profile that can handle moderate to high power depending on diameter and groove count. Four grooves let the drive spread the load across four belts, which lowers the tension on each belt and helps keep the drive running smoothly.
This pulley suits continuous-process equipment such as high-flow fans, screw compressors, large centrifugal pumps, belt conveyors and mixers. It also appears in machine tools and in drives that need a stable speed ratio and low maintenance. Because MR manufactures the pulley, the bore and keyway can be machined to match the shaft of the equipment it will serve.
When selecting a 650 mm, 4-groove, section C pulley, confirm the shaft diameter, the fixing method (keyway, taper bushing or set screw), the center distance and the target transmission ratio. Check alignment between pulleys and belt tension as well, since misalignment speeds up wear on the grooves and belts. Choose the number of grooves from the power to be transmitted and the diameter of the driving pulley.
If you need a different groove count or a pulley for another shaft, send the part number POLEA 650 4C by WhatsApp along with the equipment details: shaft diameter, belt section, number of grooves and center distance. With that information, MR Industrial Accessories can offer an alternative from its in-house manufacturing line or advise whether a custom pulley makes sense. You can also ask about machining the bore and keyway.
MR Industrial Accessories manufactures this pulley and sells it directly. If your equipment runs a section C belt drive and you need to replace a 650 mm four-groove pulley, message us on WhatsApp with POLEA 650 4C and we will prepare your quote. We can also help with mounting and alignment so the drive runs evenly over time.

Frequently asked questions
- What does POLEA 650 4C mean?
- It identifies a 650 mm diameter pulley with 4 grooves for section C V-belts. The four grooves let the drive distribute power across four belts, which suits medium to high power industrial transmissions.
- Can I request a different number of grooves or a different diameter?
- Yes. Since the pulley is manufactured in-house, MR can machine other sizes, groove counts or sections. Send the shaft diameter, belt section and number of grooves you need by WhatsApp, and we will quote the alternative.
- How is a 650 mm pulley with 4 grooves mounted?
- It mounts on the shaft using the applicable fixing method (keyway, taper bushing or set screw) and must be aligned with the driving pulley. Check belt tension and alignment to avoid premature wear on grooves and belts.
