The EMMAR 170 3C is a 170 mm diameter, 3-groove, C-section V-belt pulley. It mounts on a shaft and transmits motion through multiple C-section belts, which allows the load to be shared across grooves. Because MR manufactures this pulley in-house, dimensions and groove geometry stay consistent from part to part.
The designation POLEA 170 3C tells you the key selection data: 170 mm diameter, three grooves, C section. C section is a wide V-belt profile, so this pulley is intended for drives that use C-section belts. Running three belts in parallel raises the torque the drive can carry and gives you a degree of redundancy—if one belt fails, the remaining belts can keep the equipment running until the next planned stop.
You will find this size on compressors, centrifugal pumps, high-flow fans, mills, mixers and other process plant transmission equipment. It also suits systems where several shafts must stay synchronized or where reliability matters more than saving space. With its diameter and groove count, it fits fixed medium- and high-power installations.
Before mounting, check that the shaft diameter matches the pulley bore and that the key is in good condition. Align the drive and driven pulleys so the belts run true; misalignment shortens belt and bearing life. Set tension according to the belt manufacturer's recommendation. When selecting a replacement, work from the transmitted power, shaft RPM and the service factor of the application.
If your drive calls for a different diameter, groove count or section, MR can manufacture that pulley. To request an equivalent or a custom piece, send the part number POLEA 170 3C, a drawing or a sample through WhatsApp or email. The team replies promptly and can help you confirm the right fit for your equipment.

Frequently asked questions
- What does C section mean on this pulley?
- C section is the V-belt profile the grooves accept. C-section belts have a defined width and height that seat in the groove. Using the correct section keeps the belt from sitting too deep or too shallow, which affects grip and wear.
- Can I run this pulley with only one or two belts instead of three?
- Yes, you can mount fewer belts, but the power the drive can transmit drops in proportion. If the application needs full capacity, use all three grooves. Share your operating conditions and we can help you judge whether fewer belts are acceptable.
- Does MR make pulleys to order?
- Yes. MR manufactures pulleys in-house, so we can produce sizes with different diameters, groove counts and sections. Send your specifications, drawing or sample by WhatsApp or email and we will follow up with a quote.
