The EMMAR 340 5C is a section C V-belt pulley built for drives that link parallel shafts, with a 340 mm diameter and five grooves. Five belt paths let the drive carry more load than a single-belt sheave of the same diameter, which suits equipment where the ratio must stay steady under continuous duty. MR Industrial Accessories supplies this model from its own pulley manufacturing line, so groove geometry and balance are checked at the shop before the unit ships.
Read the code before you order: POLEA 340 5C gives the diameter first (340 mm), then the groove count (5), then the belt cross-section (C). Section C belts sit at the top of the classic V-belt range for power capacity, so a five-groove sheave in this section is normally chosen for heavier drives running at moderate speeds. The 340 mm diameter fixes the rim speed at a given shaft rpm, while the groove count sets how many belts share the load.
Typical installations include screw compressors, mills, mixers, high-flow centrifugal pumps, industrial fans, screens and belt conveyors, plus other continuous-process lines. In these drives the extra grooves are useful because output can be raised by adding belts rather than swapping the sheave for a larger one, which keeps the ratio and the rest of the drive layout unchanged.
Before mounting, confirm the shaft diameter and keyway match the bore, and line the sheave up with its counterpart on the driven side. Misalignment between grooves is a common cause of uneven belt wear and vibration. For selection, work from the power to be transmitted, the shaft speed and the target ratio; with a 340 mm pitch diameter and five section C grooves you can size the belt count and pick the matching sheave for the other shaft. Where the envelope is tight, check the outside diameter and the hub width as well.
Because the pulley comes from MR's own manufacturing, critical dimensions such as groove profile, pitch and concentricity are controlled during machining, which helps belts seat correctly and limits slip and early wear. If you are replacing a worn sheave or assembling a new drive, send the designation POLEA 340 5C through WhatsApp or email with the shaft details, and the team will quote it and suggest the complementary pulley for the drive.

Frequently asked questions
- What does the designation POLEA 340 5C tell me?
- It identifies the pulley by size and belt fit: 340 mm diameter, 5 grooves, section C. Those three values are what you need to compare it against the sheave currently on the drive.
- Can this pulley replace the one on my machine?
- It can if the diameter, groove count, belt section and shaft fit all match. Send the data from the original pulley and the team will confirm whether the 340 5C works or point you to a different size.
- How do I ask for a different diameter or groove count?
- Message the team with the diameter, number of grooves and belt section you need. Since MR manufactures its own pulleys, a custom piece in the section C line can be reviewed, and the more detail you provide, the quicker the answer.
